The steps to accomplish that are:
- Have at least one open trade
- Press Partial TP button on the device; a panel and a magenta line will appear on screen
- Press Target @ 1:x and the magenta line will move exactly to 1:1 RR
- Press the green Set button on the panel
Now the magenta line should be not editable and the partial trigger is acrive.
How to close 50%?
From the EA parameters, there is one parameter relative to the default % to close, which is by default set to 50% already.
Each new partial trigger will be set to 50%. If you need to change the percentage on one of the triggers, edit it from the panel.
How to use Target @1:x?
By default Target @1:x is set to 1:1. You can change it from the EA parameters. Every time you press it, the active tool gets modified accordingly.
