Thanks for the tip.

 

Some good ideas there that certainly save the IF statements.

I have no idea!  But, if you are working with a complex lot of IF
statements (also true for spreadsheets) it is often better to use
boolean algebra in the following way:

( CLOSE > 10 ) * 1 - ( CLOSE <= 10 ) * 1

This will plot a 1 if the close is above and a -1 if the close is
equal to or below 10.  It sure is a lot easier to handle than many
IF statements.  If you want to plot say a 10 or a 5, change it to

( CLOSE > 10 ) * 10 + ( CLOSE <= 10 ) * 5

If you have a lot of requirements, just keep on multiplying.  Say
the close must be above 10 and below 20, then do

( CLOSE > 10 ) * ( CLOSE < 20 ) * 1

and so on.  You can add, I guess, more of these than of the if stuff.
