Glossary

Definitions used across the framework — consistent & measurable.

This glossary is the reference point for every dataset and episode. Definitions are standardised so outputs remain comparable across time and conditions. If a term appears on the Series or Public Data pages, it should be defined here.

  • If a word is unclear, search this page before asking in Discord.

  • Definitions here are written to be measurable, not poetic.

How To Use The Glossary
Core Terms
Term
Definition
Condition / Variable
A feature used to segment events into comparable groups (e.g., context, location, or state), allowing probabilities and performance to be measured conditionally rather than averaged.
Event
A precisely defined occurrence in price data that triggers measurement (the “thing that happens”), specified by objective rules so it can be identified consistently.
Expectancy (R-Multiple)
The average risk-adjusted return per opportunity, expressed in R-multiples (realised risk-to-reward ratios), combining both win rate and the distribution of wins/losses into a single measurable edge.
Market Regime/Market Structure
A classification of market conditions that groups periods where price behaviour is meaningfully similar, so results can be compared within similar environments.
Objective / Target
A predefined level or condition that defines “success” for an outcome, used as the reference point for measurement rather than a discretionary profit-taking decision.
Outcome
The measurable result observed after an event, defined in advance by explicit criteria.
General Terms (A -> Z)
Term
Definition
Binary Outcome
A yes/no definition of success for a hypothesis (e.g., “target reached” vs “not reached”), set before testing.
Conditional Probability
The probability of an outcome given specific conditions are present.
Expectancy
The average R-multiple per opportunity over many trades; positive expectancy implies a statistical edge.
Feature
A measurable attribute engineered from raw price data, used to describe an event or its context so outcomes can be compared across similar situations.
Hypothesis
A testable claim linking an event + conditions to an expected outcome, written so it can be proven wrong.
Liquidity
The availability of resting orders; practically, areas where price can move quickly due to clustered orders.
Overfitting
When rules match past data extremely well but fail forward because they captured noise, not a stable relationship.
R-Multiple
Profit or loss expressed in units of risk (R); +1R means you made the same amount you risked.
Sample Size
The number of observations used to calculate a metric; larger n (sample size) reduces noise and improves reliability.
Signal
A rule that triggers an action (or flags an opportunity) based on predefined conditions; a signal is not “edge” until validated.
Stop Loss (SL)
The predefined invalidation level where a trade is exited to cap loss.
Subset
A filtered portion of data defined by conditions.
Take Profit (TP)
The predefined target where profit is realised; usually tied to the hypothesis outcome definition.
