All engines communicate through a central **Event Bus** (EventEmitter pattern). Every event is logged and can be monitored in real-time via WebSocket.

## Core Engines

| Engine | Purpose | Key Outputs |
|--------|---------|-------------|
| **Structure Engine** | Detects HH/HL/LH/LL, BOS, CHoCH, FVG, Order Blocks | Market structure, trend direction, structural shifts |
| **Liquidity Engine** | Finds equal highs/lows, stop clusters, session levels, sweeps | Liquidity pools, sweep confirmations |
| **Bias Engine** | Multi-timeframe directional bias with conviction scoring | HTF bias, intraday bias, conviction 0-100, alignment score |
| **Macro Engine** | Tracks DXY, US10Y yields, risk sentiment, news proximity | macro_bias (bullish/bearish/neutral gold), macro_risk level |
| **Volatility Engine** | ATR calculation, spike detection, regime classification | ATR, volatility regime (low/normal/high/extreme) |
| **Risk Engine** | Position sizing, drawdown monitoring, halt triggers | Lot size, risk %, pass/fail gate for every trade |
| **Execution Engine** | Combines all engines to generate trade signals | Full trade plan: entry, SL, TP1/TP2/TP3, position size |
| **Performance Engine** | Win rate, expectancy, Sharpe, monthly breakdown | Comprehensive performance metrics and trade log |

## System Modes

| Mode | Name | Behavior |
|------|------|----------|
| 1 | **Advisory** | Full analysis pipeline runs, signals logged, no execution |
| 2 | **Semi-Automated** | Signals generated + automatic TP/SL/trailing management |
| 3 | **Fully-Automated** | Autonomous execution: signal → order → manage → close |
| 4 | **Risk-Off** | Monitoring only, no signals generated |

Set the mode in `data/state.json` or via WebSocket command. Always start in Mode 1 for validation.

## Risk Rules (Non-Negotiable)

These hard rules are enforced by the Risk Engine and cannot be overridden:

- **Max 2% risk per trade** — Position sized via `(Balance × Risk%) / StopDistance`
- **Max 5% daily exposure** — Cumulative open risk capped
- **3 consecutive losses → halt trading** for the session
- **Volatility spike → reduce size 50%** (extreme = 75% reduction)
- **Spread widening → block entry** (symbol-specific thresholds)
- **High-impact news < 20 minutes → block all entries**
- **Equity drawdown > 8% → halt trading** until manual resume
- **API error on order → cancel, do NOT retry**
- **Broker disconnect → close all positions immediately**

## Trade Management Protocol

1. **TP1 at 1.5R** → Partial close 40% → Move SL to break-even
2. **TP2 at 2.5R** → Partial close 30% → Trail SL under structure
3. **TP3 at 4.0R** → Close remaining 30% → Log trade to performance

## Entry Conditions (All Must Pass)

For the Execution Engine to generate a signal, every condition must be true:
1. Bias conviction ≥ 65/100
2. Alignment score ≥ 0.6
3. Liquidity sweep confirmed (aligned with direction)
4. BOS or CHoCH confirmed in trade direction
5. Session = London or New York (kill zones preferred)
6. Macro risk = low or medium
7. Spread within threshold
8. No news block active
9. Daily loss below 80% of limit
10. Consecutive losses < 3

## File Structure

## Installation

### Step 1: Deploy to OpenClaw

### Step 3: Configure Environment

Create a `.env` file in the skill root with the following variables:

**MetaAPI**: Sign up at https://metaapi.cloud and connect your Fusion Markets MT5 account.
**Telegram**: Create a bot via @BotFather, get chat ID from @userinfobot.
**WhatsApp**: Configure via Meta Business API dashboard.

### Step 4: Set Initial Mode

Edit `data/state.json` and set `"mode": 1` (Advisory) to start safely.

### Step 5: Start

## Dashboard

Connect any WebSocket client to `ws://localhost:3078` to receive real-time JSON payloads containing:
- Live prices and spread statistics
- HTF and intraday bias with conviction scores
- Active positions with live P&L and R:R
- Liquidity map (equal highs/lows, sweep markers)
- Macro panel (DXY, yields, news countdown)
- Performance metrics (win rate, expectancy, drawdown, Sharpe)
- Risk status (halt state, daily P&L, exposure)
- Event log (all system events)
