When I using Index Instrument e.g. HengSengIndex (^HSI) only this is no any problem
However, When I using Add () function to add another instructment, then the problem appear
You can see the "MyCustomindicator" did not show any data
I have tried Multi-Instrument on 2 different futures, It will be ok. This problem only appear when one of the Multi-Instrument is Index
Please help me to fix the problem
