## Architecture & Data Flow
|
||||||
|
|
||||||
|
```
|
||||||
|
Live: WS -> Buffer -> DB -> CustomTF -> IndicatorEngine -> Brain -> Decisions
|
||||||
|
│ │
|
||||||
|
Backtest: DB (History) -> Backtester ─────────┴─────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
- **Stateless Logic**: `IndicatorEngine` and `Brain` are driver-agnostic. They read from DB
|
||||||
|
and write to DB, unaware if the trigger is live WS or backtest replay.
|
||||||
|
- **Consistency**: Indicators are computed exactly the same way for live and backtest.
|
||||||
|
- **Visualization**: Dashboard queries `indicators` and `decisions` tables directly.
|
||||||
|
Decisions contain a JSON snapshot of indicators at the moment of decision.
|
||||||
|
|
||||||
|
## Key Dataclasses
|
||||||
|
|
||||||
|
```python
|
||||||
|
@dataclass
|
||||||
|
class Candle: # Standard OHLCV
|
||||||
|
time: datetime; symbol: str; interval: str; ...
|
||||||
|
|
||||||
|
@dataclass
|
||||||
|
class Decision: # Brain output
|
||||||
|
time: datetime; symbol: str; decision_type: str; confidence: float
|
||||||
|
indicator_snapshot: Dict; # Values seen by Brain at decision time
|
||||||
|
backtest_id: Optional[str] # UUID if backtest, None if live
|
||||||
|
```
|
||||||
|
|
||||||
|
## Database Schema (TimescaleDB)
|
||||||
|
|
||||||
|
| Table | Purpose | Key Columns |
|
||||||
|
|-------|---------|-------------|
|
||||||
|
| `candles` | OHLCV data | `(time, symbol, interval)` UNIQUE |
|
||||||
|
| `indicators` | Computed values | `(time, symbol, interval, indicator_name)` UNIQUE |
|
||||||
|
| `decisions` | Buy/sell signals | `(time, symbol, interval, backtest_id)` |
|
||||||
|
| `backtest_runs` | Run metadata | `(id, strategy, config, results)` |
|
||||||
|
|
||||||
|
- `decisions` table stores `indicator_snapshot` JSONB for exact replay/audit.
|
||||||
|
- Compression enabled on all hypertables (7-day policy).
|
||||||
|
|
||||||
|
## API Endpoints (src/api/server.py)
|
||||||
|
|
||||||
|
| Method | Path | Description |
|
||||||

|
||||||
|

## Code Style Guidelines
|
## Code Style Guidelines
|
||||||
|
|
||||||
### Imports
|
- **Imports**: Stdlib, then Third-party, then Local (relative within package).
|
||||||
Group in this order, separated by blank lines:
|
- **Async**: Use `async/await` for all I/O. Use `asyncpg` pool.
|
||||||
1. Standard library (`import asyncio`, `from datetime import datetime`)
|
- **Typing**: strict type hints required. `Optional[T]`, `List[T]`.
|
||||||
2. Third-party (`import websockets`, `import asyncpg`, `from fastapi import FastAPI`)
|
- **Logging**: Use `logger = logging.getLogger(__name__)`.
|
||||||
3. Local/relative (`from .websocket_client import Candle`)
|
- **Config**: Load from `config/data_config.yaml` or env vars.
|
||||||
|
|
||||||
Use relative imports (`.module`) within the `data_collector` package.
|
|
||||||
Use absolute imports for third-party packages.
