Hi eagle...As far as the 15 and 50 Moving Averages...
First I always use Simple Moving Averages, as I have found them to be more accurate predictors...Others may disagree, but that's just 'my' style...
I use them because they are fairly 'Standard' numbers...
Include the 200MA in that combination, and that is the usual set up...
And yes, when the 15MA crosses up through the 50MA, I use that as a 'BUY' signal...Even more powerful is when the 50SMA crosses up through the 200SMA, and that is called the 'Golden Cross', and is a VERY Bullish 'Buy' signal...
I'll take a look at the Board you mention, and may drop an idea of mine in from time to time...
BTW...Look at the post I put up for RBAK on this Board yesterday...On the second chart, I said that 13.40 was the potential upside for today, and that overall the charts were Very Bullish...RBAK hit an intraday high of 13.43 today...It's struggling a bit now, but it needed to cool off for a while after running so hard lately...
Laters,
