Risk limits for master traders

To control losses on copy-trading and MAM master accounts, assign one or more risk limits. When any limit is reached, all open positions are closed, all pending orders are canceled, and the account is blocked from further trading.

Risk limit	What it caps	Unblocking
Daily risk limit	Maximum loss within a single trading day	Automatic, at the next day’s start (MT server 00:00)
Loss limit	Maximum loss for all time	Manual, in the Back Office
Maximum Drawdown limit	Maximum Max DD, as a percentage	Manual, in the Back Office

Back Office only

Risk limits can be assigned to master accounts only in the Back Office.

Daily Risk Limit

The maximum loss allowed in one day, set either as a fixed amount in the account currency or as a percentage of the equity recorded at the day’s start (recalculated daily).

As a Fixed Amount

Equity threshold = Equity start − Risk limit value

Example:  1,700 − 100 = 1,600  → account blocked if equity reaches 1,600

As a Percentage of Equity

Equity threshold = Equity start × (1 − Risk limit %)

Example:  1,700 × (1 − 0.1) = 1,530  → account blocked if equity reaches 1,530

After a Deposit or Withdrawal During the Day

DW is the net of balance operations during the day (withdrawals negative, deposits positive). The threshold is recalculated:

Fixed:       Equity threshold = (Equity start + DW) − Risk limit value
Percentage:  Equity threshold = Equity start × (1 + DW / Equity start) × (1 − Risk limit %)

Example (withdraw 200 from a 1,700 start):
  Fixed (limit 100):       1,700 − 200 − 100 = 1,400
  Percentage (limit 10%):  1,700 × (1 + (−200/1,700)) × (1 − 0.1) = 1,350

Loss Limit (Maximum Loss)

The maximum trading loss allowed for all time. The account is blocked when:

(Realized PnL + Floating PnL) < Loss limit value

Example:  200 − 551 = −351 < −350  → account blocked (manual unblock only)

Maximum Drawdown (DD) Risk Limit

Max DD > Max DD limit value

Example:  limit 20% → account blocked once observed Max DD exceeds 20%

Setting the Max DD limit

You can’t set a Max DD limit equal to or below the account’s current Max DD. If the current Max DD is 20%, the limit must be above 20%.
