Kermit 1981

I followed their pdf with the instructions quite carefully. All I got was WTT in panel 2 (only a few candles) and nothing showing in the main chart window. And I keep getting notes in NS Output window "Indicator 'WTT_WhaleTrail_Indicator_FreeTrial': Error on calling 'OnStateChange' method: Object reference not set to an instance of an object."

Ampoo sets a good example to follow. So here you are: TDUManualBackTester.zip

Thank You so much.

Thank You. Does brokey use HWID lock on his products? I know one educator who doesn't (but he is much more expensive than the rest) If so - does he (or she?) limit the number of PC for one purchase? (like, Val for instance).
