How Q-Score Works

Q = ((max_spread - your_spread) / max_spread)^2 x size

The reward formula is quadratic — orders closer to the midpoint earn disproportionately more.

  • Tighter spread = exponentially higher Q-score
  • Larger order size = linearly higher Q-score
  • One-sided orders get 1/3 the score
  • Orders beyond max spread earn zero

Your daily reward = (Your Q / Total Q) x Daily Pool

Reward vs Spread
