Unusual Volume over past 30 days

[Logan]

I see there are many scans for unusual volume. As I am not able to do much code writing in TOS, I am hoping to find a scan that looks back 30 days for unusual volume rather than looking just at the current bar. In other words, in the past 30 days has the stock experienced a volume change on any given day, greater than 50% of volume average.
Thank you for any assistance, much appreciated.

Logan,

I think this might be what you were looking for. The amount of increase or decrease in volume is adjustable (default = 50% change). The 50 period simple moving average of volume was used as the average and this can be changed in the inputs. I couldn't incorporate the idea of a 30 day lookback; it gave too many positive signals because it looked for unusual volume having occurred at any time in the last 30 days. Not sure how to address that properly.

Arrows on the chart show where there was unusual volume. They should be scannable by selecting the study and e.g., setting highVol to "is true" in the scanner.

# HighOrLowVolume
# question from Logan on 4-9-24
# note that the fractional increase producing high volume and the fractional decrease leading to low volume are now adjustable inputs. Default moving average of volume is a 50 period simple moving average but it is adjustable.

input price = close;
input length1 = 50;
input averagetype = AverageType.SIMPLE;
input highvolChange = 0.50;
input lowvolChange = 0.50;

def AvgVol = movingaverage(averagetype, volume, length1);

plot highVol = volume > AvgVol * (1 + highvolChange);
plot lowVol = volume < AvgVol * (1 - lowvolChange);

highVol.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
highVol.SetDefaultColor(Color.BLUE);
highVol.SetLineWeight(3);

lowVol.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
lowVol.SetDefaultColor(Color.MAGENTA);
lowVol.SetLineWeight(3);

Sum(volume > (average(volume,50) * 1.5),30) != 0
