Buying a position means purchasing shares that pay out if a specific outcome occurs. On Vistadex, you can buy YES shares (betting an event will happen) or NO shares (betting it won’t).

​
Understanding Share Prices

Share prices reflect the market’s implied probability of an outcome: If you buy YES shares at $0.30 and the event happens, each share pays out $1.00.

​
Example Trade

Market: “Will Event X happen by December 31?”
  • Current YES price: $0.50
  • You spend: $100 USDC
  • Shares received: 200 YES shares
If YES wins: Your 200 shares pay out $200 → $100 profitIf NO wins: Your shares are worth $0 → $100 loss

​
After You Buy

Your new position appears in your portfolio immediately after the transaction confirms. From there you can:
  • Hold: Wait for market resolution
  • Sell: Exit your position early if you change your mind or want to lock in profit/loss
  • Buy more: Increase your position if your conviction grows
