Re: Changing output from AMA

Sorry ... I forgot all about the DBS Lookback formula.

X:=Stdev(C,30);
Y:=Ref(X,-1);
Z:=1+((X-Y)/X);
If(Cum(1)=1,20,Min(Max(PREV*Z,20),60));

I guess that I could use it.

Best regards and Happy Holidays

Subject: Changing output from AMA


| Hi Adam and other formula writers
|
| How would I rewrite this AMA formula to output the number of days that the
| AMA is using rather than the AMA value for the tradeable?
|
| I want to use it in the following Stochastic formula to define the number
of
| days in Range:
|
| (Current Value - Low of Range)/(High of Range-Low of Range)
|
| Thanks for your help
|
| Best regards
|
