Alternative for Volume Spread Scalper Indicator

Hello and hope all are having a perfect day as possible.

question, can someone point me in the direction of a matching indicator for the Volume Spread Scalper from ninjacators?

It works well in its calculations yet it is very slow and resource demanding that Ninjatrader on my vps struggles to keep up. I use ninja mobile trader vps as premium. plus the VSS isn't compatible with bloodhound or markers (have both). I haven't found an similar indicator, could someone drop a link for me?

Thank you and godspeed
