[3. Use] How do I change the SL/TP and Range Bar size settings?

In the strategy Start_ScalpingAI_EN on the M1 chart, you can choose between two predefined Range Bar size settings: Speed Scalping i Tactical Scalping.
SL and TP are automatically calculated as multiples of 5 x the size of the Range Bar.
In the future PRO version, it will be possible to change these parameters freely.
