Auto Ma Period

[Samuel Cardonis]

hi

it is well known that in each time,

there a different period of moving average that

show the market behavior the best way,

this ma look like a trend-line in a trendy market.

the problem is that the period of the moving average has to be cange from time to time.

does anybody know an indicator that chages the period according to the market behavior?

for example,

when the ATR is high, the ma period will be smaller

when the ATR is low , the ma period will be bigger
