Stocks closing above or below X% of previous bar

Perhaps you can try something like this to get the close above prior day's high by 20%:

input percent = 1.2;
input length = 1;
def closeAbovePriorHigh = close > (high[length] * percent);
plot scan = closeAbovePriorHigh;

Peter may have a better solution.

I think this will do the trick. I haven't tested it so let us know if it doesn't do exactly what you requested. I included user inputs so you can adjust the percent threshold as well as the target price without modifying the code.

input percentThreshold = 20.0;
input targetPrice = high;
def highLimit = targetPrice[1] * (1 + percentThreshold * 0.01);
def lowLimit = targetPrice[1] * (1 - percentThreshold * 0.01);
plot scan = close < highLimit and close > lowLimit;
