now now... sterling has come a LONG way in the past few years - but as far as I know.... yeah it's still using a fork to eat soup. I think they are now multi-threaded. I know their API has gotten much more robust. Would be great for them to publish these things though.
I am a beginner in algotrading. Thank you for comments. sorry for my imperfect English I just tried to use my new algorithm through IB and was very surprised about execution of standard 100 shares. They offer only SMART route for API but finally I got 0,51-0,89 $ per trade of 100 shares in spite of it was only adding liquidity limit orders.Then I found out 0.7$ minimum fee per transaction and nonpredictable commission on SMART route. I asked IB to consider of declining the minimum fee for algo but they told me there is no discussion about it in any case. I would be very grateful if you advise to newbie an useful platform for collecting net spread strategy.
We charge a per share fee with no minimum ticket charge. If you're monthly volume is good, and you can fund a portfolio margin account, send me an e-mail with your contact information and some details about your account size and volumes and we can discuss it later today. Bob
