The SEC has endorsed HFT because it boosts liquidity, despite objections from certain market players over the practice’s unfairness. This is so that other traders may execute their trades more quickly and at more consistent prices because HFT firms constantly place buy and sell orders. More efficient markets and smaller bid-ask spreads should result from this. On the other hand, some detractors contend that HFT companies might quickly pull out of transactions during times of market stress, increasing volatility and making it more difficult for other traders to enter or exit their holdings.
