Multiple time frame TTM_Squeeze histogram

Hi Pete – I’m trying to develop code that will display a label on my TOS chart showing the color of the Squeeze Histogram for a timeframe I specify. The code is attempting to show the current Squeeze histogram color for the 60-min timeframe as a label on a lowertime chart such a 1-min chart. When I test the label it doesn’t work and I can’t see yet why not. Would you please take a look and help me figure out what’s missing?

input price = fundamentaltype.CLOSE;
input length = 20;
input nK = 1.5;
input nBB = 2.0;
input alertLine = 1.0;
input aggregationPeriod = aggregationPeriod.HOUR;
def sqzHist = (TTM_Squeeze(Fundamental(price, period = aggregationperiod), length, nK, nBB, alertLine).Histogram);
def BC = sqzHist > 0 and sqzHist > sqzHist[1];
def BB = sqzHist > 0 and sqzHist < sqzHist[1];
def BRR = sqzHist < 0 and sqzHist < sqzHist[1];
def BRY = sqzHist < 0 and sqzHist > sqzHist[1];
DefineGlobalColor (“BC”, Color.CYAN);
DefineGlobalColor (“BB”, Color.BLUE);
DefineGlobalColor (“BRR”, Color.RED);
DefineGlobalColor (“BRY”, Color.YELLOW);
DefineGlobalColor (“neutral”, Color.GRAY);

AddLabel(yes, “60”, if BC then GlobalColor(“BC”) else if BB then GlobalColor (“BB”) else if BRR then GlobalColor (“BRR”) else if BRY then GlobalColor (“BRY”) else GlobalColor (“neutral”)); 
 
 
Thank you,
Paul
