[BUG] The tool is unable to place trades..

[bpawnzZ]

I have this tool connected and running and it works to query positions, pull ccandlestick data, and pretty much all market data you could want.. Only issue I'm having is it cant place or close trades! It give me a message that i need to enable auto trading. Algo trading is on and dll's are allowed and everything to my knowledge should be working.. Does anyone have a fix or a way to solve this?

Overall the tool is great. Just really need the ability to place trades. Am i missing something obvious or something i should already know?

Thank you for your help!

Hi @bpawnzZ can you show what happens if you asked AI to place a trade? Here's an example prompt: https://mcp-metatrader5-server.readthedocs.io/en/latest/getting_started/#example-placing-a-trade

Hi @Qoyyuum,

First off, thank you for creating such a badass MCP tool! This has been incredibly useful for algorithmic trading with MetaTrader 5.

I encountered the same TRADE_RETCODE_INVALID_FILL error mentioned in this issue when trading crypto on XBTFX. After some debugging, I discovered that different brokers support different filling modes (FOK, IOC, RETURN), and the default FOK mode wasn't supported by my broker.

I've submitted a pull request (#56) that adds automatic detection of the supported filling mode for each symbol. The fix:

• Reads the symbol's filling_mode bitmask to determine what the broker supports
• Auto-selects the appropriate mode (IOC > FOK > RETURN priority)
• Works universally across all brokers without breaking existing functionality

The PR is fully backward compatible - users can still manually specify type_filling if they want, but now trades will "just work" out of the box regardless of which broker someone uses.

Thanks again for this fantastic tool! Wishing you all the best.
