Common error
Avoid using "the window closed" when you actually mean "the window was barred". The former implies a completed action of shutting, whereas the latter implies an intentional prevention of entry. Additionally, in financial contexts, ensure you specify which window (e.g. IPO window or trading window) to avoid ambiguity.
