## Setup

### Basic Installation
```bash

```

### 🍺 Homebrew (macOS/Linux)
```bash
brew tap yahoofinancelive/yliveticker
brew install yliveticker
```

### 🖥️ Full Experience (CLI & Data Analysis)

To get the interactive dashboard and pandas support:
```bash
pip install yliveticker[cli,pandas]
```

## Usage Examples

### 1. Interactive Dashboard (CLI)
The easiest way to watch stocks. It provides a real-time, color-coded dashboard with **sparklines** and live status updates.

```bash
# Watch multiple symbols and export to CSV
yliveticker watch AAPL MSFT TSLA BTC-USD --export my_data.csv
```

**How it looks:**

╰──────────────────────────────────────────────────────────────────────────╯
```

### 2. Basic Ticker (Blocking)
This is the simplest way to print live updates to the console.

```python
import yliveticker

# this function is called on each ticker update
def on_new_msg(ws, msg):
    print(msg)

yliveticker.YLiveTicker(on_ticker=on_new_msg, ticker_names=["BTC-USD", "AAPL", "EURUSD=X"])
```

### 2. Time Series and OHLCV (Pandas)
Use `YTimeSeries` to collect data into a structured format for analysis.

```python
import yliveticker
from yliveticker import YTimeSeries

ts = YTimeSeries()

# Collect data (press Ctrl+C to stop and see results)
try:
    yliveticker.YLiveTicker(on_ticker=ts.on_ticker, ticker_names=["BTC-USD"])
except KeyboardInterrupt:
    pass

# Get raw collected data as a pandas DataFrame
df = ts.get_dataframe()
print(df.head())

# Get 1-minute OHLCV candles
ohlcv = ts.get_ohlcv(interval='1Min')
for symbol, data in ohlcv.items():
    print(f"\n--- {symbol} ---")
    print(data)
```

### 3. Time Series Database (TSDB) & Grafana
Store and visualize live ticker data using high-performance time-series databases and Grafana.

#### Installation
Install the necessary drivers for your chosen database:
```bash
# For all supported databases
pip install yliveticker[all]

# Or individually
pip install yliveticker[influxdb]
pip install yliveticker[timescaledb]
pip install yliveticker[clickhouse]
pip install yliveticker[questdb]
pip install yliveticker[timestream]
```

#### Supported Sinks
- **InfluxDB**: Native Flux support with tag/field mapping.
- **TimescaleDB**: Automated hypertable creation and bulk inserts.
- **ClickHouse**: High-throughput columnar storage.
- **QuestDB**: Ultra-fast ingestion via InfluxDB Line Protocol (ILP).
- **Amazon Timestream**: AWS-native serverless time-series database.

#### Quick Start with Docker & Grafana
We provide a pre-configured environment with InfluxDB and Grafana.

1. **Start the stack**:
   ```bash
   cd docker
   docker-compose up -d
   ```
2. **Run the example script**:
   ```bash
   python examples/tsdb_example.py
   ```
3. **Visualize**: Open `http://localhost:3000` (User: `admin`, Pass: `admin`) to see the live "Yahoo Finance Live Ticker" dashboard.

## Configuration

The `YLiveTicker` constructor accepts several parameters for fine-tuning:

| Parameter | Default | Description |
| :--- | :--- | :--- |
| `on_ticker` | `None` | Callback function `f(ws, msg)` called on each update. |
| `ticker_names` | `["AMZN"]` | List of Yahoo Finance symbols to subscribe to. |
| `reconnect` | `5` | Delay in seconds before attempting to reconnect on failure. |
| `ping_interval` | `15` | Interval in seconds to send WebSocket pings. |
| `ping_timeout` | `10` | Timeout in seconds to wait for a pong response. |
| `enable_socket_trace` | `False` | Set to `True` to see raw WebSocket frames. |

## Note on Trading Hours
If you don't observe any live metrics, please check the **trading hours** for your specific market. Many traditional stock symbols will only provide updates during market hours. Crypto symbols (like `BTC-USD`) usually stream 24/7.
