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.Tags: None

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]....)BertrandNinjaTrader Customer Service

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.

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!
