Release notes

View the history of B2CONNECT releases with key points and major updates highlighted

Systematic Hedging, introduced in the previous release, has been hardened to stay reliable under high-frequency, high-volume flow such as copy-trading and HFT bursts. B2CONNECT shapes the incoming client flow so that only the residual net position is routed to each liquidity provider (LP), keeping order placement comfortably within venue API rate limits even during tick storms. In the B2CONNECT Web UI, the real-time Risk Status view and its cumulative order-accumulation status bar now update accurately at very high request rates, so risk teams keep a precise, live picture of how exposure is building and when it will hedge.

More flexible symbol and instrument naming

The liquidity aggregator integration now supports independent taker-side and maker-side symbols. Previously both legs shared a single venue name, causing a platform to distribute the LP’s symbols to the FIX clients. B2CONNECT now resolves the incoming FIX symbol against a dedicated taker symbol and maps it to the liquidity aggregator catalog name separately — so brokers can keep their own client-facing symbology regardless of an LP’s naming.

Asset and trading instrument names can now also include the ampersand (&) character. Such symbol names are accepted directly, removing the previous need to substitute AND.

Reduced noise from stale-liquidity alerts

Stale-liquidity alerts triggered by delisted symbols now fire once instead of repeating, cutting alert noise for monitoring teams when a venue delists an instrument.

Resolved issues

Resolved an issue where a market-data subscription on WebSocket liquidity venues (such as Kraken, Huobi, and Binance) could remain silent after a connector reconnect, leaving the affected symbols without fresh quotes — and FIX clients receiving only invalidations — until the connector was restarted. Such subscriptions now recover automatically.
Resolved an issue in the liquidity aggregator integration where a transient quote-cancel message was treated as a permanent subscription rejection, silently stopping quote publishing for the symbol until a restart. Transient cancels no longer drop the subscription, so streaming resumes as soon as the venue sends the next quote.

New features

Systematic Hedging

B2CONNECT introduces Systematic Hedging, a new execution option that complements — and does not replace — standard straight-through processing (STP). When enabled for a symbol, B2CONNECT aggregates incoming client flow into a managed risk position, nets opposing buy and sell volume, and hedges only the net residual to the liquidity provider (LP).

This gives risk teams tighter control over exposure and lower execution costs. And because only net positions are hedged, platforms send far fewer orders to their LPs — staying comfortably within API rate limits and easing the load on each provider, so every LP connection goes further.

Hedging stays fully under the risk team's control and is set per symbol: trigger by accumulated volume, a timer, a schedule, or manually; tune the hedge ratio and lock-routing behavior; or keep routing large orders straight through. The B2CONNECT Web UI adds a Symbol Hedging Configuration page, a real-time Risk Status page, and a master toggle, and risk-position state is restored automatically after any restart — so exposure is never lost or double-counted.

B2CORE integration

B2CONNECT now integrates with B2CORE, the B2BROKER ecosystem's CRM — the centralized control center for a brokerage's front-end client experience and back-end administrative operations. By connecting margin accounts on the B2CONNECT hub directly to B2CORE, the integration gives B2B clients who power their trading platforms with B2CONNECT seamless account onboarding and a streamlined day-to-day experience, with account creation, funding, and balance management all handled from one control center. It also puts the wider advantages of the B2BROKER ecosystem within reach on a single, connected stack.

Administrators set up and manage the connection from a new B2CORE Integration page in the B2CONNECT Web UI.

Tiered commission profiles

B2CONNECT now supports tiered commission profiles, which automatically lower the commission rate as an account's traded volume grows. Administrators define volume thresholds and the rate that applies beyond each one; B2CONNECT tracks cumulative volume over the chosen period — for example, a calendar month — and steps the rate down as each threshold is reached, including on liquidation orders.

For brokers, this turns growing volume into lower costs: the more flow through the hub, the lower their own per-trade commission — rewarding scale and protecting margins as the business grows.

Resolved issues

There have been no customer-facing issues reported in this release.

April 30, 2026

New features

Tiered margin profiles

B2CONNECT now supports tiered margin profiles, allowing Administrators to apply different margin rates to different slices of an account's notional exposure. Each profile can define up to five threshold–rate pairs per symbol, so brokers can mirror the bracketed margin schedules used by major liquidity providers — without falling back on inflated blanket rates that deter retail traders or on manual, position-by-position adjustments.

This delivers predictable, schedule-aligned leverage on every tranche of a client's position and removes a recurring source of operational overhead for risk and operations teams.

