Stop-loss is used to close a previously opened trade at a price that is less advantageous for the customer than the value at the time the stop loss is placed. A stop-loss might be a simple limit you place on your order. Your order will be closed if this limit is reached. Please keep in mind that once you’ve set stop/limit orders, you just need to leave specific distances from the current market value. Please see the limit and stop levels for further information on the points gap for each currency pair.
If you want to limit your losses when the market goes against you, you should use a stop loss.
On BUY, stop-loss points are always placed below the current damage, and on SELL, they are always set above the current ASK price.
