Strategy

A strategy is the decision-making unit in TradeJS.

On each candle, a strategy decides whether to:

  • skip: do nothing and record an optional reason
  • entry: create a signal and an order plan
  • exit: close or manage an existing position

The shared runtime handles the surrounding work: market data flow, signal enrichment, optional AI/ML gates, order execution, hooks, and artifact storage.

TypeScript Strategies​

TypeScript strategies usually use StrategyAPI and return decisions through helper methods such as strategyApi.skip(...), strategyApi.entry(...), and strategyApi.exit(...).

Use TypeScript when you want strong typing, custom state machines, custom figures, or deeper runtime integration.

Pine Script-Inspired Strategies​

TradeJS can also run Pine-backed strategy modules where the Pine source stays in a dedicated .pine file and TypeScript orchestrates runtime behavior.

Use this when you are porting or comparing Pine Script-inspired workflows.

Built-In Strategies​

The non-empty @tradejs/base preset installs independent strategy packages for:

  • Breakout
  • TrendLine
  • ReverseTrendLine
  • TrendShift
  • TrendFollow
  • DoubleTap
  • LiquidityTails
  • LiquidityZones
  • StructureZones
  • AdaptiveTrendChannel
  • AdaptiveMomentumRibbon
  • MaStrategy
  • VolumeDivergence
  • MarketFlushReversal
  • VolatilityCompressionBreakout
  • RelativeRotation
  • CupAndHandle
  • HeadAndShoulders
  • Grid
  • GridClassic
  • HyperliquidConsensus

TrendLine and ReverseTrendLine share @tradejs/strategy-trend-line; every other strategy has its own package and repository. Built-ins are useful examples, but they are still strategy code that needs your own validation.

See the built-in strategy catalog for the grouped list, data requirements, and per-strategy references.
