You can choose your Take Profit with the predefined +50%, +100%, +200%, +300% or type in your own value, this can be changed clicking the pencil icon under the `TP/SL` column once your position is opened.

The UI seems a bit slow since it needs to embed TradingView and there are some bugs that didn't render the JSON text properly in the info pop-up:
