Dude, imo some of your support/resistance lines are a bit out, P&F is meant to be objective but your lines are learning towards subjective.
I have hacked your chart with my thoughts, hope you don't mind 😎
grey resistance line - fine
Brown resistance line - should ends in the same column as where the grey line starts (however it could have become possible support after this point)
pink support line - should end where aqua line starts (however it could have become possible resistance after this point)
aqua support line - shouldn't exist at all! it only touches twice on the bottom of a valid O column, and there are loads of other s/r line breaks happening in the middle
blue support line - fine
green trend line - I don't think you can call a trend on such a short timeframe of data
F2 I agree with what you say but I try and look for as many contact areas of the S n R levels in order to assertain their strength or not mand the project them through to the current time.
Red trend, agreed its far too weak but its where the new down boxes start.
green trend drawn cos its the second retest of that level, a strong signal imo.
