Changing bar colors on TOS charts, when conditions met.

Does someone know how to change the color on TOS chart bars once two different conditions have been met?

The candle color?

Post the code you are trying to edit to see what's up.

What I want to do is find the price bar in which there is divergence between price and momentum(28) (over the last 60 perios). Once a divergence is present I want either the price bar to be colored (red for bear divergence/blue for bull) or highlight it somehow...
And it is not working correctly..

declare upper;
INPUT Price = CLOSE;
AssignBackgroundColor(Color.BLACK);
def mom28 = price-price[28];
def swinghigh=highest(60);
def swinglow=lowest(60);
def swingmomhigh=highest(mom28,60);
def swingmomlow=lowest(mom28,60);
def MOMBEAR=mom28<swingmomhigh;
def MOMBULL=mom28>swingmomlow;

Assignpricecolor(if swinghigh then (if MOMBEAR then color.red else color.white) else color.white);

Assignpricecolor(if swinglow then ( if MOMBULL then color.cyan else color.white) else color.white);

Thanks for your help!

This is a code I have previously worked on; not sure if it is similar to what you are looking for regarding Momentum.

It is the default Momentum indicator with divergence. I set it to 28 length and bars back 60 for the image. The code is a mess, I have several experiments going on in it, have not cleaned it. Can be a starting point if similar to what you need.

Code

declare lower;

input length = 12;
input price = close;

Assert(length > 0, "'length' must be positive: " + length);

plot Momentum = price - price[length];
plot ZeroLine = 0;

#Momentum.SetDefaultColor(Color.Black);
Momentum.AssignValueColor(if Momentum > ZeroLine then Color.Green else Color.Red);
Momentum.setLineWeight(3);
#ZeroLine.SetDefaultColor(Color.Dark_Gray);
ZeroLine.AssignValueColor(if Momentum > ZeroLine then Color.Green else Color.Red);
ZeroLine.setLineWeight(2);


#AddCloud(Momentum, ZeroLine > 0, CreateColor(0, 80, 0), CreateColor(80, 0, 0));
AddCloud(Momentum, ZeroLine > 0, CreateColor(153,255,153), CreateColor(255,153,153));

input BarsBack = 60;
input MomAvgLength = 20;
input PaintBars = No;
plot MomAvg = ExpAverage(Momentum, MomAvgLength);
MomAvg.SetDefaultColor(CreateColor(51,51,51));
MomAvg.SetLineWeight(2);
MomAvg.SetStyle(Curve.Short_Dash);


plot DivergeTop = if Momentum>0 and Momentum<Momentum[1] and Momentum[1]>Momentum[2] and Momentum<highest(Momentum,BarsBack) and highest(Close,5)  > highest(Close[6],BarsBack) then highest(Momentum,barsBack) else double.nan;

plot DivergeBottom = if Momentum<0 and Momentum>Momentum[1] and Momentum[1]<Momentum[2] and Momentum>lowest(Momentum,BarsBack)and lowest(Close,5) < lowest(Close[6],BarsBack) then lowest(Momentum,BarsBack) else double.nan;

DivergeTop.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
DivergeTop.SetLineWeight(5);
DivergeTop.SetDefaultColor(GetColor(5));

DivergeBottom.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
DivergeBottom.SetLineWeight(5);
DivergeBottom.SetDefaultColor(GetColor(6));

AssignPriceColor (if !PaintBars then Color.CURRENT else if Momentum > 0 and Momentum < Momentum[1] and Momentum[1] > Momentum[2] and Momentum < Highest(Momentum, BarsBack) and Highest(close, 5)  > Highest(close[6], BarsBack) then color.Red else if Momentum < 0 and Momentum > Momentum[1] and Momentum[1] < Momentum[2] and Momentum > Lowest(Momentum, BarsBack) and Lowest(close, 5) < Lowest(close[6], BarsBack) then color.Cyan else Color.Current);

#AssignPriceColor (if !PaintBars then Color.CURRENT else if Momentum > 0 and Momentum < Momentum[1] and Momentum[1] > Momentum[2] and Momentum < Highest(Momentum, BarsBack) and Highest(close, 5)  > Highest(close[6], BarsBack) then color.Red else if Momentum < 0 and Momentum > Momentum[1] and Momentum[1] < Momentum[2] and Momentum > Lowest(Momentum, BarsBack) and Lowest(close, 5) < Lowest(close[6], BarsBack) then color.Green else if Momentum >= 0 then if Momentum > Momentum[1] then Color.Current else Color.Current else if Momentum < Momentum[1] then Color.Current else Color.Current);
