Re: use IF statement, return nul value

John:

My mistake.
 
This trick is only good to prevent indicator being plotted BEFORE a
certain user define nos of days -D- from the beginning of the chart, but
not after.

Eg: late Start 3 EMA

days:=Input("StartDays",1,5000,50);
launch:=Cum(1)>days;
Id:=Mov(C,3,E);
If(Cum(1)>launch,id,RSI(days+1))

I realise this may not solve your problem, but maybe you can explore
from this direction :).
