The daily loss cap that survives a restart.
VigilDesk Guard Free is a small Expert Advisor for MetaTrader 5. It watches your account against a daily loss cap and speaks up before the day is gone. The state is written to disk, so closing the terminal, restarting the EA or reinstalling MT5 does not hand you back the day's risk.

Pure MQL5 · no DLL · no network calls · no account data stored · source (.mq5) included ｜ 纯 MQL5、无 DLL、无联网、含源码
What it does ｜ 它做什么
Daily loss cap
Default 1.5% of the balance at the start of the broker's trading day. When it trips: alert, optional mobile push / email, optional close-all, and the rest of the day is blocked.
日内亏损上限（默认余额 1.5%），触顶后当日封锁。
Restart-proof state
State lives in the terminal's common folder, keyed by account number. Restart the terminal, the EA, or the whole PC — the cap does not reset.
状态落盘（按账号区分），重启不清零。
Per-trade risk warning
Recomputes the risk of your open positions against a budget (default 0.5% of balance) and warns you when a single trade is over.
单笔风险超预算即预警。
Early warning at 70%
You hear about the cap before it is gone, not after. On-chart panel shows used / remaining / state.
用到 70% 就提醒，图表上有面板。

What it cannot do — by design ｜ 它做不到什么
It is an Expert Advisor: it lives inside MetaTrader. So it cannot:
- restart your terminal after a crash or a hang — if the terminal is dead, so is the EA, and your positions sit there unprotected;
- watch several accounts from one screen;
- review an order before another EA or a Python strategy sends it.
Those three need a process outside the terminal — which is exactly what the VigilDesk desktop workstation does: a watchdog that relaunches MT5 and restores state, a risk gate that reviews orders before they leave, and an AI confirmer with a decision log.
