for intraday trading, i would give 13,5,6 a try. much clearer and more precise. i used to use a 34 ema, but i found that to be insignificant compared to using a 5/13/20 sma setup. the 5 sma gives you a price guide. NEVER place an order far away from this line. always try to place an order at the line if possible (here's an example for you...take a look at a failed breakout vs. a successful breakout -- notice how the 5 sma 'guides' the successful breakout, whereas the failed breakout is far away from the 5 sma???) the 13 sma gives you an intermediate signal to the strength of the trend (again, take a look at the end of a trend and you will see how price starts to push through the 13 sma -- this is your signal to get out!), and often 'catches' price in a reversal (when a trend reverses, watch how price crosses the 20 sma and then comes back over and gets 'caught' by the 13 sma before thrusting in the new direction). and finally the 20 sma gives you a great confirmation indicator of the direction of the trend (although you should use the next higher timeframe for direction).
in the end, you will realize that it is not the system that gets you there, its your discipline to follow that system. YOU have to be able to TRUST your system. find something that you can trust -- something that seems 'clear' to you, and follow it religiously. there is no 'trick' or magic set of indicators to making money trading -- most new traders fail to ever realize this.
good luck!
