What’s a good candlestick pattern to use on when to exit?

Hi all;

I have come up with a pretty good system to determine when a stock is on a real rise. It's not 100% (what is?) but it's much better than 50%. It's based on changes in volume, moving averages, and a couple of other things. But the bottom line is – it's a good indicator.

What I'm struggling with is, what should I use to exit? I'm guessing some candlestick pattern but a lot of what I read on these is patterns that are used around small price changes. What is good for when a stock clearly has momentum going up?

thanks – dave

ps – If this is the wrong forum for this question, please let me know which is correct (this is not should I but stock X, it's how to determine when to sell any stock).
