Market Lab · Memory

Learn by comparing today with historical contexts.

Double C reconstructs historical closes with no-lookahead rules. It compares similarity, temporal diversity, sample sensitivity, and which features explain the analogy.

Each question is built from current canonical evidence. The server validates the answer and awards XP; the browser does not decide the result.

Educational market memory

Today's BTC resembles…

Double C finds historical closes with a context similar to today. Similarity supports comparison; it does not mean the future will repeat.

Finding comparable contexts…

Cross-cycle comparison

Similar contexts from different periods, not only the nearest matches.

Double C starts from the similarity ranking and creates a second time-diversified sample. This helps reveal when an interpretation depends on one narrow market period.

Finding temporal diversity…

Sample sensitivity

Does the historical story change when the sample changes?

Compares the nearest-analogue distribution with the time-diversified sample. If they differ, Double C exposes sample sensitivity instead of choosing the more attractive story.

Comparing samples…

Analogue explainability

What actually makes these periods look similar?

Compares which features remain among the closest in both nearest and cross-cycle samples. This explains the analogy without using future outcomes.
