Meta-Signal EV Synthesizer

Overview

This pillar combines your probability estimates with live market odds to calculate the Expected Value (EV) of a position. It transforms prediction from a game of being right to a discipline of being profitable.

What It Does

The synthesizer ingests a probability estimate, either from another pillar or your own analysis, and compares it against the current market price. It then computes the risk-adjusted expected value for both 'Yes' and 'No' sides of a market. This determines if the potential payout justifies the risk based on your belief.

Why It Matters

A correct prediction can still be a bad position if the price is too high. This pillar provides the crucial final step in any analysis, ensuring you only deploy capital in markets that are mathematically profitable over the long term.

How It Works

First, you provide a probability for an outcome (e.g., a 70% chance). The pillar then pulls the current market price (e.g., 65 cents). It calculates the EV for a 'Yes' bet and a 'No' bet, presenting a clear signal if one side offers a significant positive value.

Methodology

The core calculation uses the formula: EV = (Probability of Winning * Potential Profit) - (Probability of Losing * Potential Loss). For a 'Yes' bet, this is (P_win * (1 - Price)) - ((1 - P_win) * Price). The pillar uses a default conviction threshold (e.g., EV > +0.05) to trigger a positive signal, filtering out low-value opportunities.

Edge & Advantage

It provides a systematic, mathematical framework for position selection, preventing emotional trades and focusing solely on identifying and exploiting mispriced market odds.

Key Indicators

• Expected Value (EV)

  high

  The calculated average profit or loss of a bet if it were made many times.

• Value Threshold

  high

  The minimum positive EV required to signal a potentially profitable bet.

• Price vs. Probability Gap

  medium

  The difference between the market's implied probability (the price) and the input probability.

Data Sources

• Prediction Market APIs

  Provides the real-time market prices (odds) required for the EV calculation.

• Other Pillar Outputs

  Consumes probability estimates from other analysis pillars as a key input.

• User-Defined Probabilities

  Allows users to input their own probability estimates for custom analysis.

Example Questions This Pillar Answers

• → Which side of the 'Will this movie gross over $100M?' market offers positive expected value right now?
• → Given a 60% chance of a rate hike, are the market odds of 55% offering a sufficient edge to invest?
