50 Day EMA/100 Day EMA Crossover Time

[Palm]

Hefi,

Will try my hand at it.  the 50-day crossing the 100-day ("Golden Cross" on the upswing is very bullish and lets you get in on the momentum earlier; it's actually a buy signal and tends to signal a nice ride up, then you can use the opposite (when the 50-day crosses the 100-day on the way down) as a sell/trim indicator.  Using the 200-day gets you in too late in the upswing.  If this link works it shows you IOC over the last 5 years and you can see the pattern:
