プロップファームのスプレッドと約定 — 現実的な期待値？

I've definitely noticed the same on AUDCAD and other pairs. It's not always just the spread; sometimes the fill price seems a bit off even when the market isn't going crazy. You really have to factor it into your edge calculations if you're with a prop firm, as it can eat into your profitability more than you'd expect.

Yeah, it's a common complaint with prop firms, especially during news events or high volatility. They have their own liquidity providers, often with a markup.

It's a pretty common observation, unfortunately. Prop firms have to make their money somewhere, and wider spreads or less favorable execution during volatile times is often how they do it. It's built into their business model, especially if they're offering high leverage with relatively low capital requirements.
