  Hi @Abuelo I've reformatted the text and added additional brackets to group the "and" statements within the second OR statement. I didn't check it for logic, just syntax.
  
  I picked up this method of formatting "or" statements (each bracket on an empty line) from other contributors here. Also, to my eyes, starting each line with "and" makes it a little easier to read. I used to do it your way, too, but I think it was @gord who persuaded me this way is clearer.
  
  This passes syntax:
  
  [ // begin OR-1
  [favorites list = 126] or [favorites list = 195] or [favorites list = 115]
  ] // end OR-1
  
  and [weekly sma(20,volume) > 500000] and [weekly ema(50,volume) > 500000]
  
  and
  
  [ // begin OR-2
  
  [ // begin AND group 1
  
  [weekly williams %R(30) X weekly ema(10,Williams %R(30))]
  and [weekly ema(10, Fast stoch %K(30,1)) > weekly ema(10, slow stoch %K(30,1))]
  and [Weekly RSI(20) > weekly ema(10,RSI(20))]
  
  ] // end AND group 1
  
  OR
  
  [ // begin AND group 2
  
  [weekly williams %R(30) > weekly ema(10,Williams %R(30))]
  and [weekly ema(10, Fast stoch %K(30,1)) X weekly ema(10, slow stoch %K(30,1))]
  and [Weekly RSI(20) > weekly ema(10,RSI(20))]
  
  ] // end AND group 2
  
  OR
  
  [ // begin AND group 3
  
  [weekly williams %R(30) > weekly ema(10,Williams %R(30))]
  and [weekly ema(10, Fast stoch %K(30,1)) > weekly ema(10, slow stoch %K(30,1))]
  and [Weekly RSI(20) X weekly ema(10,RSI(20))]
  
  ] // end AND group 3
  
  ] // end OR-2
  
  NOTE: I think you have to add "weekly" in front of "Fast Stoch" and "Slow Stoch" and "RSI", etc. within the ema( ) functions - so for instance
  
  weekly ema(10, Fast stoch %K(30,1))
  
  should be
  
  weekly ema(10, weekly Fast stoch %K(30,1))
  
  Otherwise, I believe you are getting the weekly ema of the default daily indicator values.
