The concept that trips up most newcomers is position sizing & risk‑per‑trade. Many think “a lot of pips = big profit” and ignore how much of their account is actually at risk. The rule of thumb is to risk no more than 1‑2 % of your account on any single trade. Calculate the dollar risk (stop‑loss distance × lot size) and adjust the lot size so that this equals your risk budget. This keeps drawdowns manageable and helps you stay within prop‑firm daily loss limits and consistency rules.
Why it matters: Prop firms such as *The5ers* (code BRIDGE) or *FundedNext* (code BRIDGE) enforce strict daily loss limits. Oversizing a position can trigger a breach even if the trade looks good.
How to apply: If you have a $10,000 account and risk 1 % ($100), and your stop is 50 pips away, your position size should be $2 per pip (100/50). This may mean trading micro‑lots instead of standard lots.
Limits: Position sizing does not guarantee profit; it only controls risk. Combine it with solid entry criteria and a clear trading plan.
