I had no fills on friday and no fills one day the week before and several one fill days. Fills seems to come and go with Open Orders and so does profitability. The recent lack of fills is a little surprising to me because the market has been volatile and that usually helps OO; more fills and better profitability.
As more people use the OO strategy it loses its effectiveness. Traders need an opening imbalance to make the strategy effective. The size of the gaps decreases, fewer big winners and more losers.
Look at the size of the opening prints, its sometimes about 20,000 to 50,000 shares for a stock that trades 2 million or more shares a day, it only takes a few Bright traders at 2,000 shares to make up a majority of the print. and all but a couple stocks that are good for the open orders print about 100,000 or less at the open and there is quite a small number of stocks that trade enough volume to use with open orders if you want to trade with any size. so 50 bright traders with 2,000 to 2,500 shares and the is no imbalance and 100,000 shares looking to exit right after the open.
The imbalances will return as some traders lose money with the open orders and move on to another strategy. or we get so much volatility that large prints creat big imbalances.
