Leverage changes on a Friday afternoon
An email arrives on Friday: leverage reduced from 1:500 to 1:100 ahead of the weekend and "high impact events." It sits unread.
Margin requirements jump overnight. Any position still open might suddenly need five times the margin, and if free margin cannot cover it, the platform starts closing trades.
Scalpers running tight on free margin to maximise size are the most exposed, and also the ones least likely to hold anything through the weekend, which makes the risk feel irrelevant until the one time it is not.
A buffer of free margin bigger than strictly needed costs a little in potential size and removes one whole failure mode.
Notices also tend to be vague. "Leverage may be adjusted in line with market conditions" appears in the terms, and the exact schedule is rarely published. Some brokers apply it automatically based on position size, which means a larger trade can have a lower leverage cap than a smaller one on the same account.
Checking the leverage tiers in the account settings, and noting whether they depend on volume, takes a few minutes and answers most of the questions.
A reasonable routine is a quick scan of broker emails every Friday before the close, looking for anything with the words leverage, margin, or maintenance. It takes thirty seconds and removes a category of unpleasant surprise.
Has a leverage change ever forced a trade closed unexpectedly?
