Difference between iMA valu and moving avergage on chart

[omidgold]

Hi

i have a problem . i calculate iMA for a chart and simultaneously i check that value with moving average indicaator on chart. but they have different value. why ?

Why

not edit the standard script
Why write your own
Why do you expect the same value.
There are a lot of why to your question.
