[jago25]

And there's trendlines

and this based on Steves cool utility:

But what I'm looking for is something for the assistance of creating time zones where a trade must take place in. Ideally this would be like on the right in this picture but in reality I think the left hand has to be a better goal.

It would also be good to have it calculate position sizing and TP and SL zones in the same manner... this is because I tend to trade CFDs now more than forex and it's a bit of work to do the calculations... with typo risk ... it sounds like a difficult ask. Perhaps it exists....

I'm posting in general because I would be prepared to change platform for this...
just knowing the best terms to google for would be a great help!

edit: add a picture!
