SHEET 48.5 — BROKERS FOR PAPER TRADING
A good options simulator models spreads, greeks, assignment and slippage closely enough to build real habits. A bad one teaches you to expect perfect mid-price fills that never happen live.
Some partner links are affiliate links. GiottoO may earn a commission at no extra cost to you. Sponsored placements are always labeled. Partner compensation never influences trade scores or research outputs.

What's inside
Realistic fills
Simulated fills that respect the bid/ask spread — not instant mid-price magic — build correct expectations for live trading.
Multi-leg support
Paper trading verticals, iron condors and calendars as single tickets mirrors how you'll actually trade defined risk.
Greeks & assignment
Seeing position greeks evolve and experiencing simulated assignment prepares you for the parts that surprise new traders.
Same UI as live
A simulator that shares the live platform's order tickets means no relearning when you switch to real capital.
How we evaluate brokers for paper trading
These are criteria, not rankings — we publish the rubric and let you weight it for your account. Broker-by-broker detail lives in the full comparison.
Fill realism
Whether simulated fills respect spreads and liquidity or grant unrealistic mid-price executions.
Multi-leg fidelity
Support for spreads, condors and calendars as combined tickets with net pricing.
Greeks & assignment
Whether the simulator shows greeks and models early assignment realistically.
Parity with live
How closely the paper UI and order flow match the funded platform.
