Glossary

Key terms used throughout the FORJ platform.

Action​

Something your strategy does when a transition fires — for example, executing a trade, updating a variable, or logging output. Actions run after all conditions on the transition have passed. See Actions Manager.

Alert​

A notification triggered by strategy activity — a state change, a condition evaluation, an action firing, or an incoming event. Alerts can be delivered in-app, by email, SMS, or webhook. See Alerts.

Candle​

A block of market data over a fixed time interval containing Open, High, Low, and Close prices. Your strategy receives a New Candle event each time a candle closes for its subscribed data stream.

Candle Series​

A time-ordered sequence of candles for a specific instrument and timeframe. FORJ stores candle history per physical data stream.

Condition​

A true/false rule that must pass for a transition to fire. Conditions compare values like indicator readings, context variables, or event fields. Multiple conditions on a transition are combined with AND or OR logic. See Conditions Manager.

Context​

The set of variables and configuration that a strategy carries. Context includes user-defined variables, indicators, and internal state. It persists across events and can be read or modified by conditions and actions.

CRUCIBLE​

The FORJ backtesting tool. Upload historical candle data and replay it through your strategy to evaluate performance before going live. See CRUCIBLE.

Data Source​

An external system that sends market data into FORJ. Supported types include TradingView webhook alerts and generic HTTP webhooks. See Data Sources.

Data Stream​

A canonical representation of incoming data, identified by instrument, timeframe, venue, and series kind. Multiple data sources can feed the same stream.

Event​

Any signal that a strategy listens for. Common types include New Candle events (from candle streams) and Custom Events (sent via webhook with a name and payload).

Event Series​

A data stream that carries custom events (as opposed to OHLCV candles). Useful for external signals like news triggers or third-party alerts.

Global Event Handler​

A transition defined at the strategy level (not on a specific state) that fires from any state when its trigger matches. See Global Event Handlers.

HEARTH​

The FORJ dashboard. Shows all your strategies as tiles with real-time status, quick actions, and filtering. See HEARTH.

Indicator​

A derived calculation from price data — for example, EMA, RSI, or Bollinger Bands. Indicators are subscribed to per strategy and their values are available in conditions and actions. See Indicators.

Initial State​

The state your strategy starts in when first enabled. Only one state can be marked as initial.

The passwordless sign-in method used by FORJ. You enter your email and receive a one-time link that logs you in. Links expire after 5 minutes.

Physical Data Stream​

The internal canonical representation of data flowing into FORJ, uniquely identified by workspace, series kind, mapping signature, instrument, timeframe, and venue.

Plan​

Your subscription tier in FORJ. Plans determine how many strategies, data sources, and other resources your workspace can use. See Plans & Pricing.

SMITH​

The FORJ strategy editor. A visual canvas where you create and edit strategies by defining states, transitions, conditions, actions, and indicators. See SMITH.

State​

A phase of your strategy's operation — for example, "Idle", "Scanning", or "In Position". Each state can have entry/exit actions and outgoing transitions to other states.

Strategy​

The complete configuration of states, transitions, conditions, actions, and context that defines how your system reacts to market data. Each strategy runs independently within a workspace.

Strategy Tile​

A card on the HEARTH dashboard representing a single strategy. Shows the strategy name, current state, enabled status, and provides quick-action buttons.

Transition​

A connection between two states that defines when and how the strategy moves from one phase to another. A transition specifies a trigger event, optional conditions, and optional actions. See Transitions Manager.

Workspace​

Your isolated environment in FORJ. All strategies, data sources, alerts, and backtests are scoped to a workspace. See Workspaces.
