Split your entry up into several smaller pieces, for example 3 limit orders, @ -1, 0, and +1 pips away from Dale's level.
I don't know how that would affect profits over the long run, but it should reduce frustration and spare you a little psychological energy.
It will take a fair amount of testing and study to come up with the optimal solution, perhaps even it is for the best to let the ones that turn a bit early go?
It is clear the level's Dale provides us so generously are significant points in the market. How to trade them optimally(only take the winners... close at the peak of the retrace... do so with maximum leverage... aahh the dream ) is not an easy question, but there is clearly a lot of room for profits in the space between the theoretical ideal and break-even trading.
EDIT: should probably add a sig in regards to this... I am a novice trader (about 2 years since I first looked into it, maybe the equivalent of 8 months full time work at this point), I currently trade with minimum order size to keep risk to a minimum, and I have yet to make more than a couple % on my risk capital. (And yeah, that is ignoring the $500 I blew in the account I opened 2 years ago convinced I was gonna be a millionaire by the end of the year )
Novice trader, please take my opinion with several grains of salt
