Market Memory Forecast

Surface the historical analogs that most closely mirror the last 30 sessions on SPY

What is Market Memory?

Market Memory helps you discover historical periods that behaved similarly to what the asset has been doing recently, then displays how prices tended to evolve afterward. Use it to set context, frame scenarios, and stress-test plans.

Quick start

  • Pick a ticker and a lookback length that matches your timeframe.
  • Choose a similarity style that feels right for your use case.
  • Review the “Best Match” and the subsequent “Forecast” path as a scenario.

Why it’s useful

  • Provides historical context for the current tape.
  • Helps set expectations for ranges and drift.
  • Supports plan-making (entries, risk, take-profits) with real examples.

Good practice

  • Treat the forecast as a scenario, not a prediction.
  • Favor matches from comparable environments (volatility/liquidity).
  • Combine with risk controls (position sizing, stops, time-based exits).

Lookback

The recent price behavior we’re comparing to the past.

Understanding Market Memory

What is Market Memory?

Market Memory searches decades of price data to find historical stretches that behaved most similarly to the recent past (“lookback”). It then shows what unfolded after those analogs, giving you scenario context instead of a single forecast.

How to read the charts

  • Lookback: Cumulative return for the most recent window you selected.
  • Best Match: The historical period with the highest similarity score, aligned to today.
  • Forecast: How prices tended to evolve after that best match — use it for scenario planning, not prediction.

Practical applications

  • Scenario planning: Stress-test plans with historical context for ranges, drifts, and reversals.
  • Context: Quickly see whether current action is unprecedented or rhymes with previous regimes.
  • Idea flow: Spot setups for further research or risk adjustments.