|
|
||||||
|
|
||||||
### Formatting
|
|
||||||
- Line length: 100 characters max
|
|
||||||
- Indentation: 4 spaces
|
|
||||||
- Strings: double quotes (single only to avoid escaping)
|
|
||||||
- Trailing commas in multi-line collections
|
|
||||||
- Formatter: black
|
|
||||||
|
|
||||||
### Type Hints
|
|
||||||
- Required on all function parameters and return values
|
|
||||||
- `Optional[Type]` for nullable values
|
|
||||||
- `List[Type]`, `Dict[str, Any]` from `typing` module
|
|
||||||
- `@dataclass` for data-holding classes (e.g., `Candle`, `BufferStats`)
|
|
||||||
- Callable types for callbacks: `Callable[[Candle], Awaitable[None]]`
|
|
||||||
|
|
||||||
### Naming Conventions
|
|
||||||
- Classes: `PascalCase` (DataCollector, CandleBuffer)
|
|
||||||
- Functions/variables: `snake_case` (get_candles, buffer_size)
|
|
||||||
- Constants: `UPPER_SNAKE_CASE` (DB_HOST, MAX_BUFFER_SIZE)
|
|
||||||
- Private methods: `_leading_underscore` (_handle_reconnect, _flush_loop)
|
|
||||||
|
|
||||||
### Docstrings
|
|
||||||
- Triple double quotes on all modules, classes, and public methods
|
|
||||||
- Brief one-line description on first line
|
|
||||||
- Optional blank line + detail if needed
|
|
||||||
- No Args/Returns sections (not strict Google-style)
|
|
||||||
```python
|
|
||||||
"""Add a candle to the buffer
|
|
||||||
Returns True if added, False if buffer full and candle dropped"""
|
|
||||||
```
|
|
||||||
|
|
||||||
### Error Handling
|
|
||||||
- `try/except` with specific exceptions (never bare `except:`)
|
|
||||||
- Log errors with `logger.error()` before re-raising in critical paths
|
|
||||||
- Catch `asyncio.CancelledError` to break loops cleanly
|
|
||||||
- Use `finally` blocks for cleanup (always call `self.stop()`)
|
|
||||||
- Use `@asynccontextmanager` for resource acquisition (DB connections)
|
|
||||||
|
|
||||||
### Async Patterns
|
|
||||||
- `async/await` for all I/O operations
|
|
||||||
- `asyncio.Lock()` for thread-safe buffer access
|
|
||||||
- `asyncio.Event()` for stop/flush coordination
|
|
||||||
- `asyncio.create_task()` for background loops
|
|
||||||
- `asyncio.gather(*tasks, return_exceptions=True)` for parallel cleanup
|
|
||||||
- `asyncio.wait_for(coro, timeout)` for graceful shutdown
|
|
||||||
- `asyncio.run(main())` as the entry point
|
|
||||||
|
|
||||||
### Logging
|
|
||||||
- Module-level: `logger = logging.getLogger(__name__)` in every file
|
|
||||||
- Format: `'%(asctime)s - %(name)s - %(levelname)s - %(message)s'`
|
|
||||||
- Log level from env: `getattr(logging, os.getenv('LOG_LEVEL', 'INFO'))`
|
|
||||||
- Use f-strings in log messages with relevant context
|
|
||||||
- Levels: DEBUG (candle receipt), INFO (lifecycle), WARNING (gaps), ERROR (failures)
|
|
||||||
|
|
||||||
### Database (asyncpg + TimescaleDB)
|
|
||||||
- Connection pool: `asyncpg.create_pool(min_size=1, max_size=N)`
|
|
||||||
- `@asynccontextmanager` wrapper for connection acquisition
|
|
||||||
- Batch inserts with `executemany()`
|
|
||||||
- Upserts with `ON CONFLICT ... DO UPDATE`
|
|
||||||
- Positional params: `$1, $2, ...` (not `%s`)
|
|
||||||
- Use `conn.fetch()`, `conn.fetchrow()`, `conn.fetchval()` for results
|
|
||||||
|
|
||||||
### Configuration
|
|
||||||
- Secrets via environment variables (`os.getenv('DB_PASSWORD')`)
|
|
||||||
- Non-secret config in `config/data_config.yaml`
|
|
||||||
- Constructor defaults fall back to env vars
|
|
||||||
- Never commit `.env` files (contains real credentials)
