好奇想听听其他人的经验，尤其是在差价合约方面，当市场变得非常不稳定时。这些年我用过几家不同的经纪商，虽然大多数时候99%都没问题，但我注意到他们在处理极端市场波动时的表现差异很大。我说的不是大家预期的那种常见滑点，而是实际的执行问题——延迟成交，在重大新闻发布时，$EURUSD 或 $GBPUSD 等主要货币对的价差在几秒钟内变得异常大，甚至在流动性较差的资产上出现过短暂的“无报价”情况。
这让我质疑这些提供商真正能获得的流动性深度，尤其是在所有人都试图在同一买价或卖价成交时。这是普遍的经验，还是我只是运气不好选错了？你们用什么指标来衡量经纪商在危机发生 之前 的真实流动性能力？除了等待下一次市场崩溃，有没有什么实际的方法可以测试它？
CFDs are inherently risky during high volatility; expecting seamless execution when the underlying market is going wild is a bit naive. If you're consistently seeing absurd spreads or major delays, it's likely your broker's liquidity providers are bailing, or your broker just isn't well-capitalized enough to handle the strain.
I've definitely seen the same. Some brokers widen spreads to an unusable degree, effectively freezing you out of the market, while others seem to maintain decent liquidity even during wild swings. It makes a huge difference.
