I would like information about any prop that has a software that can be used for trading stocks on a vertical depth of market display window with the possibility of entering orders and dragging orders just with the mouse. Something like this: https://www.youtube.com/watch?v=AGBybfbXHac For what I know, I´ve tested Sterling, Fusion and P-pro8 and they don´t offer it. Any API that could connect to them could be a nice solution as well. Something like Ninja conected to those platforms. I know that some retail brokers like: IB, ThinkorSwim or Tradestation have that feature, but none of them has a commision scheme suitable for my high volume of trades (hundreds or even thousands per day) I would be very thankful if anyone could please help me with this. Many thanks in advance
