MetaTrader

MetaTrader Development — MT4, MT5 and MQL

Expert advisors, indicators and MetaTrader integrations.

MetaTrader remains where a great deal of retail and prop FX execution happens. We write MQL properly — with error handling, state recovery and a test harness — rather than shipping a file and hoping.

What this covers

MT4 and MT5 expert advisors written to survive restarts and reconnects
Custom indicators and trading panels
MT4 to MT5 migration and MQL to Python conversion
MetaTrader connected to Python research and risk systems
