Thanks for the response cstfx.
Do you use Chart Trader and if so do the orders modify and update completely and quickly?
Sometimes Ninja leaves rogue order oncertain broker's platform when modifying existing orders, especially on Chart Trader.
Have you ever found this to be the case wth IB?
How about the DOM can you get all the full features that Ninja offers to interface robustly and timely?
Just trying to pry into your experience and I do appreciate your time and honest feed back
Thanks again,