Hub Reports under TRAM

A new Hub Reports section is now available under TRAM (Tracking, Reporting, Alerting, and Monitoring) in the B2CONNECT Web UI, bringing reporting for margin accounts together in a single place. Back-office operators can request, track, and download reports directly from the platform — an important milestone in the rollout of TRAM, the unified reporting and observability layer for B2CONNECT.

The initial release of Hub Reports ships with three reports:

Consolidation Statement — a complete picture of an account's activity and exposure for any reporting period, including opening and closing balances, deposits, withdrawals, fees, opening and closing equity, unrealized PnL, used and free margin, margin utilization, and a dedicated Open Positions section listing each position's symbol, direction, average price, unrealized PnL, and margin. Account names are populated automatically, so each statement is clearly attributed.
Trading Report — per-trade execution details for one or more margin accounts over a chosen date range, delivered as a CSV. Each row includes the connection used, taker login and order identifiers, executed price and volume, and commission, giving back-office and reconciliation teams everything they need to audit individual fills.
Turnover (Traded Volume) Report — aggregated traded volume per account and per symbol for the selected period, supporting fee schedules, rebate calculations, and periodic client reviews.

Improvements

Binance Futures WebSocket endpoints

B2CONNECT has been migrated to Binance's new WebSocket URL architecture for perpetual futures, which separates traffic into dedicated public, market, and private channels. Brokers connecting to Binance Futures via B2CONNECT will continue to receive uninterrupted market data and order updates after Binance retires the legacy WebSocket URLs on 2026-04-23, with no action required on the broker's side.

Stream update reliability for Incoming Connectors

Subscription updates on Incoming Connectors are now more resilient under load. The platform allows more time for new streams to take effect and automatically retries on transient failures, preventing the rare cases where a slow update could leave a maker's symbols without fresh quotes until the next resubscription cycle.

Resolved issues

Resolved a consistency issue in the oneZero quoting integration where unsubscribing and immediately resubscribing to a symbol could occasionally fail with a duplicate-request error, leaving the symbol without market data until the next resubscription cycle. Resubscriptions are now handled atomically.

March 2, 2026

New features

Automatic account liquidation on stop-out

B2CONNECT now automatically liquidates open positions when an account's equity falls to the stop-out level, eliminating the need for manual intervention during margin events. The liquidation process executes iteratively — the system sends liquidation orders for all active positions, waits for each to reach a final state, and then evaluates whether the account has recovered before scheduling the next iteration. If the account's margin recovers above the stop-out threshold at any point, liquidation halts immediately.

The engine is designed for operational reliability: if a restart occurs mid-liquidation, the process resumes safely without duplicating or missing orders. Execution uses live market pricing to ensure liquidation orders reflect current conditions, preventing margin miscalculations during volatile periods. The waiting period before liquidation begins and the retry policy between iterations are configurable.

Improvements

Account cache reliability

The account management system now supports per-account cache reinitialization. When a cache error is detected, only the affected account's state is rebuilt rather than triggering a broader reset. This targeted recovery approach improves stability and reduces the potential for stale account data to affect margin calculations or order routing during error-recovery scenarios.

Resolved issues

There have been no customer-facing issues reported in this release.

February 27, 2026

New features

New B2CONNECT website and deep Insights

This February release is dedicated to documentation updates.

Improvements

Liquidity engine performance, stability, and security enhancements

We've delivered a set of improvements across the quoting and trading engine to increase overall performance and operational robustness. These updates include several security and stability hardening primarily related to the underlying technology stack and runtime components that support core execution workflows.

Resolved issues

There have been no customer-facing issues reported in this release.

January 30, 2026

New features

Incoming Connectors: Trading Settings tab

A new dedicated Trading Settings tab is now available for Incoming Connectors, allowing the Hub Administrators to configure symbols directly within the connector setup. This streamlines onboarding of new liquidity providers and simplifies ongoing symbol configuration and updates.

Improvements

Improved FIX credentials compatibility

FIX credential settings for supported liquidity aggregators are now more aligned with the standard FIX naming convention, ensuring more consistent configuration and reducing setup friction.

More descriptive error messages

Incoming Connector pages now display clearer, human-readable error messages in two common cases: when credential validation fails, and when the Administrator tries to enable trading for a symbol that’s disabled in Hub settings. These messages help identify the issues, so troubleshooting is more straightforward.

Resolved issues

Generated FIX credentials no longer start with an underscore in SenderID or TargetID, resolving compatibility issues with counterparties that reject such values.

