Quick Answer

To buy Yes or No on Opinion.trade, open a market, read its resolution rules, select the outcome you believe is underpriced, enter an amount, review the order preview and confirm. A price of 0.65 is commonly read as roughly 65% implied probability, but it is a market price—not a promise that the outcome will occur.

This guide follows the current Opinion product documentation. The live order preview, market rules and applicable Terms take priority if the interface changes.

​
Before You Click Yes or No

The outcome label is only one part of the trade. Check all five items first: If any rule is ambiguous to you, do not place the order until you can explain how the market will settle.

​
Step-by-Step: Place a Yes or No Order

​
1. Open the verified app

Use app.opinion.trade and verify the address bar before connecting an account or wallet. Our official-links directory lists the maintained Opinion domains and social channels.

​
2. Find the market

Browse, filter or search for the event you want to trade. Open the market page rather than making a decision from a headline or preview card.

​
3. Read the complete rules

Confirm the outcome definitions, deadline, evidence source and exceptional cases. A belief about the real-world event is not enough if it does not match the written contract.

​
4. Choose Yes or No

  • Buy Yes when you believe the chance of the stated outcome is higher than the current Yes price implies.
  • Buy No when you believe the chance of the stated outcome not occurring is higher than the current No price implies.
This is a framework for reading the position, not a recommendation to trade either side.

​
5. Choose an order type

A market order prioritizes immediate execution against available liquidity. A limit order sets the highest price you are willing to pay and may wait, fill partially or never fill. Read Market Order vs Limit Order on Opinion.trade before choosing.

​
6. Enter the amount and inspect the preview

Review the outcome, order type, estimated execution price, number of shares, fee, potential payout and maximum amount at risk. Current Docs list a 5minimumorderanda5 minimum order and a 0.50 minimum fee, subject to live product conditions.

​
7. Confirm, then verify the fill

After confirmation, check whether the order is filled, partially filled or still open. A limit order resting in the book is not the same as a completed position. Open orders can be monitored and cancelled from the market or portfolio interface.

​
What Happens After You Buy?

You have two main paths:
  • Sell before resolution: If liquidity is available, you can reduce or close the position before the market ends. Your sale price can be above or below your entry price.
  • Hold through resolution: The winning outcome settles according to the published rules; the losing outcome can settle at zero.
The portfolio’s unrealized P&L changes with the market price. It is not final profit until the position is sold or settled. See Trade Before Resolution.

​
A Simple Example

Suppose Yes is offered at 0.65. Buying 10 Yes shares costs approximately 6.50beforefees.IfYesisthewinningoutcomeandeachwinningsharesettlesat6.50 before fees. If Yes is the winning outcome and each winning share settles at 1, the gross settlement value would be 10.IfNowins,thoseYessharesmaysettleat10. If No wins, those Yes shares may settle at 0. Actual execution and net result depend on fills, fees and the market’s final resolution.

​
Common Mistakes

  • Reading 65% as certainty rather than an implied probability.
  • Trading from the title without reading the resolution source.
  • Assuming the latest price is available for the entire order.
  • Confusing an open limit order with a filled position.
  • Ignoring the fee and maximum-loss fields in the preview.
  • Believing you must wait until resolution to exit.
  • Connecting through a link sent by an unverified account.

FAQ

You are buying an outcome share tied to the exact market rules. Read those rules carefully: the everyday meaning of the headline may differ from the contract’s settlement definition.
The interface may allow positions on either outcome, but each order should be evaluated independently for price, fees, liquidity and risk. Holding both sides does not automatically guarantee profit after execution costs.
You can submit a sell order before resolution, but execution depends on available buyers, the spread and order-book depth.
A limit order fills only when another trader matches your chosen price. It can remain open, fill partially or expire. Check Open Orders and available liquidity.
For a fully paid outcome-share purchase, the amount spent plus applicable costs is the central amount at risk. Always rely on the live maximum-loss preview for the exact order.
