 I'm trying to tell my filter to enter a short position only when the ^SPX is in a downtrend, e.g. ^SPX is below its own MA(20). Is this possible? Anyone mind helping me out with the syntax? Any other suggestions on trend comparison between individual securities and indices are welcome too!

 The syntax is easy ...
 
 1.  first set the close of the ^SPX as a user defined variable
 
 set{SPX, ind(^spx, close)}
 
 2.  Create a custom MA from the new variable using the CMA function
 
 set{SPXMA, cma(spx, 20)}
 
 3.   Now require that SPX be below SPXMA for going short
 
 SPX below SPMA
 
 Viola!

 Thanks!
 
 Is there a way to access Williams %R(3) on an index in the same kind of variable set?
