关于$EURUSD剥头皮交易与波段交易以及风险规模的问题

That's a great question and something I grappled with for a while. For me, it often comes down to the percentage of my account I'm willing to risk on any single trade, regardless of its duration. So, if my scalp trades risk 0.5% per trade, my swing trades might also stick to that 0.5%, but with a wider stop loss, meaning a smaller position size. This way, the dollar amount at risk is consistent, even if the leverage ratio looks different.
