As far as news no, but based on your order book which shows your customer buys and sells, yes. You can pretty much see where it is heading and when to accumulate based on your book, if you see a boatload of buys coming in for execution you can pretty much bet other MM's see the same which is why you see morning gap ups sometimes, then when you see the buys start to slow up and sells start to come in you know it's time to stop accumulateing and prepare for a retrace in PPS. It's like haveing a 10 minute window into the stocks future.
