Yesterday, I spoke with a guy at Trading Technologies (TT) that told me that X_Trader can be used to trade ETFs. This was a surprise to me because I was under the impression that TT only supported futures trading. He said it just depends on whether your trading firm (or broker) has a data feed from an exchange that trades ETFs. If you have a data feed, then TT can connect via the FIX protocol. Well, after digging through TT's website, I could not find any mention of X_Trader's ability to trade ETFs. In addition, FWIW, I have never heard of any traders using TT for this purpose. Maybe the guy at Trading Technologies was right, but could someone confirm this? Does anyone have experience using X_Trader to trade ETFs (and if so, through what broker/firm)? Thanks!
