SHEET P-01 — OPTIONS BROKERS
A factual side-by-side of five broker archetypes serious options traders actually consider. No 'best broker' claims — just the dimensions that matter for defined-risk trading, so you can decide for yourself.

What's inside
Commissions & fees
Per-contract pricing, open/close asymmetry, per-leg caps, index option surcharges and assignment or exercise fees. Small differences compound fast for spread traders running four legs at a time.
Spread approval levels
Defined-risk spreads usually require an intermediate approval tier. Check what each level unlocks, what the application asks, and whether spreads are allowed in IRAs.
Margin & buying power
How the broker computes buying-power reduction on spreads, whether it supports portfolio margin, and how it handles early assignment on short legs.
API access
If you automate research or journaling, API depth matters: order routing, options chains, streaming quotes, and paper-trading endpoints differ enormously between brokers.
Platform & tools
Options chain usability, probability and Greeks display, multi-leg order tickets, roll tools, and whether the mobile app can actually manage a spread under pressure.
Education & support
Approval-level guidance, options education content, and how fast support resolves an assignment or exercise question when it is time-sensitive.
