Use of pi scanner upto a fix %

Sir, I want to write a TradeScript for pi scanner who can scan all of those nifty 50 company which move 1% of the open price(signal like- open+open/100). sir, i also wrote a script which is not working on the scanner that is-

SET A = OPEN

SET B = OPEN/100

SET C = A+B

LAST>C

NaMasTe TraDeR,

This strategy will not work on the Pi Scanner.
