PropFirmGuard (free version)

Equity guard for MetaTrader 5 that enforces a daily loss limit and a total drawdown limit, flattens the account on breach and blocks trading until the next daily reset. The expert opens no trades of its own: it is a protection layer that runs on a spare chart next to any strategy or manual trading.
