Hey I was wondering if any traders can help me out. I trade momentum nasdaq stocks but thought I would have a play around today trying to capture the spread on SIRI. It looks like everyone else is doing it! lol. Have attached a 1min chart of this lunchtime's price action where price stayed between 2.11 & 2.12 for the best part of 90 mins. I was just trying to get filled on a limit order buy 2.11 and sell 2.12, capture the spread and the rebates from the limit orders. routed through BATS, it was easy to get filled on one side but I couldn't get filled on the other side. Now I am guessing the reason why I am not getting filled is that either I am using the wrong order route or I am never at the front of the queue (or both!). So can any smart traders advise me how people are doing this? Thanks in advance londonkid.
