## 📦 Installation

Install via pip:

```bash
pip install tradingview-indicators
```

### Requirements

- Python 3.11+
- fastdtw >= 0.3.4
- numpy >= 2.3.4
- pandas[performance] >= 2.3.3
- pytest >= 8.4.2

## 🚀 Quick Start

```python
import pandas as pd
import tradingview_indicators as ta

# Load your market data
df = pd.read_csv("BTCUSDT_1d_spot.csv")
source = df["close"]

# Calculate indicators
df["EMA_14"] = ta.ema(source, 14)
df["RSI_14"] = ta.RSI(source, 14)

# MACD with histogram
macd = ta.MACD(source, 12, 26, 9)
df["MACD_Histogram"] = macd.get_histogram

# Directional Movement Index
dmi = ta.DMI(df, "close")
df["ADX"] = dmi.adx()[0]
df["DI_Plus"] = dmi.adx()[1]
df["DI_Minus"] = dmi.adx()[2]

# Bollinger Bands
bb = ta.bollinger_bands(source, 20, 2)
df["BB_Upper"] = bb[0]
df["BB_Middle"] = bb[1]
df["BB_Lower"] = bb[2]
```
