If I put a sell order on the market at 12:00 the only impact is the sales price. If it executes at 1PM or 2PM it makes zero difference to me as I can only access money at the end of the day. So, I only gain liquidity if I would have been otherwise unable to sell by the end of the day. Therefore, I don't gain liquidity from HFT.
