DAX M15 long wave diver with grid and MTF

Hello, I want to introduce you to one of my works. I hope for numerous comments and for one or the other idea whether there is still room for improvement.

The system traditionally acts as a setback in the upward trend. Doubled over a grid with greater loss, but is capped at a maximum of 3 positions. So quite risk-free.

I also added a multi-timeframe, but only to get even better results with the trailing stop.

I have been trading a similar system in the H1 for a long time, with great results.
