Thanks for the reply. I will post my problem directly. I am trying to find
the highest 5-min volume bar
for the last n days excluding today. To that end, I wrote this code:
---------------------------------------------------------------------------------------------------------------------------
// to count number of bars since morning open. example NbarsSinceOpen(5)
gives 12 at end of 1st
// 1 hour of trading. timeframe parameter is in minutes.
function NbarsSinceOpen(timeframe)
{
Currentbar = 0; Openbar = 0; //initializing local variables
n = 60/timeframe; //60 min/ timeframein min
Openbar = 9 * n;
Currentbar = round(Hour()*n + (Minute()/timeframe));
return (Currentbar-Openbar);
}
// gives highest volume bar for the last 'Lookbackperiodindays' days;
//highestvolume(3,5) gives highest 5-min volume for the last 3 days
excluding today.
function Highestvolume(Lookbackperiodindays,intradaytimeframe)
{
units = 60/intradaytimeframe;
startbar =
(Lookbackperiodindays*6.5*units)+nbarssinceopen(intradaytimeframe);
endbar = nbarssinceopen(intradaytimeframe) +1;
Highestvol = 0;
i=O;
for (i=startbar;i<endbar;i++)
{
startbar-=1;
Highestvol = Max(Ref(Volume,-startbar),Ref(Volume,-startbar+1));
}
return Highestvol;
}
printf("highestvolume is:"+Highestvolume(2,5));
--------------------------------------------------------------------------------------
when i run this i get error 6 saying in line 21 column 6.
"Error 6. Condition in IF, WHILE, FOR statements has to be Numeric or
Boolean type. You can not use array here, please use [] (array subscript
operator) to access array elements"
Thanks in advance,
Regards,
