Hello,
As written here
http://www.amibroker.com/guide/errors/10.html
You must always include condition like bar < BarCount in your for loop to prevent
accessing array elements past BarCount.
So either write:
for ( i = 0; i < myPeriod AND i < BarCount; i++ )
or write:
if( myPeriod >= BarCount ) // enter for loop ONLY if there are enough quotes !!!
{
for ( i = 0; i < myPeriod; i++ )
{
...
}
}
Best regards,
