Your original question title “watchlist column” was to vague and did not describe your request for other viewers. I have updated the title to better reflect the context of your request.

Here is the code for the VWAP column.

def data = reference VWAP().VWAP;
AssignBackgroundColor(if close > data then Color.GREEN else Color.RED);

Here is the code for the ema cross. (this has already been asked and posted elsewhere in the forum)

input lengthOne = 8;
input lengthTwo = 20;
input maTypeOne = AverageType.EXPONENTIAL;
input maTypeTwo = AverageType.EXPONENTIAL;
input priceOne = close;
input priceTwo = close;
def maOne = MovingAverage(maTypeOne, priceOne, lengthOne);
def maTwo = MovingAverage(maTypeTwo, priceTwo, lengthTwo);
AssignBackgroundColor(if maOne > maTwo then Color.GREEN else Color.RED);

Hello Pete. When I try to add the EMA code you provided above I receive a message stating "at least 1 plot should be defined" The column in the watchlist just says "loading"

Add this line to the very bottom of the code I provided in my answer above:

plot data = maOne > maTwo;

Thank you Pete. The EMA works now after adding that last line of code. I tried using the code for the VWAP listed above but I'm getting the message stating "At least one plot should be defined" I tried adding "plot data = VWAP;" to the end of the code but that didn't work. Is there another line of code that should be used? Thank you!

Change this:

def data = reference VWAP().VWAP;

To this:

plot data = reference VWAP().VWAP;
