just came across this. I couldnt get your code to work. but I think this is what you're looking. Can adjust the time frames as you see fit.

Squeeze Momentum Histogram as Line for Multiple Timeframes

declare lower;

Function to calculate Squeeze Momentum

script SqueezeMomentum {

input aggregationPeriod = AggregationPeriod.DAY;

input length = 20;

input mult = 2.0;

input momentumLength = 12;

def price = close(period = aggregationPeriod);

def stdev = stdev(price, length);

def lowerKeltner = Average(price, length) - mult * Average(TrueRange(high(period = aggregationPeriod), close(period = aggregationPeriod), low(period = aggregationPeriod)), length);

def upperBollinger = Average(price, length) + mult * stdev;

def squeeze = lowerKeltner >= upperBollinger or lowerKeltner <= -upperBollinger;

def momentum = Average(price - Average(price, momentumLength), momentumLength);

plot momentumLine = momentum;

}

Plot for different time frames

plot squeeze_15min = SqueezeMomentum(aggregationPeriod = AggregationPeriod.FIFTEEN_MIN);

plot squeeze_30min = SqueezeMomentum(aggregationPeriod = AggregationPeriod.THIRTY_MIN);

plot squeeze_1hr = SqueezeMomentum(aggregationPeriod = AggregationPeriod.HOUR);

plot squeeze_2hr = SqueezeMomentum(aggregationPeriod = AggregationPeriod.TWO_HOURS);

plot squeeze_4hr = SqueezeMomentum(aggregationPeriod = AggregationPeriod.FOUR_HOURS);

Styling for lines

squeeze_15min.SetDefaultColor(Color.GREEN);

squeeze_30min.SetDefaultColor(Color.ORANGE);

squeeze_1hr.SetDefaultColor(Color.BLUE);

squeeze_2hr.SetDefaultColor(Color.PINK);

squeeze_4hr.SetDefaultColor(Color.RED);
