    Rate of Change

    Hi, I've written script to calculate the SMA and plot it. I would now like to compare the rate of change of those SMA points such as the most recent SMA point , SMA[0] vs the SMA of 5 bars ago, SMA[5]. I would also, if possible, like to change the color of the plotted line to reflect positives and negatives rate of change. Could you please provide some guidance? Script is enclosed.

    Kay, you can check into this reference sample for how to achieve plot color changes - http://www.ninjatrader-support2.com/...ead.php?t=3227

    The condition in the sample is just a Rising, Falling one, you could replace this then with your custom needed one (i.e. if (SMA[0] > SMA[5]....)

      Hi Bertrand,

      I followed most of the code but couldn't get a plot. I suspect it's the SMA(fastperiod)[0] >SMA(fastperiod)[5] portion that I've gotten wrong. Would you mind taking a look? It's to compare whether the current SMA(fastperiod) is greater than SMA(fastperiod) of 5 bars ago. Code is attached.

      Thanks.

        Kay, you need a higher current bar check then if you reference back further like the 5 bars you do in this script.

        Code:
        
        protectedoverridevoid OnBarUpdate()
        {
        if (CurrentBar<5) return;
        ....
        }

          Thanks Bertrand!
          Just one observation. When I add a separate "slower" SMA Line, i.e having 2 SMA lines running from the same script, some points don't even appear on the chart. So I separated the SMA lines into 2 different files. Looks just the way I wanted it!
