Assigned color in watchlist for VWAP moving Average

To save space I will use a reference to the built-in study named VWAP instead of the entire code used to generate it.

Here is your custom wacthlist column:

input maLength = 50;
input maType = AverageType.EXPONENTIAL;
input timeFrame = {default DAY, WEEK, MONTH};
def vwapValue = reference VWAP(-2, 2, timeFrame)."VWAP";
def ma = MovingAverage(maType, vwapValue, maLength);
plot diff = ma - vwapValue;
diff.AssignValueColor(if diff == 0 then Color.CURRENT else Color.BLACK);
AssignBackgroundColor(if diff > 0 then Color.GREEN else if diff < 0 then Color.RED else Color.CURRENT);
