@tradejs/strategy-diamond

TradeJS strategy plugin providing Diamond on the 15-minute timeframe.

Strategy overview

Diamond detects a reversal pattern in both directions from six confirmed fractal pivots:

1. the first high and low establish the left side;
2. the next high and low move farther apart and form the central top and bottom;
3. the final high and low move closer together and form the contracting right side;
4. the projected right boundaries must converge ahead of the pattern;
5. an entry becomes eligible after price closes through the boundary opposite the preceding trend.

A bullish Diamond requires a falling approach and confirms above the descending upper boundary. A bearish Diamond requires a rising approach and confirms below the ascending lower boundary.

Signal geometry

The illustrations are schematic. Defaults use wick pivots, a two-bar confirmed fractal, a 100% measured-height target from the confirmed break, and a stop 10% of pattern height beyond the last opposite-side pivot. Expansion, contraction, central-axis alignment, left/right symmetry, preceding-trend strength, apex distance, and breakout freshness are explicit config fields so research can change geometry without changing detector code.

The detector supports direct breakout, next-close acceptance, and retest entry modes. close_acceptance is the default.

Install

yarn add @tradejs/strategy-diamond

Register the package in tradejs.config.ts:

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

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

The package exports strategyEntries, the Diamond 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.