December 22, 2025

New features

Perpetuals data over FIX: funding rate, mark price & funding interval

B2CONNECT now enriches FIX market‑data streams with FundingRate, MarkPrice, and FundingInterval fields, allowing any FIX‑compatible platform to price and offer perpetual futures out of the box. These parameters are delivered alongside standard quote updates in the FIX contract, eliminating the need for custom side channels or additional integrations to pass funding data.

Interest on idle cash and unused margin (AMS)

The AMS module now supports paying interest on idle cash and unused margin via dedicated Interest rate profiles in the Web UI. Administrators can configure per‑asset interest rates and a daily posting time in UTC; B2CONNECT then accrues interest automatically and posts it once per day as separate Interest transactions on client accounts. Brokers, exchanges, and other trading platforms are empowered to create a clear incentive for end-users (traders) to keep extra funds in their accounts, strengthening client retention and serving as a strong competitive differentiator.

Improvements

Maker credentials management inside Incoming Connectors

Trading and quoting Maker credentials are now configured directly within each Incoming Connector. Administrators can add, revoke, and review credentials in the same place where they manage the connection, reducing context switching and keeping connectivity and access control aligned per connector.

Target maker

A new Target maker control has been added to the Incoming Connectors page, making it straightforward to set or review which maker is currently used for routing. This improves transparency around active maker selection and simplifies switching and validating liquidity sources.

Resolved issues

There have been no customer-facing issues reported in this release.

October 30, 2025

New features

New docs section: Supported FIX platforms

With this release, we’ve added a new FIX platforms section to our documentation, showcasing trading platforms compatible with B2CONNECT via the FIX protocol. This new catalog includes baseline configuration guides and is linked to our FIX API reference. Integration teams can now quickly verify FIX compatibility and access the appropriate configuration templates from a single location, streamlining the setup process.

Improvements

Deep order recovery on LP disconnects

We’ve moved from a conservative recent‑orders snapshot to a controlled step‑by‑step rebuild that thoroughly recovers pending orders after a disconnect. As before, requests respect each Liquidity Provider’s API limits; the updated pacing keeps us right at the safe edge, delivering a far higher recovery count without triggering rate‑limit bans. Expect more complete catch‑ups on high count bursts and during volatile periods.

Resolved issues

There have been no customer-facing issues reported in this release.

September 30, 2025

New features

Internal risk warehousing (formerly B-Book)

B2CONNECT clients can now execute selected symbols internally within the crypto-native liquidity hub, retaining spread and reducing external fees. This new execution model provides per-symbol control to enable internal execution where it’s commercially advantageous, empowering clients to optimize their risk-return profiles with unprecedented precision. The configuration can be managed via CSV.

Partial risk internalization (formerly C-Book)

B2CONNECT clients can now optimize risk management with configurable order splitting between external hedging and internal execution. Set hedge ratios per symbol (0-100%) to determine the split, where the internal portion mirrors external fill pricing and proportions exactly. This approach reduces commission costs while maintaining risk control and supports both market and limit order flows.

Price invalidation for synthetic symbols

Synthetic markets now support invalidation signals the same way as organic symbols, providing consistent invalidation behavior across all symbol types. This development unlocks safe production deployment of the invalidation feature, providing traders with more reliable price feeds and reducing the risk of stale quotes across the entire trading ecosystem.

Liquidity acquisition configuration via incoming connectors

The configuration of liquidity acquisition service has been migrated from a global CSV to a structured, connector‑based flow. The new approach includes bulk asset upload capabilities, automated symbol-to-maker listing matching, and quoting CSV configuring, reducing setup time and potential errors while enabling more granular control over individual service instances.

Improvements

WebUI modernization

The Admin panel interface has been enhanced delivering improved usability.

The following upgrades land across the AMS accounts, AMS profiles, Notifications, Incoming Connectors and Symbols sections:

Navigation enhancements:
- Streamlined menu structure with fewer clicks to access key data.
- Relocated Notifications to Hub settings for better organization.
- Expanded table layouts for improved data visibility.
Single Sign-On:
- Centralized identity provider with standards-based SSO.
- Unchanged sign-in experience for end users.
- Continued user management capabilities for B2CONNECT administrators.

Additionally, the sidebar has been redesigned, with rebuilt left navigation reflecting the new information architecture, making the Liquidity, Symbols, Accounts, and Settings sections easier to access.

