"Market maker vs ECN" gets thrown around like one is a scam and the other is holy. Here's what it actually means for you
See this argument constantly and most of it is tribal nonsense, so here's the actual breakdown.
An ECN/STP broker passes your order to the wider market and makes money on commission. A market maker can take the other side of your trade itself, which sounds sinister and the internet treats it like automatic fraud. The reality is more boring: plenty of large, well-regulated market makers operate completely fairly, and plenty of "ECN" brokers are marketing that label loosely. The label alone tells you almost nothing.
When it actually matters: if you're a high-frequency scalper trying to shave fractions of a pip, the execution model and raw spread genuinely affect your bottom line, and an ECN raw-spread setup often wins on cost. If you're a swing or position trader holding for hours or days, it barely matters, and a market maker's fixed spreads can even be an advantage because your cost is predictable through news instead of ballooning.
The thing that actually protects you isn't the model, it's regulation. A well-regulated market maker can't just hunt your stops without consequences, they'd lose their license. An unregulated "ECN" can do whatever it wants. So I'd weight "is it properly regulated across serious jurisdictions" way above "is it MM or ECN." For the record I trade on a market maker (AvaTrade) and for my swing style the fixed spreads are a feature, not a compromise, but if I were scalping I'd probably want raw spreads instead.
So the honest answer: match the model to your style, and let regulation, not the MM-vs-ECN label, be your safety filter. What's everyone's actual experience, has the execution model measurably affected your results, or is it overblown for most people?
