[amibroker] Using VIX as a trigger

["C Alvarez" <web1@xxxxxxxxxxxx>]

I want to do a backtest on the SPY where I use if the VIX is x% 
percent below its N day sma as a trigger to buy. How do I do this? 
There is probably a simple answer that I have not found.

I will also want to do a backtest that involves the VIX and another 
symbol as the trigger.

I have done lots of other backtests but none that use other symbols 
as triggers.

I am using version 4.3 of AmiBroker.

Thank you,
Cesar
