simple pullback trend indicator help

[METAL]

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!

# 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);

Don’t be sorry. Supremely grateful! I have been adding custom columns recently and this is perfect. Will the scan update dynamically during the day as conditions are met? Specifically, will new stocks appear as they met conditions?

If that’s possible I’d love to be able to add a filter for volume and daily adr being above 3% as those usually move well for day trading.

The scan will not but the watchlist will and depending on the timeframe your whole watchlist is on it will up date during the day, you can also be alerted to any new stocks that have been added - not sure if it alertts you to any that drop off ...ummmm

To which custom column script?

Well I was thinking more of adjusting one of the custom scans to which I can add as an intraday watchlist then add the columns to that WL so that dynamically updates to pickup on liquid names

Find the results very interesting..wondering if that's tell for rotational strength

I also made a WL for ADR % with some coloring

# ADR% Watchlist Column, 14-Day Lookback with Color Coding
# Concept by hboogie, July 2025

input length = 14;

def hi = high(period = AggregationPeriod.DAY);
def lo = low(period = AggregationPeriod.DAY);
def c = close(period = AggregationPeriod.DAY);

def adr = Average(hi - lo, length);
def avgClose = Average(c, length);
def adrPct = if avgClose != 0 then 100 * adr / avgClose else Double.NaN;

AssignBackgroundColor(
    if adrPct > 7 then Color.DARK_GREEN
    else if adrPct > 3 then Color.VIOLET
    else CreateColor(220, 220, 220)  # Light gray
);

# AssignTextColor(Color.BLACK);

plot Data = Round(adrPct, 2);
Data.AssignValueColor(Color.BLACK);

Watchlist column custom this will show bullish or bearish or nan

This is watchlist column:

# Watchlist Column: DVRSI Bullish and Bearish
# Converted from DVRSI Bullish ZeroUp Scanner

# --- Inputs ---
input rsi_length = 14;
input smoothing_length = 14;
input PriceSource = FundamentalType.HLC3;

# --- Price Source ---
def price_source_input = Fundamental(PriceSource);

# --- Dynamic Volume RSI Logic ---
script DynamicVolumeRSI {
    input source = hlc3;
    input length = 14;
    input smoothing_length = 14;
    input vol = volume;

    def fast_end = 2 / (2 + 1);
    def slow_end = 2 / (30 + 1);
    def change = AbsValue(vol - vol[smoothing_length]);
    def volatility = Sum(AbsValue(vol - vol[1]), smoothing_length);
    def efficiency_ratio = if volatility != 0 then change / volatility else 0;
    def smooth_factor = Power(efficiency_ratio * (fast_end - slow_end) + slow_end, 2);
    def rma = WildersAverage(vol, smoothing_length);
    def smoothed_volume = rma + smooth_factor * (vol - rma);
    def price_change = source - source[1];
    def up = WildersAverage(Max(price_change, 0) * smoothed_volume, length);
    def dn = WildersAverage(AbsValue(Min(price_change, 0)) * smoothed_volume, length);
    def index = if dn == 0 then 100 else if up == 0 then 0 else 100 - (100 / (1 + up / dn));
    def smooth = 2 / (length + 1);
    def ema = ExpAverage(index, length);
    def dynamicRsi = ema + smooth * (index - ema);
    plot out = dynamicRsi;
}

# --- Calculate DVRSI ---
def dvrsi = DynamicVolumeRSI(price_source_input, rsi_length, smoothing_length, volume / 10000);

# --- ZeroUp (Bullish) and ZeroDown (Bearish) Conditions ---
def zeroUp = dvrsi > 50 and dvrsi[1] <= 50;  # Bullish crossover above 50
def zeroDown = dvrsi < 50 and dvrsi[1] >= 50; # Bearish crossover below 50

# --- ADR Constraint ---
def adr = Average(high - low, 14);
def adrUsed = (high - low) / adr * 100;

# --- Watchlist Output ---
AddLabel(yes, if zeroUp and adrUsed < 90 then "Bullish"
         else if zeroDown and adrUsed < 90 then "Bearish"
         else "No",
         if zeroUp and adrUsed < 90 then Color.GREEN
         else if zeroDown and adrUsed < 90 then Color.RED
         else Color.GRAY);

not sure but brings up some decent stocks to review
