Hi, the pre-defined stop loss feature is not included or advertised on the product page for the % position size buttons, the only method to set a stop loss and take profit is with the manual buy and sell buttons with pre-defined position size.
Position size calculation
This tool offers Automatic Lot Size Based on Account Balance & Margin, with a simple key press you can decide how much you want to risk, taking into account your leverage. You also have the option to set your own % instead of using the preset buttons.
Trailing stop loss feature
The tool has an automatic trailing stop loss feature triggers when the trade is in profit, so if you set their value to 10, then you will need to gain 10 pips in profit before it is activated for other symbol shown on the form, you can find more information on the product page.
