Quote from spike500:
The fact that you have to use different settings depending on the item you trade leads to the following conclusion:
3MA's are worthless because you have to optimize them to get returns. Take another period for the same item and you will have to optimize again. You will always be running behind the facts and always be too late.
MA's are only valid in the long run and to take parts of the big trending moves. They are not very efficient.
I am not sure of what you mean by "optimize".
i disagree that moving average are only good in the long run...
here is a graph of QQQQ with a very short term moving average. 1-3-5 day. If i change that to a 7 20, 90 day moving average, the trade becomes unprofitable.
sorry for the bloomberg in spanish....
