@tradejs/strategy-trend-shift

TradeJS strategy plugin providing TrendShift.

Strategy overview

TrendShift builds a volatility-adaptive trend band from smoothed slope and long-horizon ATR, then trades confirmed flips of that band. Signal-body and ADX filters qualify the change, while band and ATR geometry define invalidation, targets, and optional opposite-flip exits.

Logic at a glance

Signal on an example chart

The volatility-adaptive band follows the smoothed bearish slope until a qualifying close flips the trend state; body and ADX rules decide whether to enter.

The illustration is schematic, not market data. Exact thresholds, confirmation rules, and risk parameters come from the active TradeJS strategy config.

Install

yarn add @tradejs/strategy-trend-shift

Register the package in tradejs.config.ts:

import { defineConfig } from "@tradejs/core/config";

export default defineConfig({
  strategies: ["@tradejs/strategy-trend-shift"],
});

The package exports strategyEntries for the TradeJS plugin loader together with its strategy definitions, manifests, default configs, and public AI/ML adapters. Strategy implementation changes are released from this repository, independently of the TradeJS engine.

Development

yarn install --immutable
yarn checks

Publishing is beta-first and delegated to the pinned TradeJS-Workflows@v1 reusable workflow. A relevant push publishes a unique prerelease and moves the npm beta tag only after the repository checks pass and the published tarball imports successfully in a clean npm consumer. The current verified beta is promoted to one stable latest release by the weekly automation; production never consumes prereleases.

Keywords: ai, claude, codex.

Runtime host contract

All @tradejs/* runtime packages are peer dependencies. The consuming TradeJS Project owns their exact installed versions and package manifest, so this package never loads a hidden nested engine, types package, indicator package, or Strategy Kit. Repository builds use matching dev dependencies only.
