Stop Loss

What is a Stop Loss?

A stop loss is a protective order that automatically closes your position when price reaches a predetermined level, capping your loss on the trade. It's your primary defense against catastrophic losses and the foundation of every risk management system.

For prop firm traders, stop losses aren't optional — they're survival tools. Without them, a single trade can breach your daily drawdown limit or even your overall drawdown, ending your challenge immediately.

Types of Stop Losses

• Fixed pip stop: A set number of pips from entry (e.g., always 30 pips) — simple but doesn't account for market structure
• Technical stop: Placed beyond a key level (support/resistance, swing high/low) — adapts to market conditions
• ATR-based stop: Uses Average True Range to set stops relative to current volatility
• Time stop: Exit after a set period if the trade hasn't moved in your favor

Common Stop Loss Mistakes

The biggest mistake is moving your stop loss further away when price approaches it. This turns a small, planned loss into an unplanned large loss. The second mistake is placing stops too tight — getting stopped out repeatedly on normal price fluctuations, then watching the market move in your original direction.
