@tradejs/strategy-dragon

TradeJS strategy plugin providing Dragon.

Strategy overview

Dragon detects a rare four-pivot reversal pattern in both directions:

1. head starts the directional move;
2. front foot ends its first impulse;
3. hump retraces 30–50% of the head-to-front-foot height;
4. rear foot is 10–15% of that height closer to the head than the front foot;
5. an entry becomes eligible when price closes through the projected head-to-hump trendline.

The bullish form uses high → low → lower high → higher low and enters long above a descending trendline. The bearish form is its exact mirror.

Signal geometry

The illustrations are schematic. Defaults use wick pivots, a two-bar confirmed fractal, a 100% measured-move target from the confirmed break, and a stop 10% of pattern height beyond the rear foot. Every tolerance is explicit in the strategy config so research can change geometry without changing detector code.

Install

yarn add @tradejs/strategy-dragon

Register the package in tradejs.config.ts:

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

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

The package exports strategyEntries, the Dragon strategy definition, manifest, default config, and AI adapter.

Development

yarn install --immutable
yarn checks

Publishing is beta-first and delegated to the pinned TradeJS-Workflows@v1 reusable workflow.

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, or Strategy Kit.
