Which guides should we write next?

Our guides run from pip values to the carry trade and how floating exchange rates began. We want the next ones to answer questions members actually have.

Suggest a topic and, if you can, the specific question you couldn't find a clear answer to. "Something about options" is hard to act on; "how does an FX option's price change as expiry gets closer?" is easy.

We'll use this thread to choose what to write next.
