Dota 2 betting strategies

Backtested on 257 matches, odds modelled from ratings
Odds are modelled from the Elo rating (walk-forward, no look-ahead) with a bookmaker margin — the rating tracks the real pre-match line closely. Starting bankroll is 1000 units. This is not investment advice.
Your strategy: Underdog at odds ≥ 2.0 · 10% 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 "Bankroll reset" sets how often the bankroll returns to its starting sum — profit is withdrawn, drawdown topped up.