AMS profiles: CSV import/export

The Commission and Margin Requirements profiles setup has been accelerated through an import wizard and one‑click CSV export. These enhancements optimize workflows particularly when working with large instrument lists.

Asset management

B2CONNECT administrators are now provided with enhanced control over asset configurations with built-in safeguards to prevent deletion of referenced assets. This ensures system integrity while providing the flexibility to clean up obsolete or unused assets.

Resolved issues

Fixed an issue with trading parameter calculations for instruments with contract sizes. The system now correctly converts all trading parameters using contract size multipliers, ensuring accurate minimum order amounts, price steps, and notional values are communicated through the FIX SecurityList endpoint. This fix particularly benefits trading of derivative contracts where the underlying instrument differs from the quoted contract size.

August 29, 2025

New features

New docs section: Supported exchanges

With this release, we've introduced a detailed Supported exchanges section in our documentation, offering a comprehensive reference for each exchange our platform supports. This addition promotes clarity and easy access, allowing B2CONNECT users to quickly compare and reference available capabilities across exchanges at a glance.

Improvements

Explicit default STP setting

To prevent unexpected behavior and reduce reliance on exchange policy defaults, we now explicitly set a fixed internal default STP (Self-Trade Prevention) mode in our API calls. This ensures consistent and predictable trade execution across all environments, regardless of future changes by liquidity providers.

Resolved issues

There have been no customer-facing issues reported in this release.

July 31, 2025

New features

Granular asset management via Web UI

B2CONNECT administrators now benefit from enhanced control and efficiency in asset management with new export/import options integrated into the B2CONNECT Web UI:

Bulk asset export: Efficiently export assets to CSV for reporting or backup purposes, streamlining administrative tasks and protecting essential configuration data.
Bulk asset import: Effortlessly import multiple assets from CSV files, reducing manual entry, minimizing errors, and ensuring asset uniqueness through built-in validation rules.

Alerts system for swap charge issues

The system monitoring has been enhanced by implementing automated notifications for failed swap charges. These real-time notifications provide detailed explanations of failures, facilitating quick troubleshooting, and boosting system reliability. Common issues addressed include missing market rates, symbol data discrepancies, infrastructure issues, and internal errors.

Improvements

Enhanced compatibility with Binance

To ensure continued compatibility and accuracy, B2CONNECT services have been updated to align with recent changes in the Binance API. This enhancement makes certain that the minimum notional values provided through the B2CONNECT FIX API SecurityList endpoint are always accurate, preventing order rejections due to incorrect amounts.

Additionally, the Binance Spot adapter has been updated to meet the latest WebSocket API requirements, ensuring smooth order updates and improved platform reliability.

Advanced raw message logging

A significant enhancement has been added to order placement and execution workflow. A key point is the implementation of advanced raw message logging. This enables B2CONNECT to log all raw incoming and outgoing messages during its communication with a supported liquidity provider, thus enabling precise troubleshooting and rapid issue resolution at the LPs end.

Improved error handling

Another improvement in the order placement and execution workflow includes the refined logic for handling timeout errors. An order is now considered placed if such an error occurs, providing a definitive status and preventing uncertainty during order execution.

Rate limiting for reliable connectivity

The reconnect algorithm for a supported liquidity provider has been improved by integrating a robust rate-limiting mechanism. This enhancement caps the number of reconnect attempts to an optimal value, reducing the chance of IP bans and maintaining stable, uninterrupted connectivity.

Reduced trading service startup time

With this release, the bulk-load order event recovery mechanism has been implemented. By efficiently processing large volumes of order events during system startup, this update significantly reduces the time required to restore services after a restart or unexpected outage. As a result, traders experience minimal downtime, ensuring continuous access to the trading platform and improving overall operational efficiency.

Resolved issues

There have been no customer-facing issues reported in this release.

June 30, 2025

New features

Liquidity acquisition from multiple providers and its distribution to diverse trading platforms and market data consumer types.
Price feed across all asset classes, including forex, CFDs, indices, metals, and crypto (both spot and derivatives), accessible via both single or multiple connectors.
Uninterrupted liquidity with automated order routing based on symbol availability and robust failover policies.

Advanced spread control

B2CONNECT administrators can now precisely control the maximum allowable spread in order books, significantly enhancing liquidity and boosting trader confidence. They can set and manage maximum spread limits to avoid sharp market data fluctuations, and track anomalies through detailed metrics.

