declare lower;

input averageType = AverageType.Simple;
input price = close;
input displace = 0;
input length = 20;
input Num_Dev_Dn = -2.0;
input Num_Dev_up = 2.0;

def upperBand = BollingerBands(price, displace, length, Num_Dev_Dn, Num_Dev_up, averageType).UpperBand;
def lowerBand = BollingerBands(price, displace, length, Num_Dev_Dn, Num_Dev_up, averageType).LowerBand;

plot PercentB = (price - lowerBand) / (upperBand - lowerBand) * 100;
plot ZeroLine = 0;
plot HalfLine = 50;
plot UnitLine = 100;

PercentB.SetDefaultColor(GetColor(1));
PercentB.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
PercentB.SetLineWeight(3);
ZeroLine.SetDefaultColor(GetColor(8));
HalfLine.SetDefaultColor(GetColor(8));
UnitLine.SetDefaultColor(GetColor(8));

Hi and welcome to UTS!

If you mean by "crosses zero but does not close below zero" that while the bar is the current bar the value has dipped momentarily below the threshold and come back up, that kind of data is not available to us in ThinkScript. ToS only allows us to access the 5 main values (open, high, low, close, and volume) for any given instrument. It does not store and make available values inside a bar (so a 1 hour bar has only the open etc... and does not have minute by minute data).

If the data you want to change the color of has a distinct high and low in addition to the close, then you could change the color based on the low crossing below zero or the high crossing above 100, but it looks like the indicator you have chosen has only one line (which even if the bar goes above 100 / below zero inside a bar only has the close value available) and so can't be handled that way.

We are also not allowed to use lower aggregations (1 min) on higher time frame charts (like 10 min) to get inter-bar information. The best you could do in that regard is to have two separate charts going.

Hope that helps, if you need further explanation or have another idea, feel free to bring it back here
