# @tradejs/strategy-double-tap

TradeJS strategy plugin providing `DoubleTap`.

## Strategy overview

`DoubleTap` detects double bottoms and double tops from replayable pivots,
validates tap similarity, spacing, symmetry, and pattern height, and trades the
neckline through breakout, close-acceptance, or retest entries. Stops and
targets come from the pattern's own geometry.

## Logic at a glance

## Signal on an example chart

The example shows two comparable pivot lows, their intervening neckline, and the confirmed neckline break that activates the bullish reversal.

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

## Install

```bash
yarn add @tradejs/strategy-double-tap
```

Register the package in `tradejs.config.ts`:

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

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

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

```bash
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.
