not quite aware about the exit plan, but never thought breakout system would given any good result, on Oil price are no exception. it's a common use trading method, unless you're willing to share more detail information upon these method .
are these manually trade or automatic one ? as long as it's not martingalish one I'd gladly to give it a try.
as for now I use partial close combine with lock profit as exit method. for example when I use 100 lot at specific pips gain it took half lot size and closed. and for the rest use trail to prevent losign pips gain.
these are not martingale one, no worries. unfortunately these system are under forward tested performance with several account, oil price only, including WTI at tickmill. and seem I dont have obligate to share any trading system since these board also has commerce section. found several case at ff when people got kicked to comm section while having share their trading system at public section.
