SAFE Update - Better Calibrated Probabilities
SAFE now models regime dynamics for better calibrated touch probabilities.
We have made a major upgrade to the SAFE engine.
Until now, price touch probabilities (+2%, +5%, +/-10% in N days) were calculated assuming an “average” distribution of returns.
Now, SAFE explicitly models market regimes and the transitions between them.
What this means in practice
- The market is no longer treated as “the same every day”.
- A regime (range, down fast, low vol, etc.) can persist or change with a certain probability.
- Simulations respect this dynamic, not just raw statistics.
Validation
We validated the upgrade strictly statistically, using Brier score on events (touch / no-touch), not PnL.
Result: better calibrated probabilities, especially for rare events and longer horizons.
What stays the same
- The daily output looks the same.
- The interpretation remains the same.
But what is behind it is now a process model, not just a distribution.
Small change in numbers. Big change in meaning.
Also, the model was retrained, therefore small adjustments will be visible in the chart.
Stay SAFE!
