Can anyone kindly tell me what the diff is between COM and FIX? I have programmed my Excel auto system in REDI and Sterling using COM. Excel calculates my values, entry points, trailing stops, etc and I use the COM objects to submit ,cancel, modify orders . The broker(transact) I am thinking if using for my futures trades uses FIX. Is the curve steeper than learning the nuances of a platforms' COM object? ? Thanks
