The provided data indicates several discrepancies between sharp and soft bookmaker lines, suggesting potential pricing inefficiencies. Specifically, the 'Total - Away | Over 4.5' market shows significant EV, but this market is generally outside the scope of our core 'main markets' for robust quantitative analysis due to its higher variance and lower liquidity profile. Similarly, 'Total Corners (1st Half)' markets, while offering EV, are also not considered primary 'main markets' for the Early Alpha strategy. The strategy prioritizes high-volume, low-variance markets for consistent alpha generation.

While the raw EV percentages are high for some of these niche markets, the Early Alpha model is designed to detect robust signals in highly liquid and predictable main markets. Divergences in secondary markets, especially those with high odds (like 9.00 for Over 4.5 team goals), often represent higher variance and are less reliable for consistent edge. The absence of reverse line movement (RLM) also suggests that the market has not yet started to correct aggressively on these specific discrepancies, or that the sharp money is focused elsewhere.

1. Identified all provided odds discrepancies and calculated EV values.
2. Filtered out markets that do not align with the 'CRITICAL RULES' for 'main markets' (Match Winner, Over/Under 2.5, Over/Under 1.5, Over/Under 3.5, Both Teams to Score, Asian Handicap, Double Chance).
3. The 'Total - Away | Over 4.5' market, despite its high EV (44.44% and 22.22%), falls outside the defined main markets and involves high odds (9.00).
4. 'Total Corners (1st Half)' markets are also not considered main markets by the strategy.
5. No suitable 'main market' with a realistic EV (2-25%) and reasonable odds (1.30-5.00) was identified from the provided data.
6. Therefore, no 'back' or 'lay' signal can be generated under the strict parameters of the Early Alpha strategy.
