can anyone give me a hand with this??
My questions are regarding the AMA function of Amibroker. I'm trying to migrate an AFL script to Metatrader and need to code this formula.
1. the array "Period", where does it come from?
2. the "Factor" is calculated as 2/(Period+1). So is this a "fixed" formula or does it vary? If I would like something like AMA(Close, 0.5) where does the 0.5 gets plugged in the "Factor" formula?
3. How is the first value of AMA established?
Thanks for your help!
