More of a question than a comment, but how do Trading Fees [1] effect HFT and the market? I suspect that high volume trades over time could be seriously effected by the trends in these fees.

[1] e.g. NYSE Trading Fees, https://www.nyse.com/markets/nyse/trading-info#trading-fees

Most HFT players are market makers, not market takers. If you take a look at the fees in that link, the fees for liquidity taking are positive, i.e. $0.0027, whereas the fees for liquidity providing are negative, i.e. $(0.00150).

Exchanges offer rebates to market makers to incentivize market activity on their platform.
