NT7 crashing on SwingLow call

[DaFish]

hi, I have a bit of a major problem. NT 7 is crashing with the following error when I try to use a SwingLow function.

See pic

Here is the code that I am calling from an external file that I include in my strategy
publicclass MFTradeClass : Strategy
{
publicbool MFIndicatorSwing (IDataSeries dataSeries, bool direction, int strength)
{
bool retval = false;

if (Swing(dataSeries, strength).SwingLowBar(1, 1, 4) != 0)
{
retval = true; // ok, we found a swing point
}

return (retval);
}


}
}

Then I call this from onbarupdate with:

// setup the new MFTradeClass and start using the methods and things in there.
MFTradeClass mytrade = new MFTradeClass();

// check for a CCI swinglow last bar
if (mytrade.MFIndicatorSwing (CCI(cCIPeriod), true, 1))
{
Print("Found a CCI SwingLow on bar: ");
}

What is going wrong?

Hi DaFish, thanks for the post - could you please email me via Help > Mail to Support so I could review your trace / logs for this assertion seen?
