A stop-loss is the price at which you accept the trade was wrong and get out. A target is where you plan to take the win. Both are decided in advance, which is the entire point — decided afterwards, they are just feelings.
Setting them before you enter
When the full order ticket is open, fill in Stop loss and Target before pressing PLACE. Use the percentage presets (0.5%, 1%, 2% for the stop; 1%, 2%, 4% for the target) or type an exact price. The presets are measured from your entry price.
Setting them once you are in
The position bar carries the same controls: an SL group and a TP group, each with presets and a price box. Tap a preset or type a price and it applies immediately. The bar shows your live stop and target next to your entry and the current price, so there is never any doubt about where you get out.
Trailing the stop
TRAIL SL (or T) turns on a trailing stop. It follows price in your favour at the distance your stop is currently set, and it never widens. Turn it on once a trade is working and it locks in gains without you having to watch every bar.
What happens when one is hit
If a candle trades through your stop, the position closes at your stop level (or the candle's open, if it gapped past it). Targets work the same way. The exit is logged with its reason, so your journal shows whether you were stopped out, hit target, trimmed, or closed by hand.
