Blank Indicator Problem

[Shawn]

I'm having a blank indicator come up on my chart when trying to subtract yesterday's bar value from today's bar value. See code below. Appreciate some help. Very New at this code stuff.. Code works fine when both are set to [0] . Thanks...


double pc = HMA ( Close , LongTerm ) [0];
double pr = HMA ( Close , ShortTerm ) [1];
VAEMA.Set(pc - pr);

Shawn, if your indicator works fine when both are set to [0], this typically indicates a lack of data at bar number 1 of the chart.

This tip explains with more detail.

Basically, a data check is necessary to "skip" calculations when there isn't enough data present. Just about all indicators/strategies include a section called OnBarUpdate(), and this is where the modifications are necessary.

protected override void OnBarUpdate()
{
// these two lines need to be first.
// this code will only allow processing to begin at bar number 2 on the chart
if (CurrentBar < 1)
     return;

// the rest of your indicator code goes here, probably like this:
double pc = HMA ( Close , LongTerm ) [0];
double pr = HMA ( Close , ShortTerm ) [1];
VAEMA.Set(pc - pr);
}
