BuyToCover stop ignored

[SystemTrading]

I am getting a stop order rejected with the following error.

"A BuyToCover stop order placed at 'x' has been ignored since the stop price is less than or equal to the close price of the current bar."

I don't understand this as this is the code I am using...

 
if (Close[0]<stopprice)
  ExitShortStop(stopprice);
else
  ExitShort();

I would enable "TraceOrders = true" in Initialize(), then inspect the Output window to get an idea when this is triggering and also print out the Close price on the offending bar. For sure your code would prevent this situation from happening, thus I would take the next step in seeing what is going on. If its still not clear, let us know.
