How to use this glossary
A glossary is only useful if it answers the question you actually had. Ours is written for the moment you meet a term in the middle of something else: a broker's fee table, a platform setting, a margin email. Each definition therefore states what the term means and then what it changes for you.
Where a term has a UK-specific meaning — spread betting tax treatment, FSCS eligibility, the retail leverage caps — the definition uses the UK rule rather than a generic international one. That distinction matters, because most of the trading material online is written for markets with very different consumer protections.
- Definitions are one to two sentences, so you can scan rather than read
- Terms are grouped by the job they do, not alphabetically alone
- Regulatory terms link through to the full explanation of the rule
- Every entry has its own page for deeper reading and related terms
