I use Market Replay on Ninja Trader to practice my day trading after the market has closed. Invariably and consistently, the Market Replay data gives me better set-ups. Trades that appear very obvious on the MR data don't even appear on the live data feed. My live data feed is CQG. I have attempted 2 or 3 times to ask Ninja Trader who provides this data, but I can't seem to get an answer. I don't know much about data feed. So I'm at a disadvantage. Perhaps someone can help me understand this. Is it possible to find out who NT uses for their MR data feed, and it is possible for me to seek out that data provider and use it for my live data feed?