Symbol-based price invalidation

B2CONNECT introduces sophisticated symbol-based price invalidation to ensure price accuracy:

Web interface management: Configure, view, and manage price invalidation parameters directly through the Web UI.
CSV import: Import symbols via CSV files that include detailed price invalidation parameters.
Real-time logic: Implement comprehensive real-time price invalidation across all stages for consistent and precise quoting and trading.

Aggregated execution reports

Execution reporting now supports fill aggregation, optimizing reports for platforms such as cTrader. This feature consolidates multiple fills into a single, coherent execution report. B2CONNECT administrators can enable or disable aggregation settings to tailor reporting to the trading platform preferences. Alerts for overfilled aggregation scenarios provide timely insights for effective risk management.

Automated swap fee charging

B2CONNECT now streamlines swap charge management. B2CONNECT administrators can easily set up Swap Profiles and apply them to trading accounts. The built-in Swap Charges Planner helps schedule and run swap charges efficiently. Migration to an optimized Account Configuration system provides superior performance and reliability.

Improvements

Enhanced precision handling for FOK orders

Handling of Fill-or-Kill (FOK) orders has been improved to guarantee compatibility across all liquidity providers, even when the order amount precision differs from trading platform specifications.

Standardized order cancellation for Liquidity Takers

The order cancellation support has been improved for liquidity aggregators and other liquidity consumers, ensuring more responsive and reliable order lifecycle management.

Symbol integration into account configuration

Symbol management is now seamlessly incorporated into account configuration to maintain consistency across liquidity settings and to simplify administrative tasks.

Streamlined UX

These improvements feature a more intuitive color scheme and streamlined design, offering a modern and visually appealing interface. The user flow has been optimized, making navigation more straightforward and efficient. Additionally, component performance has been boosted, reducing load times and enhancing overall responsiveness for a better user experience.

Resolved issues

Fixed an issue where an order cancellation request might be mishandled if received before the system processed the initial order confirmation from a liquidity provider.

May 30, 2025

Improvements

Enhanced FIX API SecurityList endpoint

Improved the liquidity metadata handling to ensure that order placements, based on the liquidity parameters provided via the SecurityList FIX endpoint, are compatible across multiple liquidity streams.

This upgrade aggregates liquidity parameters for symbols across multiple providers, combining them into universally supported values. As a result, orders can be placed across several liquidity providers either simultaneously or in a failover mode, ensuring compatibility with all involved providers.

Improved handling of negative spreads

Enhanced management of negative spreads has been achieved through more efficient filtering of Level 2 quotes and incremental updates. This improvement targets asset prices that could cause negative spreads in liquidity distributed to trading platforms and other consumers via the FIX protocol. The newly updated business logic effectively and efficiently filters out such quotes to prevent the negative spreads from appearing in the distributed liquidity.

Enhanced resilience when processing fast subscribe/unsubscribe sequences

B2CONNECT FIX server can robustly handle fast subscribe/unsubscribe sequences by liquidity aggregators, even when these aggregators do not strictly adhere to the FIX protocol standard, reusing the same request IDs. The newly implemented algorithm reliably handles such cases, eliminating even the intermittent subscription failures.

Resolved issues

Fixed an issue, where orders were re-sent (placed again) if one of the supported liquidity providers returned an unrecognized error message. Such messages are now categorized under a unified system, resulting in conserving the API rate limits on redundant order placements and reducing the risk of IP bans.
Fixed an issue where, after replacing the API credentials of a supported liquidity provider with new ones, the system continued subscribing to the execution reports stream using the old credentials until restarted. This fix ensures that the credentials can be replaced live, without the restart of services.

March 31, 2025

New features

New integration with Bybit

B2CONNECT has launched a new adapter for Bybit, providing full support for perpetual futures contracts. This integration leverages B2CONNECT's robust infrastructure, allowing access to Bybit's market data and trading functionalities. It ensures seamless trading and quoting, enabling client platforms to offer advanced trading options and enhanced user experience.

This upgrade affirms B2CONNECT commitment to delivering cutting-edge liquidity solutions, ensuring clients always have access to the best available liquidity infrastructure.

Execution report deduplication: Logic has been added to effectively deduplicate execution reports from Binance Futures. This resolves issues caused by occasional duplicate reports originating from the LP side, ensuring accurate order state tracking.
Order state recovery rate limiting: A rate limiter has been implemented for requests related to order state recovery. This proactive measure prevents potential rate limit violations on the Binance Futures platform, safeguarding against temporary bans or request throttling during high-activity periods.

These updates contribute to a more robust and resilient integration with Binance Futures.

Resolved issues

There have been no customer-facing issues reported in this release.
