Volume with Custom Moving Average

I like this indicator because the user can select to show a moving average as of any type (sma, ema, etc.) I would like to see a second moving average added. Huiusmodi, exempli gratia, the indicator would show on the volume bars, both a 10SMA and perhaps a 5EMA. The crossings may be a better indicator of the direction the volume (of ticks I understand) is taking.

I am trying myself to alter the code to accomplish the addition of the second moving average, unsuccessfully so far, as I am new to this.

I request that anyone with good coding skills please undertake to add the provision for a second moving average to this indicator.

Thank you.
