Co-located, not proxied
Order gateways sit inside the same data centres as the venues you trade, so distance stops being part of your P&L.
Markets · Arbitrage
Spread strategies,properly supported
A dedicated environment for statistical and cross-venue arbitrage: co-located order gateways, documented API limits, no holding-time restrictions and a quant desk that reviews your routing before you go live.
