The provided data indicates significant pricing discrepancies between sharp and soft bookmakers, characteristic of early market inefficiencies. While several markets show positive Expected Value (EV), the 'Total Corners (1st Half)' markets are not considered main markets for the Early Alpha strategy due to their higher variance and lower liquidity, which can lead to less reliable CLV capture. The strategy focuses on high-volume, liquid markets where pricing errors are more consistently exploitable.

Specifically, the top EV opportunities listed pertain to first-half corner markets. Although the EV percentages are attractive, exceeding 20%, these markets fall outside the defined scope of the Early Alpha model's core focus (Match Winner, standard Over/Under, Asian Handicap, BTTS, Double Chance). The model prioritizes robustness and consistent edge capture over high-variance, niche market opportunities, especially when considering the 48-72h pre-kickoff window where liquidity might still be developing for these secondary markets.

1. Review provided odds comparison data, focusing on EV and market type. 2. Identify the highest EV opportunities: 'Total Corners (1st Half) | Under 4' (34.45% EV) and 'Total Corners (1st Half) | Over 4' (24.84% EV). 3. Cross-reference these markets against the 'CRITICAL RULES' for the Early Alpha strategy. 4. Rule 1 explicitly states: 'ONLY recommend MAIN MARKETS: Match Winner (1X2), Over/Under 2.5, Over/Under 1.5, Over/Under 3.5, Both Teams to Score, Asian Handicap, Double Chance. NEVER recommend Exact Score, Correct Score, or First Half Score markets'. 5. 'Total Corners (1st Half)' is not a main market as per the strategy's definition. 6. Therefore, despite the high EV, no actionable signal can be generated for these specific markets under the current strategy constraints. 7. Set signalType to 'avoid' as the identified high-EV opportunities are explicitly excluded by the strategy's rules.
