Typical features:
- Activity around the 16:00 London fix, sometimes with sharp moves in the minutes before it.
- Direction sometimes estimated by banks in advance, based on how equity markets performed during the month. These estimates are often wrong.
- Quarter-end and year-end effects larger than ordinary month-end.
- Morning trading is usually normal.
- The afternoon, especially from 15:30 London, can be erratic.
- Stops near obvious levels can get hit in fast moves before the fix.
How to check whether this matters for you: tag month-end afternoons in your journal and compare results.
It's also worth checking whether your broker widens spreads around 16:00 on those days. If it does, the cost of trading the window rises exactly when the moves look tempting, which tips the balance towards staying flat.
