TradingView Alert Fired but MT5 Did Not Trade: What to Check

Troubleshoot a TradingView alert that fired but did not execute in MT5: test the signal receiver, EA status, broker symbol, MT5 log and webhook JSON.

Setup and test checklist

Use an MT5 demo account and keep Signal2Trade and MT5 running.
Send internal and public test signals and confirm both appear in history.
Confirm the EA is attached, online, and permitted to trade.
Read the MT5 Experts log and match the TradingView symbol exactly to the broker chart symbol.
Only after client and MT5 tests pass, recheck the webhook URL, port 80, and Alert Message JSON.
