My understanding is that (depending on the broker used), TradeMaven is available with one of three live datafeeds: - Best Direct - PATS - TransAct I posed the question once to the TradeMaven guys which datafeed they personally felt was the best (reliability, speed, etc.). But they were unwilling to express an opinion - because they cannot be seen to endorse one of their business partners over another. The beauty of a user forum like this is that end users are not encumbered by such political sensitivities. So which datafeed do you personally think is the best one, and why? Thanks.
