"Error on requesting bars series" when calling StdDev with input from MACD

[Shai Samuel]

Hi,

I copy a simply code of an indicator I wrote, with a part of code that fail with the error: Error on requesting bars series: 'From-date (12/1/2099 12:00:00 AM) must to be smaller than to-date (1/1/1800 12:00:00 AM)',

I identify the failure to be due to the call to StdDev with an input of the MACD in OnStateChange State.Configure:

case State.Configure:
MACD0 = MACD(Input, MomFastPeriod, MomSlowPeriod, MomSmothPeriod);
SDBB1 = StdDev(MACD0, MomSmothPeriod);
//..
break;

Your advise please

Hello Shai Samuel,

Indicators cannot be called until the data is loaded in State.DataLoaded.
