Take profit and stop loss, explained

Setting exits before you enter: ROE vs. price %, risk/reward, and the mistakes that cost the most.

Key takeaways
  • TP and SL close your position automatically on the server — even when your browser is closed.
  • Levels can be set by ROE % or by price %; at 20× a 1% price move equals 20% ROE.
  • A 1:2 risk/reward lets you be wrong more often than right and still come out ahead.
  • Keep the stop loss well before the liquidation price.

Every trade has two possible endings you can plan in advance: the price reaches your target, or it proves your idea wrong. A take profit (TP) closes the position automatically when the price reaches the target. A stop loss (SL) closes it when the price reaches the level where you accept being wrong. Both are checked on the server, so they trigger even when your browser is closed.

Setting levels: ROE % or price %

The TP/SL window lets you set levels in two ways. ROE % is the return on your margin; price % is the move of the market price. With leverage they are linked: at 20× leverage a 1% price move equals a 20% ROE. Choose whichever you think in — the window always shows the resulting price, the ROE, the price change and the estimated P&L side by side.

Long at $2,684, 20× leverage, $200 margin
TP at +5% price$2,818 · +100% ROE · ≈ +$200
TP at +50% ROE$2,751 · +2.5% price · ≈ +$100
SL at −2% price$2,630 · −40% ROE · ≈ −$80

Risk/reward

Risk/reward compares the distance to your stop with the distance to your target. A stop 2% away and a target 4% away is 1:2. The ratio matters more than how often you are right: with 1:2 you can lose six trades out of ten and still finish slightly ahead. The window shows this ratio as soon as both levels are set.

10 trades, risking $20 each
1:1 · 5 wins, 5 losses≈ $0
1:2 · 4 wins, 6 losses≈ +$40
1:3 · 3 wins, 7 losses≈ +$40

Where to put the stop

  • Below a recent swing low for a long, above a recent swing high for a short — where the idea is clearly invalid.
  • Far enough from the entry that normal noise doesn't hit it. Look at how much the price usually moves on your timeframe.
  • Well before the liquidation price. If the stop sits beyond it, the position is liquidated first — the window warns you about this.

When markets are closed

For stocks, indices, forex and commodities, TP and SL are checked while the market is open. If the market reopens beyond your level after a weekend or overnight, the position closes at the reopening price, which can be better or worse than your level.

Common mistakes

  • Moving the stop further away once the trade goes against you. It turns a planned small loss into a large one.
  • Targets so close that fees take most of the profit.
  • No stop at all on high leverage — liquidation then becomes the stop, and it costs the entire margin.
  • Setting exits after entering, when it is harder to stay objective.
Decide your exits before you click Long or Short. Emotions are quieter before the position exists.

FAQ

Can I change TP or SL after opening?

Yes. Use the edit button next to an open position or pending order.

Is a TP/SL guaranteed to fill exactly at my level?

It triggers when the server price reaches the level and closes at that live price. In fast or gapping markets this can differ slightly from the level.
