To use the FXT Trade Manager simple function, check out the below video.
The simple trade manager allows you to select the lot size, the SL points (distance away from the entry in points) as the stop loss level, and TP points (distance away from entry) as the take profit level.
You will see the levels visually on the chart and the profit and risk will adjust in the display panel before you enter the position. Once the trade is at the risk and targets you want, you can press trade.
Trading with the simple trade manager makes it easy to adjust and visualize your trades without needing to calculate everything before hitting the button on your trade and having to adjust after the fact.
