There's just one catch as far as I understand when talking about buying through Fidelity f.ex. if you are buying less than 100 shares (this amount varies according to the price of the stock, IIRC it's like brackets of 10, 100 and 1000 something like that) then it's an "odd lot" and it won't affect the NBBO.
So most smaller trades by retail have absolutely no affect on the price.

Reply to comment by notausername86 in Is it just me, or is a a Market Makers' role in Order/Execution/Settlement confusing? Question: The CEO of Webull talked about their Market Maker, saying: "We're able to buy a share without driving up the stock 10% every time?" What does this work with Price Discovery & Supply & Demand? by ringingbells
