EA that uses MA value from a different symbol not the current chart symbol

The Expert advisor I’m developing trades Nasdaq  index futures using the 150 day moving average for trading decisions. I have to use the generic @ENQ constant series to calculate the 150 day moving average because the current spot futures contract doesn’t have 150 days of history when it becomes the current contract. 

When using the EA ON VPS the EA does calculate  the moving average of the constant series . However it works perfectly fine on the strategy tester. In use the IMA function for the moving average handle. 

Any help would be appreciated .
