How calls are scored
Backd never takes money, so every call is scored the same way: as if $10 was put on it at the price you got in at.
The $10 rule
A call at 58% pays $10 ÷ 0.58 = $17.24 if it's right, which is $7.24 profit. If it's wrong, it's −$10. The longer the odds, the more a right call is worth: Yes at 25% pays $40.
| Chance | $10 wins | Profit if right | If wrong |
|---|---|---|---|
| 90% | $11.11 | +$1.11 | −$10.00 |
| 75% | $13.33 | +$3.33 | −$10.00 |
| 58% | $17.24 | +$7.24 | −$10.00 |
| 50% | $20.00 | +$10.00 | −$10.00 |
| 33% | $30.30 | +$20.30 | −$10.00 |
| 25% | $40.00 | +$30.00 | −$10.00 |
| 10% | $100.00 | +$90.00 | −$10.00 |
Profit and right %
Profit is the sum across your settled calls. Right % is won ÷ settled. Both only count calls that have settled: open calls show what they're worth at today's price, but that's not on your record until the market resolves.
A 40% right record can be a very profitable one if the right calls were long shots. That's why profiles show both.
Void calls
If a market is cancelled, or resolves 50/50, the calls on it are void: neither won nor lost, and they don't count toward right % or profit.
Why not real stakes?
Two reasons. Backd is free, so there's nothing to stake. And a fixed $10 makes records comparable: a $5 caller and a $500 caller are ranked on the same terms, so the leaderboard measures judgement, not bankroll.
