For all you arrows users (Investools or Success): I buy with three greens and it's amazing how many times I regret it when i jump the gun and buy with two. So three green.
And I get out when the stock stops going up and I get two reds down below.
For all you non-arrow users who are trying to do the same thing using MSN charts: Set the MACD to 8-17-9 and the Stochastic to 14-5-0 and the Moving Average to the 10 day. You'll get triggered a little earlier than on Investools, but that's okay. The trigger point - the time to buy or sell - is when the lines cross. It ain't as easy and it ain't as purty but she works just fine once you get the hang of it.
