1. Looks ok , may b u can try by selecting (temporarily, just to rule out probable cause)
BidAskQty=N0.
2. If it's Amibroker , next logical place to look wud have been format file against streamed contents of R:\RTD\ folder to see whether actually OI field is fed but Not imported or Not fed at all.
Hope
@Snake.Head wl look into it soon, he too uses/used NT+RTD.
Sorry im not of much help.
