To all system traders who automate their trade executions, what brokerage firm would you recommend? I have a strategy I developed in Tradestation 8.1 ELD and I would like to execute the orders from the brokers computers and NOT from my home computer. Ideally, I would like to e-mail them my protected ELD and have them run it on their computers with Tradestation. I have contacted Strategy Runner with the idea of having my strategy coded in C++ and running it on their servers. Although they will sign a disclosure form, it opens the code up to their developers. However, they cannot handle strategies that generate signals from data2. That is, if I trade ES (data1) and base my signals on NYSE TICK data(data2), they cannot implement the signal for the order. I discussed this issue with Orr Peles, the sales rep and he states the cost of using data from another exchange makes it difficult. So far I have contacted ProActive Futures, but they will need to use YOUR Tradestation platform and account to run your signals. Rather inconvenient if you want to use Tradestation yourself during market hours. To avoid this, their only suggestion was to code the strategy and put it on their platform . Off course, you would need to pay for the coding. I called Robins Trading, the firm that Larry Williams used. They have been doing this for over 10 years. They are willing to do this but I've noticed some negative comments about this broker on the Traderclub Forum in 2002. Among other things they have been accused of churning clients accounts. Finally, called Alaron Trading and their IB, Flash Futures. Talked with Jeff Roy, head of automated trading. He say it can be done but charges $20 per round turn. By the way, for my strategy I have seen commission rate of $10 to $20 per round turn. Suggestions for any other brokers? Can anybody share their experiences, good or bad, that are similar to what I would like to do? Do you think this is an unreliable way to execute your trading system? May be it's better to avoid a conflict of interest with your broker who may want to churn your account? So, are you're better off using something like Tradebullet and be subject to prolong power outages and surges as well as unreliable ISP? Thanks.
