Madrid Open: Janice Tjen vs Liudmila Samsonova

How to read the numbers

Implied / market-implied YES

The probability of YES implied by current traded prices (mid or last). It is what participants are paying for, not a claim about real-world odds.

Model estimate

A rule-based heuristic from the signal engine when a rule sets one, not a black-box forecast. Some signals only describe liquidity or spreads and may show no model estimate.

Edge / gap

The difference between the model estimate and market-implied, in percentage points (model minus market for YES). Filters may use “largest gap.” This is informational only-not trading advice or guaranteed advantage.

Stance (above / below / near estimate)

Compares market-implied to the model estimate when both exist. Labels are not buy or sell recommendations.

Confidence

A simple UI clarity label for signals (not a prediction). It summarizes the signal’s own magnitude/quality metrics into one of: Low, Mid-low, Mid, Mid-high, or High.

Volume

Reported trading activity for the market, for context on size and liquidity.

Change & sparklines

Movement in market-implied YES over the window labeled on the card-often 24h where data allows.

Signals

Rule-based flags from ingested public data. They are not trade recommendations.
