Hi guys, does anyone have an idea of which futures market out of 6e, 6a, 6b or es would fill limit orders the fastest? For example if my buy limit order was 5 ticks below the market. Then the market came down, touched my limit and reversed. Which of the futures markets would most likely fill the order? Also be good to know your reasoning. I assume it would not be the ES due to the saturation of HFTs which use limit orders. Thanks.
