Dota 2 betting strategies

Backtested on 4993 matches with historical odds
Odds are real historical figures averaged per match. Outcome probability is built walk-forward with Elo (no look-ahead). Starting bankroll is 1000 units. This is not investment advice.
Your strategy: Value on underdog (odds ≥ 2) · 2% of bankrollits recommendations show up on match pages
All results are computed on historical matches: probability is built walk-forward with Elo, and stake size scales off a 1000-unit bankroll. "Bankroll reset" sets how often the bankroll returns to its starting sum — profit is withdrawn, drawdown topped up.
