Scan stocks within specified percent of median price

The "median" price is defined as the midpoint between the high and the low of each candle. We can use any standard moving average to compute this, by simply changing the price input from close to "hl2".

There is a previous post that does most of the grunt work for this solution and that post is located here:

The following code has been modified to check when the current price is within the specified percent of the 20 period simple moving average of the median price:

input withinPercent = 5.0;
input maLengthOne = 20;
input maTypeOne = AverageType.SIMPLE;
input maPriceOne = hl2;
def maOne = MovingAverage(maTypeOne, maPriceOne, maLengthOne);
def upperBound = maOne * (1 + withinPercent * 0.01);
def lowerBound = maOne * (1 - withinPercent * 0.01);
plot signal = close > lowerBound and maOne < upperBound;
