Not quite, though that could also be used as a breakout signal (IMHO).
The level to break out above is determined by the following pattern in 5 (or 6) consecutive bars
where HH means "highest high in this pattern", and H means "high that is lower than the highest high
in this pattern".
The 5 bar pattern is H, H, HH, H, H.
The six bar pattern is H, H, HH, HH, H, H.
I leave the coding over to you.
Of course there are filters to be applied as well.

Yes it is possible to include commissions, and I think I have posted an example. Where it starts to
get difficult is when fixed commissions are used with compounding equity. As I never bother now with
compounding equity this is not an issue for me.
