Compiler Fixes
Fix unsupported filling mode without guessing FOK, IOC, or RETURN.
Unsupported filling mode means the order filling policy does not match the current symbol or broker account. Hard-coding a filling type can work on demo and fail on live.
Search intent
The EA or Python MT5 integration gets unsupported filling mode, invalid fill, or retcode 10030.

Let the symbol choose when using CTrade
For CTrade workflows, SetTypeFillingBySymbol reads the symbol settings and sets a compatible filling policy.
Read SYMBOL_FILLING_MODE for manual requests
For MqlTradeRequest, inspect allowed filling flags and choose a supported policy before OrderSend.
Compare demo and live conditions
A broker can allow different execution policies by account type or symbol suffix. Record the account, symbol, and filling flags.
Use the tool
Paste the trade request into Workfusion Debugger to add filling-mode detection and a safer CTrade setup.
