I will attempt to impart some knowledge on you in terms of reversals.
First of all let me give you a few tips on the SPY:
SPY's are tough, as the S&P futures are controlled by locals
( pit traders ) and they are not a weak bunch. Shorting breakdowns and playing obvious setups are tough. With the SPY's you need to do your work ( charts ) and trust support and resistance and set stops that are not obvious. If you plan on trading these you must be smarter than the average trader as the best moves come of fake breakdown and breakouts. One suggestion, use stochastics on a short term chart 3 or 5min and when you see weak highs being made or weak lows then you can take a shot at a fade play.
Now, as far as reversals, I believe the best way to play reversals is waiting for the confirmation of a double tops and bottoms. These occur everyday in many stocks. They require patience as you must take a little higher entry than you may like off double bottoms and lower than you may like of double tops but waiting for the confirmations will set you up for gains more often. For example, watch a low, then bounce, a retest low and buy when the bounce high is broken. The logic here is as follows, after the low is made short sellers move in and start shorting the bounce, as the stock moves back to the lows short sellers with profits move their stops to break even ( high of bounce off lows ), now as the price breaks above this on the bounce off the second low shorts are forced to cover thus pushing the stock up and bringing in buyers that see the double bottom form. I will give you an example on the SPY:
5 minute chart from 1/31, look at the 14:00 bar low of 112.18 (valley #1) , 14:25 bar high 112.69 (peak#1), 14:50 bar low of 112.22 (valley #2), now entry is taken once 112.69 is broken. This occurs into the 15:05 bar and continues higher into the end of day. check also the action between 12:30 and 12:50.
You must set your own stops and targets, but add this to your arsenal. Hope it helps.
