Thanks for your comment TF. Use it as a confirmation means you will enter or exit a position based on other signal or condition, and MAcrossover is only one of the confirmation/condition that support your decision. Is it right? But what I see from monthly chart, 9/21 MAcrosses are least frequent, then...weekly chart crosses, then daily, then 4or1 hourly, the shorter the time period the more fluctuation or double cross it happen, but with analysis or combination of all the four time frame MAcrosses, maybe we can come up with a higher probability winning entrance. I quote an example, whenever the MAcrosses happen in narrow trading...then the narrow breaks...and the upcoming cross are noticeably distanced from the prior one, at this point, this cross usually has a good or better probability, right? Is it possible to use MAcross as the key condition, and combine w/ others such as RSI, MACD, ROC, stochastics...etc.
Is it a common thing if the EA composed of 3~11 conditions/signals? and not just MAcross alone..right?
