Paper trading · Free until November 1, 2026
Win on a busted thesis and you feel like a genius. Lose on a sound setup and you abandon it. Opus is a paper-trading platform that separates the two: every trade captures your reasoning at entry, and every close is graded on the decision, not the outcome.

The ticket asks for one sentence on why before it lets you place the trade. No retconning the reasoning once you know how it went.
Entry timing, sizing, exit and market regime, graded. The thesis gets its own verdict: right, wrong, partial, or unverifiable, regardless of whether the trade made money.
The counterfactual replays the trade from real prices and says it in dollars. Then the P&L is split into price, time decay and volatility, so you know which one actually paid you.
Verticals, condors, calendars, diagonals, ratios and custom structures, with per-leg fills from the live Polygon chain and a worst-case loss in dollars before you place.
Place two or three paper trades this week, close at least one, and read the post-mortem. If the grade on your condor exit is wrong, we want that comment more than the signup.
Opus Options Trading is a paper-trading platform for education and practice. It is not a broker, does not hold funds, and does not give investment advice. Paper results do not predict real-money results.
