No-Loss Dutching
📖 What is No-Loss Dutching?
No-Loss Dutching (also known as Arbitrage or Surebet) is a strategy that guarantees profit regardless of the event's outcome. This happens when the sum of the reciprocals of the odds is less than 1.
In this situation, you can distribute your bet across all possible outcomes and have guaranteed profit, completely eliminating the risk of loss.
🔑 The Magic Condition: Sum of Reciprocals < 1
Guaranteed Profit if: Σ (1 / Odds_i) < 1
When the sum of the reciprocals of the odds of all possible outcomes is less than 1, you have an arbitrage opportunity with guaranteed profit.
📊 Practical Arbitrage Example
Consider a tennis match between two players with the following odds at different bookmakers:
- Bookmaker A: Player 1 Odds = 2.10
- Bookmaker B: Player 2 Odds = 2.20
Sum of reciprocals calculation:
Sum = 1/2.10 + 1/2.20 = 0.476 + 0.455 = 0.931 (< 1)
With $100 to bet:
- Bet Player 1 = (100 / 0.931) × 0.476 = $51.13
- Bet Player 2 = (100 / 0.931) × 0.455 = $48.87
- Guaranteed return = $107.37
- Guaranteed profit = $7.37 (ROI 7.37%)
