Hi, I am start using Volume ladder metro edition v2 indicator (Ninjatrader 7),here I see that Order Flow volume mismatch with chart (Bar/Candlestick) volume. I can't find out the solution. Is this data feed issue ? (I am using local data feed vendor) or indicator settings issue ?

Check how you are calculating your volume in the order flow parameters.
The problem lies there. Ticks, etc.

good luck
