Trading Rules
Critical: ALWAYS confirm with the user before placing any buy or sell order.
Before executing a trade, show the user:
- Ticker
- Side (YES or NO)
- Count (number of contracts)
- Price (in cents)
- Total cost = count × price cents = $X.XX
Price format:
- Prices are in cents (1-99)
- 65 cents = $0.65 per contract
- Minimum: 1 cent, Maximum: 99 cents
Payouts:
- All contracts pay $1.00 (100 cents) if correct, $0 if wrong
- YES at 65¢: costs 65¢, pays $1.00 if YES wins → 35¢ profit per contract
- NO at 35¢: costs 35¢, pays $1.00 if NO wins → 65¢ profit per contract
- YES price + NO price ≈ 100¢ (spreads cause small deviations)
Before selling: Verify the user holds the position by checking portfolio first
