Update: Splitted the strategy into two versions, one on 8.00-14.30 with 2.4 spread, and another on 14.30-21.00 with 1.6 spread.
Boxsize, renkotipe, sl, tp and bullish/bearish conditions optimized for both. Results in the images. Position size=0.5
I know that this could be highly overoptimize, but splitting the strategy for the different time ranges could be an idea to better perform following the spread.
You can see the non-splitted version on 2.4 spread on the right
