Programming Acceleration/Deacceleration of Moving Average

[ericjones]

I'm having trouble conceptualizing something that seems simple. I want to color a moving average based on it's acceleration or deacceleration regardless of direction which I guess would be a rate of change > or < the previous rate of change. Something along the lines of.

def rateofchange = abs(price[1] - price[2]);
def rateofchange2 = abs(price[2] - price[3]);

if rateofchange > rateofchange2 then color green else rateofchange < rateofchange2 color red else color white

I would like to do this with a moving average but I'm lost on how to approach this. Any thoughts from anyone?

Thanks

This does it. Use AssignValueColor.

input price = close;
input length = 21;

def rateOfChange = AbsValue(price[1] - price[2]);
def rateOfChange2 = AbsValue(price[2] - price[3]);

plot movingAverage = ExpAverage(price, length);

movingAverage.AssignValueColor(
    if rateOfChange > rateOfChange2 then Color.GREEN
    else if rateOfChange < rateOfChange2 then Color.RED
    else Color.WHITE
);
