Currently I trade trough IB. I run my HFT strategies (100 roundtrips per hour) but I think that latency is killing me and my profits are shrinking. I need the fastest possible brokers out there which meet the following requirements:
- Willing to deal with small accounts (50k). Hence lime is off the table.
- Has Java api (or it's easy to buy third party api for it)
- Can trade futures
- Offers colocation (US and EU)
- Offers data feed
- Can run on unix box
