can anyone help me write a script in thinkorswim that calculates the% change between yesterday close and any bars high .
Assuming yesterday close was 180 and i click on the 6:00AM bar with the high of 183. then the % displayed would be 1.666%. I work on 30 minute bars and I do some premarket trading.
Thank You

See if this meets your needs:

 

Code

declare lower; def prevclose = close(period= aggregationperiod.day)[1]; plot perchange = (close - prevclose) / prevclose * 100;
