here, i'll give you a chunk of my system.
buy/sell tight consolidation breakouts or retracements of strong/weak stocks intraday.
sell/ buy stocks that are really far stretched up / down intraday.
now, if you use it, you'll probably go belly-up, and blow out either holding a 'strong' stock that doesn't act right, or selling a strong stock that keeps running.
there's so much more to it than just that.
by the way, the specifics? and the other chunks of my system? not a chance. it's worth more to me than a person could pay.
