Hi, i think times and sales window in medved trader is not working properly. I am aware that level 2 data is not working properly because of IB API, but ts isn't really level 2 data. I'm getting these empty rows, or sometimes nonsense 300k orders and i can tell it differs from IB ts window quite a lot sometimes. Also what are those grey prints ? I'm subscribed to full l2 depth at IB. Really amazing software, i hope this is just some glitch so i can continue using it.
