Could you translate this line into english.I'm having a problem
understanding it.
"pds:=If(pds>Cum(x<>-101)-VAvgPds,Cum(x<>-101)-VAvgPds,pds);"
It's the <> thats the problem.
I'm having a problem understanding the Cum function in the formula
you supplied for Volume Adjusted EMA. My english translation of it
is "If pds is greater than Cumulated value of (x (which is the Close
in this case)not equal to minus 101)minus VAvgPds then pds =Cum(x<>-
101)-VAvgPds else pds=pds. What are the <> doing there??
Thanks for your input up to this point Lionel.
