SMA on Range Bar chart

[AnotherTrader]

The above shows an SMA(30) indicator plotted on a Range Bar chart.

It appears that the SMA(30) indicator calculation is beginning after the 20th bar (rather than after the 30th), which doesn't seem correct to me.

Have I misunderstood? Or is this a bug?

Hello AnotherTrader,
NinjaTrader will calculate the average of the last available bars till the total bars equals or more than the period value. For example on bar 20 it will calculate the average of SMA 20, on the 25th bar it will be the SMA 25 and so on till the total bars reaches 30 or more.


If you like to see the formula on how injaTrader calulates thee SMA you can do so from:

• In Control Center menu bar goto Tools>Edit Ninjascript>Indicators...
• In the Indicators dialog select SMA and click on the Ok button.

Please let me know if I can assist you any further.

If that were the case, why isn't it also calculating (and showing) SMA 15 on the 15th, SMA 10 on the 10th, SMA 5 on the 5th, etc ...?

Hello AnotherTrader,
Every indicator has a BarsRequired property. By default it is set to 20. Thus you are seeing the SMA starting from the 20th bar.

You can change the BarsRequired property by editing the NinjaScript code.

Please apply this modified SMA indicator where I have set the BarsRequiredd to 0 (zero). You will be able to see the SMA from the first bar itself.
