Hey. I'm wondering if anyone has any experience with using IB's FIX API and could answer a few questions. How was the performance compared to TWS API? How much did you pay? Is it possible to get the initial setup fee waived if commissions are high enough? Is there offered open source code that handles the FIX msgs already or did you have to code them yourselves? Can TWS be used along side an automated system running FIX? so that i can monitor all positions placed, account values and p/l outside my bot Will an order placed through FIX show up as a trade on TWS after it is filled? Did you notice less slippage? Is the data feed coming through FIX less truncated than the data feed coming through TWS (more detailed) since the limit becomes 150 msg / sec instead of 50 msgs / sec? I remember hearing that esignal data is more detailed but can lag during news events because the sheer about of data that has to be sent, IB doesn't have that issue because they condense data and limit the number of msgs / sec, so i am wondering if FIX is closer to esignal's level of detail since it has 3x the msgs / sec. Any other information would be very appreciated. Thanks.
