Optimizing...The server is evaluating the current portfolio.
No portfolio can be generated from the current legs. Add at least two valid legs with decimal odds above 1 and estimated probabilities above the selected risk threshold.

Method

How it works

The optimizer creates candidate two-leg and three-leg simulations from manually entered odds and probabilities. It applies confidence adjustments, market-type weights, same-event correlation penalties, probability floors, long-shot limits, and fractional-Kelly caps before allocating the selected budget.

How to use this calculator

  1. 1Enter a budget and choose safe, balanced, or aggressive simulation mode.
  2. 2Add at least two legs with market, selection, decimal odds, and estimated probability.
  3. 3Set probability confidence and flag high-variance exposure where appropriate.
  4. 4Compare hit probability, EV, concentration, warnings, and maximum payout across the generated portfolio.

Educational example

Balanced portfolio example

A balanced simulation may allocate more budget to a lower-variance two-leg combination and a smaller amount to a higher-return three-leg combination.

The output is a comparison model, not a recommendation. Changing one probability or correlation assumption can reorder the entire portfolio.

Common use cases

Compare risk modes

See how probability floors and long-shot limits change allocation.

Stress-test assumptions

Reduce probability confidence to measure model sensitivity.

Control concentration

Review how much simulated stake depends on the same leg or event.

Limitations

No optimizer can turn uncertain inputs into guaranteed returns. The current public tool accepts manual data, does not place wagers, and must not be treated as personalized financial or gambling advice.

Frequently asked questions

Does the optimizer recommend bets?

No. It compares user-entered scenarios for educational analysis.

How is correlation handled?

The server model discounts same-event and overlapping market combinations using configurable penalties.

Are the displayed odds live?

No. Public calculations use manual inputs until an approved read-only provider is configured.
