Why isn't my EA placing trades?
Diagnostic sequence:
1. **AutoTrading state** — the button in the main MT5 toolbar must be green. If red, click once. 2. **Smiley face** — top-right corner of the chart. Smiling = OK. Sad = algo trading disabled for this EA. Right-click the chart → Expert Advisors → Properties → Common tab → tick "Allow Algorithmic Trading". 3. **Trading hours** — open the EA inputs. Most EAs have `StartHour` and `EndHour` (broker server time, not your local time). The current server-time clock is in the Market Watch panel. 4. **Symbol** — make sure the chart symbol exactly matches the EA's expected symbol. Some brokers add suffixes like `XAUUSD.r` or `XAUUSDx`. Switch chart or set the EA's `Symbol` input. 5. **Logs** — the Experts tab in the Toolbox shows the EA's runtime log. If the EA is rejecting setups it will say why.
