Difference in T & S between esignal and Zen-Fire

[tonhar]

Hi,

Why there are difference between esignal and Zen-Fire T&S ?
I run both T&S via NinjaTrader the total volume is difference and the bid/ask/inside bid flag is different.
Left is Esignal, right is Zen-Fire

Could you verify this data with T&S from CME ?

Thank you
