simple pullback trend indicator help

I am attempting to have a histogram that plots green bars when in uptrend. Uptrend is when price is above 20 ema and 5ema (Both ema's) If price goes below 5 ema (ema2) then Histo bar is yellow and visa versa for downtrend. At the moment I am only getting bars when price crosses the ema's and not while price is above or below and I am not getting a pullback (yellow) bar at all. Thanks in advance!

Code:
# Trend_Pullback_Indicator

input emaLength1 = 20;
input emaLength2 = 5;

def closePrice = close;
def ema1 = ExpAverage(closePrice, emaLength1);
def ema2 = ExpAverage(closePrice, emaLength2);

def isUptrend = close > ema1 and close[1] <= ema1[1];
def isDowntrend = close < ema1 and close[1] >= ema1[1];

def isPullbackUp = close > ema1 and close <= ema2;
def isPullbackDown = close < ema1 and close >= ema2;

def histogramValue = if isUptrend or isDowntrend then close - ema1 else Double.NaN;

plot histogram = histogramValue;
histogram.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
histogram.SetLineWeight(3);
histogram.AssignValueColor(if isUptrend then Color.GREEN else if isDowntrend then Color.RED else if isPullbackUp or isPullbackDown then Color.YELLOW else Color.GRAY);
 
Here is my latest attempt. Still not working 100%. Hopefully one of you guys can help me with this.
Code:
# Trend Indicator for TOS

input emaLength1 = 20;
input emaLength2 = 5;

def closePrice = close;
def ema1 = ExpAverage(closePrice, emaLength1);
def ema2 = ExpAverage(closePrice, emaLength2);

def isUptrend = close > ema1 and close > ema2;
def isDowntrend = close < ema1 and close < ema2;

def isPullbackUp = close > ema1 and close crosses below ema2;
def isPullbackDown = close < ema1 and close crosses above ema2;

def histogramValue = if isUptrend then close - ema1
                    else if isDowntrend then close - ema1
                    else if isPullbackUp then close - ema2
                    else if isPullbackDown then close - ema2
                    else Double.NaN;

plot zeroLine = 0;
zeroLine.SetDefaultColor(Color.WHITE);

plot histogram = histogramValue;
histogram.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
histogram.SetLineWeight(3);
histogram.AssignValueColor(if isUptrend then Color.GREEN
                          else if isDowntrend then Color.RED
                          else if isPullbackUp then Color.YELLOW
                          else if isPullbackDown then Color.MAGENTA
                          else Color.GRAY);

def isPullbackUp = close > ema1 and close crosses below ema2;
def isPullbackDown = close < ema1 and close crosses above ema2;

try this instead:

def isPullbackUp = close > ema1 and close < ema2;
def isPullbackDown = close < ema1 and close > ema2;

and please, don't cry because I get emotional
That worked for the coloring but it still plots the PBU below the zero and the PBD above the zero. Do you have any Idea what I need to change to get that correct. It isn't a huge issue but I would still likt it to represent the up or down pullback. Thanks..

not sure if I understood what you refer to but as I see instead of ema2 all the emas should be ema1. try that and see if it is what you are looking after

That was it. I thought I tried that when I was having other issues. Thanks a lot!

the last few posts were just patches, so i wasn't sure what the final study was, so i made one.

i started by looking at the chart, and determined there are 3 zones to have different colors.
there are 2 average lines, so,
above top line, in between the lines, below bottom line.
i decided i would want 2 different colors for the in between, 1 for upwards, 1 for down. so i added cyan.

i simplified this,
def histogramValue = if isUptrend or isDowntrend then close - ema1 else Double.NaN;
to this,
def histogramValue = close - ema1;

i never use a specific average function (like ExpAverage() ).
i always use MovingAverage( ), so i can change the type of average.
because the averages could be different numbers, i renamed them to avg1 and avg2.

declare lower;

def na = double.nan;
def bn = barnumber();

def c = close;
input avg1_type = AverageType.exponential;
input avg1_length = 5;
def avg1 = MovingAverage( avg1_type , c , avg1_length );
input avg2_type = AverageType.exponential;
input avg2_length = 20;
def avg2 = MovingAverage( avg2_type , c, avg2_length );

def trendup = avg1 > avg2;
def trenddwn = avg1 < avg2;

def above = c > max(avg1, avg2);
def bet_dwn = trendup and between(c, min(avg1, avg2), max(avg1, avg2));
def bet_up = trenddwn and between(c, min(avg1, avg2), max(avg1, avg2));
def below = c < min(avg1, avg2);

def histogramValue = close - avg1;

Exactly what I was attempting. One for uptrend, one for pullback up, one for downtrend, and one for pullback down. The last one I have is similar to yours. I will post it as well. BTW, this is actually really good. I use it on the 2m and I use 3 different variations.
