Prop firms hand you a normal platform login — MetaTrader, cTrader or Match-Trader. Connect it exactly like any other account. What changes is the risk configuration.
Map their rules onto your settings
| Firm rule | Set this |
|---|---|
| Daily loss limit | Daily drawdown limit, at roughly 60% of their number |
| Total drawdown | Max total drawdown, again with headroom |
| Max position size | Max lot size per trade |
| News or weekend restrictions | Trading-hours window and news blackout on every linked channel |
| Consistency rule | Lower risk per trade, so no single day dominates |
Why the headroom
The firm measures on their server, in their timezone, including swap and commission. You measure on yours. Those numbers are never identical, and the gap is widest exactly when the market moves fastest. A breach at your limit is a pause; a breach at theirs is a dead account.
Set your daily reset time to the firm's server reset, not your local midnight. Floating loss counts at most firms, so a position left open across the reset can breach the next day before you wake up.
