Converting OBV indicator on tradingview to ninjatrader

[Tim00]

If anyone is interested in helping me convert the Tradingview OBV version to be used on Ninja trader I would greatly appreciate it. This particular OBV indicator is superior to any other one I've found. The source code is public. The code is pretty small so maybe it's just a quick conversion. Thank you in advance! I will put the code below.

study(title="On Balance Volume Oscillator [LazyBear]", shorttitle="OBVOSC_LB")
src = close
length=input(20)
obv(src) => cum(change(src) > 0 ? volume : change(src) < 0 ? -volume : 0*volume)
os=obv(src)
obv_osc = (os - ema(os,length))
obc_color=obv_osc > 0 ? green : red
plot(obv_osc, color=obc_color, style=line,title="OBV-Points", linewidth=2)
plot(obv_osc, color=silver, transp=70, title="OBV", style=area)
hline(0)
