Opportunity Analysis

The opportunities command identifies markets where:

High certainty: Price ≥85¢ YES or ≤15¢ YES (implies 85%+ confidence)
Meaningful payoff: Potential return ≥10% on capital
Sufficient liquidity: Orderbook depth supports reasonable position size

Formula: expected_value = probability * payoff - (1 - probability) * cost

A good opportunity has: EV / cost > 0.1 (10%+ expected return)
