Hello traders, I'm trading the E-MINI S&P and I noticed that a lot of data feed providers looks good on candlesticks but when it comes to bid ask information they are full of errors. I was using esignal as a data feed but I noticed that it's impossible to use for bid ask. now i'm trading with ricxa flow from www.ricxa.com with iq-feed which is looking very good. I want to try other data feeds aside from qi-feed so I can choose the best & cheap one, if you know other data providers I would appreciate it very much Thanks.