|
|
||||||
|
|
||||||
## Common Tasks
|
## Common Tasks
|
||||||
|
|
||||||
### Add New API Endpoint
|
### Add New Indicator
|
||||||
1. Add route in `src/api/server.py` with `@app.get()`/`@app.post()`
|
1. Add to `config/data_config.yaml` under `indicators`.
|
||||||
2. Type-hint query params with `Query()`; return `dict` or raise `HTTPException`
|
2. Update `IndicatorEngine._compute_indicator` in `src/data_collector/indicator_engine.py` if new type (non-SMA).
|
||||||
3. Use `asyncpg` pool for database queries
|
3. No DB schema change needed (rows are generic).
|
||||||
|
|
||||||
### Add New Data Source
|
### Run Backtest
|
||||||
1. Create module in `src/data_collector/` following `websocket_client.py` pattern
|
|
||||||
2. Implement async `connect()`, `disconnect()`, `receive()` methods
|
|
||||||
3. Use callback architecture: `on_data`, `on_error` callables
|
|
||||||
|
|
||||||
### Database Schema Changes
|
|
||||||
1. Update `docker/init-scripts/01-schema.sql`
|
|
||||||
2. Update `DatabaseManager` methods in `src/data_collector/database.py`
|
|
||||||
3. Rebuild: `docker-compose down -v && docker-compose up -d --build`
|
|
||||||
|
|
||||||
### Writing Tests
|
|
||||||
1. Create test files in `tests/data_collector/` (e.g., `test_websocket_client.py`)
|
|
||||||
2. Use `pytest-asyncio` for async tests: `@pytest.mark.asyncio`
|
|
||||||
3. Mock external services (WebSocket, database) with `unittest.mock`
|
|
||||||
4. Descriptive names: `test_websocket_reconnection_with_backoff`
|
|
||||||
|
|
||||||
### Historical Data Backfill
|
|
||||||
The `backfill.py` module downloads historical candle data from Hyperliquid's REST API.
|
|
||||||
|
|
||||||
**API Limitations:**
|
|
||||||
- Max 5000 candles per coin/interval combination
|
|
||||||
- 500 candles per response (requires pagination)
|
|
||||||
- Available intervals: 1m, 3m, 5m, 15m, 30m, 1h, 2h, 4h, 8h, 12h, 1d, 3d, 1w, 1M
|
|
||||||
|
|
||||||
**Usage - Python Module:**
|
|
||||||
```python
|
|
||||||
from data_collector.backfill import HyperliquidBackfill
|
|
||||||
from data_collector.database import DatabaseManager
|
|
||||||
|
|
||||||
async with HyperliquidBackfill(db, coin="BTC", intervals=["1m", "1h"]) as backfill:
|
|
||||||
# Backfill last 7 days for all configured intervals
|
|
||||||
results = await backfill.backfill_all_intervals(days_back=7)
|
|
||||||
|
|
||||||
# Or backfill specific interval
|
|
||||||
count = await backfill.backfill_interval("1m", days_back=3)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Usage - CLI:**
|
|
||||||
```bash
|
```bash
|
||||||
# Backfill 7 days of 1m candles for BTC
|
# CLI
|
||||||
cd src/data_collector && python -m data_collector.backfill --coin BTC --days 7 --intervals 1m
|
python -m data_collector.backtester --symbol BTC --intervals 37m --start 2025-01-01
|
||||||
|
|
||||||
# Backfill multiple intervals
|
# API
|
||||||
python -m data_collector.backfill --coin BTC --days 30 --intervals 1m 5m 1h
|
curl -X POST http://localhost:8000/api/v1/backtests \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
# Backfill MAXIMUM available data (5000 candles per interval)
|
-d '{"symbol": "BTC", "intervals": ["37m"], "start_date": "2025-01-01"}'
|
||||||
