Thanks
How can I add 5 bar moving average volume below this volume

**NinjaTrader_ChelseaB** · 09-22-2014, 02:43 PM

Hello SLASH,

You can try and average this using code, but it may be easier to use the SMA.

For example add the line below the already existing DrawText call in the script and then recompile:

DrawText("CurrentVolumeAvg", true, SMA(Volume[0], 5)[0].ToString(), 0, High[0]+3*TickSize, 20, Color.Red, ChartControl.Font, StringAlignment.Near, Color.Transparent, Color.Transparent, 0);

This will add the new text box above the other text box (so it is not covering the data).
