I might considering doing some testing and playing around with the math some. Are you looking at charts or using the depth of market? If using charts, you may be able to look back and see how often your 2 tick moves would have yielded 4 ticks. If you can get your average winner to be 4 ticks and maintain your average loser at 3 ticks. Now you can have a 50% win rate and if consistent can goose the strategy with some size and make a pretty decent amount.
