It starts from an event or market URL, checks the market and turns a plain-English hypothesis into a rule with a trigger and evaluation horizon that the user can edit before starting.

Review rules, prices and liquidity before the run. An explicit confirmation starts the paper test; checkpoints then collect matching observations over the defined intervals. The evidence summary can be promising, negative or inconclusive, with supporting figures and modeled costs. Preserve the original rule and result when trying a variation, rather than rewriting the earlier hypothesis after seeing its outcome. A result applies to its observed sample and cost model, and incomplete observations do not complete the horizon. Every plan remains paper-only: none connects a trading wallet or places live orders. ### Who it is for - Testing a specific market hypothesis. - Comparing separate strategy variations. - Learning to turn a vague idea into a repeatable rule. ## Features and coverage - **Market URL input** Start from a full event or market link. - **Market checks** Review rules, prices and liquidity before testing. - **Editable rule draft** Convert an idea into a trigger and evaluation horizon, then edit the draft. - **Explicit paper-test start** Review and confirm the rule before the run begins. - **Checkpoint observations** Follow matching observations over defined intervals. - **Modeled costs** Include cost assumptions in the reported result. - **Evidence summary** Read promising, negative or inconclusive findings with their supporting numbers. - **Saved research** Keep the original rule and result when testing a variation. ## Workflows with OddSage ### Test a price hypothesis Paste the market, define a price condition and horizon, review the draft and start the paper test. ### Investigate a negative result Judge the run by the observations it completed and the result after modeled costs. Keep the original rule intact so the result remains tied to the hypothesis you tested. ### Compare variations Keep the first test unchanged as the reference. Create another version for a single altered assumption, so the two records remain available for comparison. ## Pricing and total cost Free paper research is available, with paid capacity for repeated tests, scans and exports. Historical-test limits and AI-credit limits are separate; no plan enables live execution. ### Free $0 - Limited historical tests - 10 AI credits/day - Use your own model API key ### Researcher $29/month - Unlimited historical tests - 500 AI credits/month, with a 100/day limit - Parameter sweeps, scheduled scans and exports ### Pro $99/month - Researcher features - 2,000 AI credits/month, with a 400/day limit - Higher concurrency and bulk research ### Fees and usage costs - Using your own OpenAI, Anthropic or xAI key incurs charges from that model provider. ## Getting started **Before you start:** Results apply to the observed sample and modeled costs. 1. Paste the market URL. 2. Review the market check. 3. Describe a repeatable condition. 4. Edit the generated rule and its horizon. 5. Confirm the paper test. 6. Inspect observations, modeled costs and the saved result. No plan connects a trading wallet or places live orders. ## Useful links ### What to check - Results apply to the observed sample and modeled costs. - Incomplete observations are not a completed evaluation horizon. - Paper results do not validate live execution or wallet integration.

Simulation-only access across every plan means results cannot validate live execution or wallet integration. Based on documented features, setup and access terms.
