ทำความเข้าใจ Risk-Reward ในสัญญา Kalshi

The ratios are sound, but the win rate is just as critical. A 1:3 ratio with a 20% win rate is going to lose money consistently. You need to tie your risk-reward directly to your historical edge.

While the general principle holds, Kalshi's binary nature and how probabilities are priced into contract values often make direct risk-reward ratios less straightforward than with typical equities. The 'risk' is always the full contract price if it goes to zero, regardless of potential payout.

That's a really clear explanation. I've been trying to get my head around risk-reward on Kalshi, and seeing it broken down with those examples makes a lot more sense. Do you find that it's generally harder to find those 1:2 or 1:3 ratios on Kalshi compared to other markets?

I agree on the fundamental importance of risk-reward, but focusing purely on the ratio overlooks the probability of the event itself. A 0.5:1 might be acceptable if the win probability is extremely high, say 90%.
