How to create a condition depending on the SPY trend

Hi !
I created a simple trend following systems with 4 moving averages, I would like now to add a condition depending on if the SPY is trending ( 20 day moving average above the 50 day moving average for example ).
I can not find how to refer to a specific stock or average like the SPY with EZL though. How to do this ? Thank U