python -m data_collector.backfill --coin BTC --days max --intervals 1m 1h 1d
|
|
||||||
|
|
||||||
# Or use the convenience script
|
|
||||||
bash scripts/backfill.sh BTC 7 "1m 5m 1h"
|
|
||||||
bash scripts/backfill.sh BTC max "1m 1h 1d" # Maximum data
|
|
||||||
```
|
```
|
||||||
|
|
||||||
**Data Coverage by Interval:**
|
|
||||||
- 1m candles: ~3.5 days (5000 candles)
|
|
||||||
- 1h candles: ~7 months (5000 candles)
|
|
||||||
- 1d candles: ~13.7 years (5000 candles)

# 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:
|
||||||

```
|
||||||
|
|
||||||
|
## Step 1: Configure Synology for Remote Access
|
||||||
|
|
||||||
|
### Open PostgreSQL Port
|
||||||
|
|
||||||
|
1. **SSH into your Synology:**
|
||||||
|
```bash
|
||||||
|
ssh admin@YOUR_SYNOLOGY_IP
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Edit PostgreSQL configuration:**
|
||||||
|
```bash
|
||||||
|
# Find postgresql.conf (usually in /var/lib/postgresql/data/)
|
||||||
|
sudo vim /var/lib/postgresql/data/postgresql.conf
|
||||||
|
|
||||||
|
# Change:
|
||||||
|
# listen_addresses = 'localhost'
|
||||||
|
# To:
|
||||||
|
listen_addresses = '*'
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Edit pg_hba.conf to allow remote connections:**
|
||||||
|
```bash
|
||||||
|
sudo vim /var/lib/postgresql/data/pg_hba.conf
|
||||||
|
|
||||||
|
# Add at the end:
|
||||||
|
host all all 0.0.0.0/0 md5
|
||||||
|
# Or for specific IP:
|
||||||
|
host all all YOUR_PC_IP/32 md5
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **Restart PostgreSQL:**
|
||||||
|
```bash
|
||||||
|
sudo systemctl restart postgresql
|
||||||
|
# Or if using Docker:
|
||||||
|
cd ~/btc_bot/docker && docker-compose restart timescaledb
|
||||||
|
```
|
||||||
|
|
||||||
|
### Configure Synology Firewall
|
||||||
|
|
||||||
|
1. Open **Control Panel** → **Security** → **Firewall**
|
||||||
|
2. Click **Edit Rules**
|
||||||
|
3. Create new rule:
|
||||||
|
- **Ports:** Custom → TCP → 5433 (or your PostgreSQL port)
|
||||||
|
- **Source IP:** Your PC's IP address (or allow all)
|
||||||
|
- **Action:** Allow
|
||||||
|
4. Apply the rule
|
||||||
|
|
||||||
|
## Step 2: Test Connection
|
||||||
|
|
||||||
|
### Using psql CLI
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Replace with your Synology IP
|
||||||
|
export DB_HOST=192.168.1.100 # Your Synology IP
|
||||||
|
export DB_PORT=5433
|
||||||
|
export DB_NAME=btc_data
|
||||||
|
export DB_USER=btc_bot
|
||||||
|
export DB_PASSWORD=your_password
|
||||||
|
|
||||||
|
# Test connection
|
||||||
|
psql -h $DB_HOST -p $DB_PORT -U $DB_USER -d $DB_NAME -c "SELECT version();"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Using Python
|
||||||
|
|
||||||
|
Create `test_connection.py`:
|
||||||
|
|
||||||
|
```python
|
||||||
|
import asyncio
|
||||||
|
import asyncpg
|
||||||
|
|
||||||
|
async def test():
|
||||||
|
conn = await asyncpg.connect(
|
||||||
|
host='192.168.1.100', # Your Synology IP
|
||||||
|
port=5433,
|
||||||
|
database='btc_data',
|
||||||
|
user='btc_bot',
|
||||||
|
password='your_password'
|
||||||
|
)
|
||||||
|
|
||||||
|
version = await conn.fetchval('SELECT version()')
|
||||||
|
print(f"Connected! PostgreSQL version: {version}")
|
||||||
|
|
||||||
|
