Gardien Prop Firm Guardian

Most prop firm challenges are not lost by a bad strategy. They are lost by one bad day: a trade without a stop, a revenge trade, an Expert Advisor that keeps opening positions after a losing streak. Gardien watches your whole account and steps in before a rule is broken.

What it does

• Daily loss limit, measured from your firm's daily reset hour (server time), as a % of the initial balance or of the day-start reference (balance, or the highest of balance and equity at the reset).
• Max loss limit: static (from the initial balance) or trailing (from the equity peak or the balance peak), with the option to stop trailing at the initial balance.
• When a limit reaches 90 % (adjustable) it closes all positions, deletes pending orders and locks the account: anything opened afterwards, manually or by any Expert Advisor, is closed at once. The daily lock ends at the next reset; the max loss lock stays until you clear it.
• Early warning at 70 % (adjustable), warning for positions without stop loss, and a "worst case" warning when hitting every open stop would break the daily limit.
• Profit target progress and trading-days counter. Optional: close everything and lock when the target is reached, so a passed challenge cannot be ruined.
• Optional high-impact news filter (MetaTrader 5 economic calendar): positions opened in the minutes around the news are closed; optionally also the ones already open.
• Optional Friday close for firms that do not allow holding over the weekend.
• Popup and push notifications to your phone.
• Locks, peaks and the day-start reference are saved: they survive a terminal restart.

A panel anyone can read

A large coloured sign tells you, in plain words, whether you can trade: YOU CAN TRADE (green), CAREFUL (orange), LOCKED UNTIL TOMORROW / LOCKED (red), NOT PROTECTING (red: Algo Trading is off), TARGET REACHED (blue).

Coloured bars show today's loss, total loss and the target, each with a white mark where the automatic close happens, and a sentence such as "You can lose 420.00 USD more today before the auto-close". Technical details are one click away. Panel in English or Spanish.

How to use

1. Open any chart (one without another Expert Advisor) and attach Gardien.
2. Allow Algo Trading (button in the toolbar and in the Expert Advisor settings). Without it, Gardien cannot close anything; the panel shows NOT PROTECTING.
3. Enter your challenge's initial balance, limits and daily reset hour (server time). Example: if your firm resets at midnight Central European Time and your broker's server is two or three hours ahead of GMT, the reset hour is 01:00.

Gardien only needs one chart to protect the whole account.

Important

• Gardien never opens trades on a real or demo account. In the Strategy Tester it opens sample trades (with stop loss) only so that you can see the locks working in the free demo; this can be turned off.
• It checks every second and on every tick, but a price gap (weekend, news) can move equity past a limit before any close is possible. That is why it acts at 90 % and not at 100 %. No tool can guarantee that a limit will never be exceeded.
• MetaTrader 5 does not allow an Expert Advisor to prevent other programs from sending orders. While locked, Gardien closes every new position immediately, which costs the spread.
• Every firm has its own rules and they change. Check your firm's current rules and set the inputs accordingly. Gardien is not affiliated with any prop firm.
