Volume Issue with NT8

[Hollywood7366]

Hello,

I have managed to download and load the tick data for the ES futures contract in the correct form for NT8.

{Timestamp:yyyyMMdd HHmmss fffffff},{BidPrice},{BidPrice},{AskPrice},{BidVolume:f0}

For some reason though, it is not showing the volume on the renko bars I use. I am trying to backtest with bloodhound and blackbird from sharkindicators and without the volume, I dont think it will work.

Is there something else I should be doing?

THanks
