Your order is sold and before it hits the market, the HFT games your order for their benefit.
Even if you don't believe me, use logical thinking - why would anyone pay to get your orders before they hit the market if they wouldn't benefit monetarily?
Simple, they game you. When you transmit the order it first goes to whoever pays for it, only then it hits the market and by that time they have figured a way how to play it to their advantage. That's why they pay for order flow, it's not for nothing.
