Are you able to explain the outcome?
As mentioned in another post you either end up buying the new "high" every time there's an uptick after the first "high" which is obviously rediculous, so you then have to specify when is the "high" that you're going to go with as the "high", which is usually contained within an arbitrary time window. So you end up with "buy the new high after 10:00am" or something similar which doesn't get you very far, since you only really know what the high for the day is after it happens and when it's too late! It is very educational being confined to a very specific criteria though since you end up eyeballing charts for a long time in between signals, you start noticing other patterns.

but not if you day trade GE or follow your (IBD O'Neil) 7-8% rule.
