你们是如何根据波动性飙升调整大宗商品头寸规模的？

最近一直在交易一些能源产品，主要是 $NG 和 $CL，我发现当波动性突然加剧时，很难保持每笔交易一致的风险。我通常每笔交易固定的美元金额，在大幅波动时可能导致头寸过小，如果我不能及时调整止损，则可能导致头寸过大。你们是使用像ATR这样的指标来动态调整头寸规模，还是更多地依靠手动、凭“感觉”进行调整？

Yeah, it's definitely a challenge. I tend to use a percentage of my account value per trade and then factor in the ATR to calculate the number of contracts. It's not perfect, but it helps normalize the risk across different volatility regimes.

For commodities, especially $NG and $CL, fixed dollar risk is often impractical. I use ATR to size, but I also have a cap on how much I'll risk on any single trade, regardless of the ATR reading. Helps prevent getting blown out on extreme moves.
