I got burned too many times buying the breakout. If I see it early enough I will buy with a trailing stop but my main focus is watching for consolidation after a top and then buying with the next volume/price increase, initially with a tight stop that gets moved up once I am solidly in the green. That's the easy way to trade a breakout. It is easy to catch it with your scanner on the first big push, and easy to get set for the second push. If it looks strong enough I will ride out the next consolidation and then sell after the third top or at a potential line of resistance such as an even dollar amount or a recent high or repeating high or the top bollinger widened out to 2.2 std. deviation. Or a doji that looks like a possible reversal. Anything that tells me that maybe it's done and getting overripe. Letting the breakout settle and catching the next push misses out on a lot of potential profit but it is a little safer and easier to catch in time to do some good.
Like deaddog said, a lot of really strong breakouts are plays in one act, and they top once and that's it. Doing it my way of course misses all of those but it just works better for me. There will always be another trade and since it isn't my full time occupation, I can afford to miss out on trades, and I have been under the PDT limit most of the last 12 months anyway.