# Test candle count
|
||||||
|
count = await conn.fetchval(
|
||||||
|
"SELECT COUNT(*) FROM candles WHERE interval = '1m'"
|
||||||
|
)
|
||||||
|
print(f"Total 1m candles: {count:,}")
|
||||||
|
|
||||||
|
await conn.close()
|
||||||
|
|
||||||
|
asyncio.run(test())
|
||||||
|
```
|
||||||
|
|
||||||
|
Run it:
|
||||||
|
```bash
|
||||||
|
python test_connection.py
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 3: Export Historical 1m Data
|
||||||
|
|
||||||
|
### Option A: Using psql (Quick Export)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
psql -h $DB_HOST -p $DB_PORT -U $DB_USER -d $DB_NAME -c "
|
||||||
|
COPY (
|
||||||
|
SELECT time, symbol, interval, open, high, low, close, volume
|
||||||
|
FROM candles
|
||||||
|
WHERE symbol = 'BTC'
|
||||||
|
AND interval = '1m'
|
||||||
|
AND time >= '2025-01-01'
|
||||||
|
ORDER BY time
|
||||||
|
) TO STDOUT WITH CSV HEADER;
|
||||||
|
" > btc_1m_candles.csv
|
||||||
|
```
|
||||||
|
|
||||||
|
### Option B: Using Python (With Progress Bar)
|
||||||
|
|
||||||
|
Create `export_candles.py`:
|
||||||
|
|
||||||
|
```python
|
||||||
|

||||||
|

|
)
|

|
|

|
with tqdm(total=total, unit='candles') as pbar:
|
||||||
|
while True:
|
||||||
|
rows = await cursor.fetch(1000)
|
||||||
|
if not rows:
|
||||||
|
break
|
||||||
|
for row in rows:
|
||||||
|
writer.writerow(row)
|
||||||
|
pbar.update(len(rows))
|
||||||
|
|
||||||
|
print(f"✓ Exported to {output_file}")
|
||||||
|
print(f" Total rows: {total:,}")
|
||||||
|
|
||||||
|
finally:
|
||||||
|
await conn.close()
|
||||||
|
|
||||||
|
if __name__ == "__main__":
|

|
asyncio.run(export_candles(

```
|
||||||
|
|
||||||
|
## Step 4: Calculate Indicators on PC
|
||||||
|
|
||||||
|
### Using pandas-ta (Recommended)
|
||||||
|
|
||||||
|
Create `calculate_indicators.py`:
|
||||||
|
|
||||||
|
```python
|
||||||
|
import pandas as pd
|
||||||
|
import pandas_ta as ta
|
||||||

def calculate_indicators(input_file: str, output_file: str):
|

"""Calculate technical indicators from candle data"""
|
||||||
|
|
||||||
|
# Read candles
|
||||||
|
print(f"Reading {input_file}...")
|

|
df = pd.read_csv(input_file)
|
||||||
|
df['time'] = pd.to_datetime(df['time'])
|
||||||
|
df = df.sort_values('time')
|
||||||
|
|
||||||
|
print(f"Loaded {len(df):,} candles")
|
||||||
|
|
||||||
|
# Calculate indicators
|
||||||
|
print("Calculating indicators...")
|
||||||
|
|
||||||
|
# Moving Averages
|
||||||
|
df['ma44'] = ta.sma(df['close'], length=44)
|
||||||
|
df['ma125'] = ta.sma(df['close'], length=125)
|
||||||
|
df['ma200'] = ta.sma(df['close'], length=200)
|
||||||
|
|
||||||
|
# RSI
|
||||||
|
df['rsi'] = ta.rsi(df['close'], length=14)
|
||||||
|
|
||||||
|
# Bollinger Bands
|
||||||
|
bb = ta.bbands(df['close'], length=20, std=2)
|
||||||
|
df['bb_upper'] = bb['BBU_20_2.0']
|
||||||
|
df['bb_middle'] = bb['BBM_20_2.0']
|
||||||
|
df['bb_lower'] = bb['BBL_20_2.0']
|
||||||
|
|
||||||
|
# MACD
|
||||||
|
macd = ta.macd(df['close'], fast=12, slow=26, signal=9)
|
||||||
|
df['macd'] = macd['MACD_12_26_9']
|
||||||
|
df['macd_signal'] = macd['MACDs_12_26_9']
|
||||||
|
df['macd_histogram'] = macd['MACDh_12_26_9']
|
||||||
|
|
||||||
|
# Save
|
||||||
|
print(f"Saving to {output_file}...")
