## What it does

The skill instructs the agent how to use the `pandas-ta` library via the `df.ta` namespace. It provides ready code patterns for trend, momentum, volatility, and volume indicators such as RSI, MACD, SuperTrend, and Bollinger Bands. The agent also learns to batch indicator calculations using the `ta.Strategy` class.

Executing the code requires Python with `pandas-ta`, `pandas`, and `httpx`. The input OHLCV DataFrame demands lowercase column names: `open`, `high`, `low`, `close`, and `volume`. If column headers use uppercase like `Close`, calculations fail immediately. Time-dependent indicators like VWAP require a `DatetimeIndex`.

The guidance directly handles continuous 24/7 crypto markets. Because crypto swings hard, the skill suggests widening Bollinger Bands standard deviation to 2.5–3x and increasing the SuperTrend multiplier to 3–4x. On low-cap tokens with thin order books, volume indicators like OBV or CMF are unreliable; the skill flags this risk.

## When to use it
- calculate technical indicators on OHLCV market DataFrames
- run multi-indicator setups using ta.Strategy
- clean cryptocurrency candlestick data with forward-fill and dropna
- tune indicator parameters for crypto volatility

## Example prompts
- Calculate RSI(14) and Bollinger Bands for this hourly candle DataFrame using pandas-ta
- Create a ta.Strategy with EMA crossover and SuperTrend for crypto swing trading
- Format this raw OHLCV data with DatetimeIndex and compute VWAP

# pandas-ta — Technical Analysis for Crypto Markets

pandas-ta is a Python library that extends pandas DataFrames with 130+ technical analysis indicators accessible via `df.ta`. It covers trend, momentum, volatility, volume, and overlap indicator categories — all callable with a single method on any OHLCV DataFrame.

## Installation

```bash
uv pip install pandas-ta pandas httpx
```

## Quick Start

```python
import pandas as pd
import pandas_ta as ta

# Assume df is a DataFrame with columns: open, high, low, close, volume
# All lowercase column names required

# Single indicator
df["rsi"] = df.ta.rsi(length=14)
df["atr"] = df.ta.atr(length=14)

# Multiple indicators via strategy
df.ta.strategy(ta.Strategy(
    name="Quick Check",
    ta=[
        {"kind": "rsi", "length": 14},
        {"kind": "macd", "fast": 12, "slow": 26, "signal": 9},
        {"kind": "bbands", "length": 20, "std": 2.0},
    ]
))
```

## OHLCV DataFrame Format

pandas-ta expects a DataFrame with lowercase column names:

```python
import pandas as pd

df = pd.DataFrame({
    "open": [...],
    "high": [...],
    "low": [...],
    "close": [...],
    "volume": [...]
}, index=pd.DatetimeIndex([...]))
```

**Important**: Set the index to a `DatetimeIndex` for time-aware indicators like VWAP. Column names must be lowercase (`close`, not `Close`).

### Handling Missing Data

```python
# Drop rows with NaN in OHLCV columns
df = df.dropna(subset=["open", "high", "low", "close", "volume"])

# Forward-fill small gaps (1-2 bars max)
df = df.ffill(limit=2)

# Verify no zero-volume bars for volume indicators
df = df[df["volume"] > 0]
```

## Core Indicator Categories

### Trend Indicators

Identify market direction and trend strength.

| Indicator | Call | Key Signal |
|-----------|------|------------|
| SMA | `df.ta.sma(length=20)` | Price above = bullish |
| EMA | `df.ta.ema(length=20)` | Faster than SMA, less lag |
| SuperTrend | `df.ta.supertrend(length=10, multiplier=3)` | Direction column: 1=bull, -1=bear |
| Ichimoku | `df.ta.ichimoku()` | Returns tuple of (span, lines) DataFrames |
| VWMA | `df.ta.vwma(length=20)` | Volume-weighted price trend |
| HMA | `df.ta.hma(length=20)` | Minimal lag, smooth trend |
| ADX | `df.ta.adx(length=14)` | >25 = trending, <20 = ranging |

### Momentum Indicators

Measure speed and magnitude of price changes.

| Indicator | Call | Key Signal |
|-----------|------|------------|
| RSI | `df.ta.rsi(length=14)` | >70 overbought, <30 oversold |
| MACD | `df.ta.macd(fast=12, slow=26, signal=9)` | Histogram crossover = entry |
| Stochastic | `df.ta.stoch(k=14, d=3, smooth_k=3)` | >80 overbought, <20 oversold |
