+# BTC Accumulation Bot - Implementation Summary
+
+## Current Status: ✅ CORE SYSTEM COMPLETE
+
+### What We've Built
+
+This is a **production-ready cryptocurrency trading data collection and backtesting system** for cbBTC on Hyperliquid exchange.
+
+---
+
+## Architecture Overview
+
+```
+Live Data Flow:
+Hyperliquid WS → WebSocket Client → Candle Buffer → TimescaleDB 
+                                                        ↓
+Custom TF Generator → Indicator Engine (MA44, MA125) → Brain → Decisions
+                                                        ↓
+Backtest Flow:
+Historical DB Data → Backtester → Same Indicator Engine/Brain → Simulated Trades
+```
+
+---
+
+## Core Components (All Implemented)
+
+### 1. Data Collection Pipeline
+
+**WebSocket Client** (`websocket_client.py`)
+- Connects to Hyperliquid WebSocket API
+- Automatic reconnection with exponential backoff (1s to 15min)
+- Handles multiple candle formats
+- Health monitoring and connection metrics
+
+**Candle Buffer** (`candle_buffer.py`)
+- Thread-safe circular buffer (1000 max size)
+- Async batch flushing (30s interval or 100 candles)
+- Gap detection in candle sequences
+- Statistics tracking for monitoring
+
+**Database Manager** (`database.py`)
+- asyncpg connection pool (min: 2, max: 20)
+- Batch inserts with conflict resolution
+- Gap detection using window functions
+- Health statistics queries
+
+### 2. Data Processing
+
+**Custom Timeframe Generator** (`custom_timeframe_generator.py`)
+- Standard intervals: 3m, 5m, 15m, 30m, 1h, 2h, 4h, 8h, 12h, 1d, 3d, 1w, 1M
+- Custom intervals: **37m**, **148m** (Fibonacci-based)
+- Real-time aggregation from 1m candles
+- Historical backfill capability
+- Integrity verification
+
+**Indicator Engine** (`indicator_engine.py`)
+- Stateless design (same code for live and backtest)
+- Configurable indicators via dataclasses
+- Currently implemented: **SMA (Simple Moving Average)**
+- Indicators configured:
+  - MA44 (44-period SMA) on 37m, 148m, 1d
+  - MA125 (125-period SMA) on 37m, 148m, 1d
+- Batch computation for historical data
+
+### 3. Decision Making
+
+**Brain** (`brain.py`)
+- Strategy-based evaluation system
+- Pluggable strategy loader
+- Decision logging with full indicator snapshots (JSONB)
+- Supports live trading and backtesting
+- Current strategies:
+  - MA44Strategy: Long when Price > MA44, Short when Price < MA44
+  - MA125Strategy: Long when Price > MA125, Short when Price < MA125
+
+**Strategy System** (`strategies/`)
+- Base class with abstract interface
+- Signal types: OPEN_LONG, OPEN_SHORT, CLOSE_LONG, CLOSE_SHORT, HOLD
+- Confidence scoring (0.0 - 1.0)
+- Position-aware decision making
+
+### 4. Backtesting & Simulation
+
+**Simulator** (`simulator.py`)
+- Account management with leverage support
+- Trade tracking with P&L calculation
+- Fee calculation (maker/taker)
+- Equity mark-to-market updates
+- Statistics generation (win rate, total P&L, etc.)
+
+**Backtester** (`backtester.py`)
+- Historical replay through same IndicatorEngine/Brain
+- UUID-based run tracking
+- Progress logging
+- Results storage in database
+- CLI interface for running backtests
+
+### 5. API & Dashboard
+
+**FastAPI Server** (`api/server.py`)
+Endpoints:
+- `GET /` - API status
+- `GET /api/v1/candles` - Query candle data
+- `GET /api/v1/candles/latest` - Latest candle

+- `GET /dashboard` - Static dashboard
+
+**Dashboard**
+- Real-time web interface
+- Connects to API endpoints
+- Visualizes candles, indicators, and decisions
+
+---
+
+## Database Schema (TimescaleDB)
+
+### Tables
+
+**candles** - OHLCV data
+- `(time, symbol, interval)` UNIQUE
+- Compression enabled (7-day policy)

+- Stores indicator_snapshot (JSONB) for audit
+- Distinguishes live vs backtest decisions
+
+**backtest_runs** - Backtest metadata
+- `(id, strategy, config, results)`
+- JSON config and results storage
+
+**data_quality** - Quality issues log
