Well if we’re averaging, sure. But that’s not what the parent is talking about. Moreover, what you’re describing isn’t a HFT strategy, it’s an investment strategy.

No, that is how you think about high frequency trades. Lots of trades in a small amount of time, with a tiny positive expectancy.

So Virtu profits on 51-52% of its trades. The type of math you are describing does not make any sense. Unless Virtu is significantly different from every other HFT firm, your idea of high asymmetry of profit and losses is not true.
