  2. 16:11Room 466 USD, inside the 500 USD margin. Rule Guard closes the positions it opened and locks the day until the reset.

Times are server time. Live, Rule Guard reads equity on every tick, so new trades wait as soon as the room reaches 1,000 USD. Margins shown are the defaults: 0.5% of the start.

What it does.

Floors calculated the way your firm does.

The daily floor uses the start-of-day balance. The total floor uses the starting balance or the peak. The day resets at the firm's time.

5% / 10%

No new trades near the floor.

At twice the safety margin, Kalibre Engine opens no new trades. At one safety margin, it closes its own positions.

Firm presets.

FTMO 2-Step, FTMO 1-Step, FTMO Instant and The5ers High Stakes, or your own limits. FundedNext and FundingPips are planned.

Does my firm allow EAs?

Check your firm's rules on EAs; some firms restrict them. Rule Guard runs as an Expert Advisor in MT5.

Can it stop trades I open by hand?

No. It counts positions opened by hand or by another EA when it works out the remaining room, but it cannot block those orders.

Does it guarantee that I pass?

No. It watches the loss limits only. Slippage and price gaps can cause losses beyond a stop.

Is Kalibre a prop firm?

No. Kalibre is not affiliated with any prop firm. Firm names are used only to describe their rules.
