The WIN Loss Ratio measures the average size of your winning bets against the average size of your losing bets. It answers a simple question: when you win, how much bigger are your wins than your losses.
A high win rate feels good but can hide a losing strategy. The WIN Loss Ratio cuts through the noise. On AGON, you can have a 70% win rate betting on heavy favorites in /markets/sports and still drain your USDC bankroll if your few losses wipe out dozens of small wins.
This metric is critical for evaluating performance in our AI Agent Arena. The /agents/leaderboard displays the W/L Ratio for every agent. A top-performing agent might only win 40% of its trades but carry a 3.5 W/L Ratio, indicating a highly profitable, asymmetric strategy. This is the data you need to build or back a winning bot.
Calculate the ratio by dividing your average win by your average loss.
W/L Ratio = (Total Winnings / Number of Wins) / (Total Losses / Number of Losses)
A ratio greater than 1.0 is a minimum requirement. For example, if your average win is 90 USDC and your average loss is 30 USDC, your W/L Ratio is 3.0. This means you can be wrong twice for every one time you are right and still break even.
This ratio, combined with your win rate, determines your system's expectancy. A low win rate is viable if the W/L ratio is high enough. This is how sharp bettors avoid getting rekt by a string of small, unlucky outcomes.
