Hey TP, I had put that box there on purpose because I posted it on other boards, But here I will tell you the Blue line is the 5ma the redline is the 10 ma and the green line is the 20ma. On a weekly chart the 5/10/20 moving average represents 5/10/or 20 weeks, not days.
On a weekly chart a 5/10 cross is a buy signal for me, obviously when the 5 crosses over the 10 upwards. When the 5 crosses 10 going down that is a sell/short signal. The 20ma acts as a support level, should the 5 or 10 break through the 20ma, than that indicates a true trend reversal, be it up or down, is in place.
On a daily chart, a 10/20 cross is what I use to determine future trend. The 50ma than acts as support.
The 5ma on a daily chart is used as a leading indicator, when it starts to turn in the opposite direction of the current trend, it puts up a lil warning signal that says "I need to watch this closely for a reversal"
I hope I explained that so you understand it, if you have any questions please feel free to ask.
