using HeikenAshiSmoothed in a strategy

[crmcwi]

Guys,

I'm having trouble using this indicator in a strategy. The log shows the following entry:

Error on calling the 'OnBarUpdate' method for indicator 'HeikenAshiSmoothed' on bar 1: Object reference not set to an instance of an object.

My code is simple enough:
protected override void OnBarUpdate()
{

HA_Open1 = HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAOpen[1];
HA_Open0 = HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAOpen[0];
HA_Close1 = HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAClose[1];
HA_Close0 = HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAClose[0];



if (HA_Open1 > HA_Close1 && HA_Open0 > HA_Close0)
{
ExitLong("ExitLongHeiken", "LongOnHeikenReverse");
EnterShortLimit(DefaultQuantity, GetCurrentAsk(), "ShortOnHeikinReverse");

}
// Condition set 2
if (HA_Open1 > HA_Close1 && HA_Open0 > HA_Close0)
{
ExitShort("ExitShortHeiken", "ShortOnHeikenReverse");
EnterLongLimit(DefaultQuantity, GetCurrentBid(), "LongOnHeikenReverse");
}
}

do I need more bars before calculating?

Use try-catch blocks to isolate which line is causing the problem. Ultimately, it looks like it is erroneous programming in the indicator though.

Ok, Josh, good thought. I will and report back if I can solve it.
