MAs are useful

someone said this ....
"The MA's are very powerful and I use them both in isolation and in combination with all my other stuff.

They tell you the trend in two time frames, where prices are in relation to the trend, the strength of the trend, are invaluable as support and resistance AND especially when they are in confluence with support and resistance levels and can give us an idea when to expect the rubber band move to come into play.

The cross of MA's, although never used as a trading signal due to the lag, is also very informative. Their slopes provide valuable information as they do when they "trap" prices between them.

Since they are also used by banks, funds, hedge funds, trading houses and large institutions they become "self - fulfilling" much like Fib levels and retracements."
