MetaTrader 4 & 5
MQL4 and MQL5 bots connected via the broker's native MT server. We handle tick subscription, order modification latency, and the Friday session close behaviour that catches many automated strategies off-guard.
Broker Integration
Is Your Bot Actually Talking to Your Broker Correctly?
We test, certify, and deploy API connections between your trading bot and your broker — so order routing works precisely as designed.
Why Broker Integration Deserves Dedicated Attention
The gap between a bot that runs correctly in backtesting and one that performs consistently in live trading often comes down to the broker layer: rate limits on the API, fill behaviour that differs from the simulation, instrument naming mismatches, and session cut-off times that the backtest engine ignores. Sterling Atelier maintains a tested integration library for MT4, MT5, Interactive Brokers TWS, and three EU-regulated retail APIs commonly used by Romanian and Central European traders. Before any live capital touches the system, we run a minimum 15-session paper-trade certification using the exact API endpoint your live account will use.
Supported Platforms and What Integration Covers
We document every quirk we find so you're not surprised post-launch.
Interactive Brokers TWS
TWS API integration with proper handling of IB's pacing limits, re-authentication on session restart, and multi-currency margin accounting. Tested against IB's paper trading environment before live certification.
EU retail APIs
XTB, Admirals, and eToro's REST APIs are in our certified stack. We document rate limits, websocket reconnect behaviour, and instrument identifier formats so your bot handles disruptions gracefully.
