That's what happens when one thinks they know everything. Reading further down I see someone cleared up the difference in the two different methods. I've looked at that 4sma,9sma and 40sma combo mov.averages and can't for the life of me see any predictive value in it whatsoever. Just whipsaws in my eyes but what the hell do I know for sure anyways,lol........Don't know if you found that combo helpful. I do have a book called The Magic of Moving Averages that uses the 4sma,18sma and 40sma he calls the Delphic Phenomenon. In real life it isn't that great either most of the time. But the one thing I have found very useful in that book is when not only those 3 mov.averages converge into a tight band, but any combination of moving averages that converse like that you will see prices flip out and move sharply one way or the other almost invariably. Check out some charts with most any combination of similar mov.averages to see this. That would be the time to put option Strangles on that market each time to catch the big surprising move either way. They are explosive as a rule and do catch most by surprise.
