Educational note: This article explains market structure and probability reading. It is not financial, legal or trading advice.
Normalize the contract
Before comparing prices, confirm that the event, deadline, source of truth and outcome definition match. Similar headlines are not enough.
Adjust your interpretation
- Use executable bid/ask prices.
- Consider fees and spreads.
- Check depth and recent volume.
- Account for resolution and withdrawal timing.
Research output
