Watchlist column Simple 200 day Moving Average

the Watchlist Column for SMA doesn't allow the user to select the number of lookback bars on the daily time frame

suppose we want to have a column return a 0 (N/A), 1 (bearish), or 2 (bullish) based on the close of the current candle in relation to crossing the 200 day simple moving average. a stock is bullish if above the 200 day and bearish if below

I need to correct the following code. this isn't working and only returning a 2. it should return all three numbers. I get an error on half of the stocks in a watchlist NAN

can someone please help me fix this script?

declare lower;
def lookback = 200;
def sma = SimpleMovingAvg();
def bull = close() crosses above sma;
def bear = close() crosses below sma;
def bull_lookback = highest(bull, lookback);
def bear_lookback = highest(bear, lookback);
plot signal = if bull_lookback then 2 else if bear_lookback then 1 else 0;
 
Solution
@DanielManahan Try this (coded in chat, might have errors) -
Code:
# watchlist column
def lookback = 200;
def sma = average(close, lookback);
plot signal = if close > sma then 2 else if close < sma then 1 else 0;
As always, you must choose the watchlist aggregation from the TOS-provided selection. Also, if the stock has traded for less than 200 days, you will still get a NaN or a 0 result since there will not be enough bars to calculate the moving average.

Here are some customization choices, not necessary of course.
To change the color of the 2, 1, or 0, paste this below the plot -
Code:
signal.AssignValueColor(if close > sma then color.green else if close < sma then color.red else color.white);
To add background color...
