So something like this would be a good substitute If(H > Ref(H,-20)
,Ref(OPEN,+1),0) for Williams buy Stop. It gives next day OPEN when High
is higher that 20 days ago.
I believe it would be perfectly possible to include commissions into
your MaxLoss code, you could include it as a input.

My code returns the entry price (stop value).
Just substitute any entry of your own choosing, it doesnt matter. See
the gif in my previous post.
