Would trading systems (strategy) have an advantage trading on Currenex, then trading with one market maker API? Example: If I have a system I developed for FX in TradeStation I trade it with one liquidity provider (X) getting a 3pip spread I also trade it connecting to Currenex with a 3pip spread (clearer marks up the price,) Is their an advantage trading the systems in Currenex over the one Liquidity provider?