|
||||||
|
df.to_csv(output_file, index=False)
|
||||||
|
|
||||||
|
print(f"✓ Calculated {len(df.columns) - 8} indicators")
|
||||||
|
print(f" Output: {output_file}")
|
||||||
|
|
||||||
|
return df
|
||||||
|
|

|
if __name__ == "__main__":
|

|
df = calculate_indicators(
|

print(df[['time', 'close', 'ma44', 'ma125', 'rsi']].tail(10))
|
||||||
|
```
|
||||||
|
|
||||||
|
Install dependencies:
|
||||||
|
```bash
|
||||||
|
pip install pandas pandas-ta
|
||||||
|
```
|
||||||
|
|
||||||
|
Run:
|
||||||
|
```bash
|
||||||
|
python calculate_indicators.py
|
||||||
|
```
|
||||||
|
|
||||||
|
### Performance Tips
|
||||||
|
|
||||||
|
- **Chunk processing** for very large files (> 1GB):
|
||||||
|
```python
|
||||||
|
# Process 100k rows at a time
|
||||||
|
chunksize = 100000
|
||||||
|
for chunk in pd.read_csv(input_file, chunksize=chunksize):
|
||||||
|
# Calculate indicators for chunk
|
||||||
|
pass
|
||||||
|
```
|
||||||
|
|
||||||
|
- **Use multiple cores:**
|
||||||
|
```python
|
||||||
|
from multiprocessing import Pool
|
||||||
|
# Parallelize indicator calculation
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 5: Import Indicators Back to Synology
|
||||||
|
|
||||||
|
### Option A: Direct SQL Insert (Fastest)
|

Run complete workflow:

```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Connection Refused
|
||||||
|
```
|
||||||
|
Error: connection refused
|
||||||
|
```
|
||||||
|
- Check if PostgreSQL is running: `docker ps | grep timescale`
|
||||||
|
- Verify port is open: `telnet SYNOLOGY_IP 5433`
|
||||||
|
- Check firewall rules on Synology
|
||||||
|
|
||||||
|
### Permission Denied
|
||||||
|
```
|
||||||
|
Error: password authentication failed
|
||||||
|
```
|
||||||
|
- Verify password is correct
|
||||||
|
- Check pg_hba.conf has proper entries
|
||||||
|
- Restart PostgreSQL after config changes
|
||||||
|
|
||||||
|
### Slow Performance
|
||||||
|
- Use batch inserts (1000 rows at a time)
|
||||||
|
- Process large datasets in chunks
|
||||||
|
- Consider using COPY command for very large imports
|
||||||
|
- Close cursor after use
|
||||||
|
|
||||||
|
### Memory Issues
|
||||||
|
- Don't load entire table into memory
|
||||||
|
- Use server-side cursors
|
||||||
|
- Process in smaller date ranges
|
||||||
|
- Use chunksize when reading CSV
|
||||||
|
|
||||||
|
## Security Notes
|
||||||
|
|
||||||
|
⚠️ **Important:**
|
||||||
|
- Use strong password for database user
|
||||||
|
- Limit pg_hba.conf to specific IPs when possible
|
||||||
|
- Use VPN if accessing over internet
|
||||||
|
- Consider SSL connection for remote access
|
||||||
|
- Don't commit passwords to git
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
Once indicators are calculated and imported:
|
||||||
|
|
||||||
|
1. **Backtests will be fast** - Server just reads pre-calculated values
|
||||||
|
2. **Dashboard will load quickly** - No on-the-fly calculation needed
|
||||||
|
3. **Can add more indicators** - Just re-run sync with new calculations
|
||||||
|
|
||||||
|
## Alternative: SSH Tunnel (More Secure)
|
||||||
|
|
||||||
|
Instead of opening PostgreSQL port, use SSH tunnel:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# On your PC
|
||||||
|
ssh -L 5433:localhost:5433 admin@SYNOLOGY_IP
|
||||||
|
|
||||||
|
# Now connect to localhost:5433 (tunnels to Synology)
|
||||||
|
export DB_HOST=localhost
|
||||||
|
export DB_PORT=5433
|
||||||
|
python sync_indicators.py
|
||||||
|
```
|
||||||
|
|
||||||
|
This encrypts all traffic and doesn't require opening PostgreSQL port.
|
||||||
