Amitman,
Sorry to hear you've had a bad period.
I don't know if this will help, but here's what I see from your post...
If you're getting 5 winners out of 7 trades and losing money it says two things:
1) 5 winners out of 7 says the method you are using works
2) losing money on that performance ratio says the math is wrong
If you are using a 20c profit target (which, in my view, is about right for those stocks), and your stop gives you 1:1 R/R, and this becomes 2:1 R/R with commission etc, your commission is too high proportionately for the trade size, and/or your slippage is too high. You don't break them down, so it's not clear which, or both. At those ratios, it sounds like you may be trading lots which are too small for the method. I wouldn't ask what size lots you trade, but for example, $5 commission on 1000 shares x 20c is very different from $5 on 100 shares x 20c. If that's where the problem lies, you need bigger lots, or a bigger timeframe -- $5 on 100 shares x $2 is OK, too...
Ref: "I still scalp AMZN and RIMM but I'm starting to think that with my profit targets (20-30 cent) these stocks are just to fast for me."
I trade similar stocks to you, with similar stops and targets. I'm sure these stocks are not too fast for you -- they may just be too fast for your current execution method. I don't know if you are familiar with any of the third-party execution systems, but I use NinjaTrader -- here's a couple of things which may be relevant to your post: you can set up Stop Limit orders in advance -- eg limit is 5c above stop for long entry. You can also set up simple strategies in advance, where stop loss and profit targets are set as soon as you are filled, at levels you set up in advance. Once those parameters are set, you can place the order very quickly with one click on a chart -- this is how I do it, I get filled pretty much every time, and at decent fills. With a 5c limit above stop, I can still use a 20c target.
I think you're dead right about scaling out, too. My experience has been the same. When you look back at charts it looks like a bigger target would get hit, but in practice I found that after exiting half and moving the stop to B/E, most often the second half of the position fell back and stopped out.
I would say, don't get discouraged -- 5 out of 7 is great going, (as long as your losers are not too big...).
