From the picture above you can see how I have managed to fit the MA in proximity of price in such as way that it provides to price dynamically. Dont bother which MA or what period is used, because the truth is next time it wont fit in as clearly as it does now. The important thing here is trail & error, the only way to find the dynamically fitting MA.
So secret technique I use is, I start with 25 period & then 30 period then 50 period then 50 period then 100 period on low in uptrend & high on downtrend, so on so forth with different numbers till I feel it dynamically supports or resists price from moving. So next time, be the little researcher yourself when you think of making use of MA & dont settle for famous 100/200 period or . Instead try to experiment & play with different period & different kind of MA & see how it fits into price of different pairs. Hope this information will help you & thank you for taking time to read this long.
