After switching from payment-for-order-flow routes to direct market access at my retail broker, the most measurable improvement I saw was fill quality during fast moves. Before the switch, my short-dated options scalps often slipped, and about 31% of my exits filled worse than the mid-price, especially around open. After moving to direct access, that number dropped to 13% over the next eight weeks. One clear example was a same-day index options trade where earlier I would miss the price and watch the move run away; with direct routing, my orders hit where I expected, and my average trade hold time fell by 27% while win consistency improved. What stood out was not bigger wins, but fewer small losses caused by delays. Seeing orders reach the market directly changed how calm and predictable the whole process felt.
