Welcome to BabyPips @USA1791
Your username suggests you live in the US. If that's the case, please note there are currently only four brokers authorized to offer retail forex trading to US residents precisely because of the strict regulatory requirements we have to meet which include accountability for the price where each customer transaction is executed.
Unfortunately, you're not alone in having this misconception about market makers.
It's worth noting that for institutional traders, FOREX.com's parent company GAIN Capital offers ECN solutions through the GTX marketplace. However, at the retail level, we have always been open about our role as the market maker for the trades placed by our clients.
We feel no reason to hide this fact, because at retail trade sizes, we believe market making is the best way to provide customers with reliable pricing while effectively managing our own risk. We are fully accountable for every execution and don't outsource that responsibility to a third party.
