## Script Usage

Script-mode skill — read this file, then invoke from a `bash` block:

```bash

python3 - <<'EOF'

import sys, json

sys.path.insert(0, "/data/workspace/skills/taapi")

from exports import indicator, support_resistance

# RSI on BTC/USDT 1h

rsi = indicator(name="rsi", symbol="BTC/USDT", interval="1h", exchange="binance")

print(json.dumps(rsi, indent=2))

# Support/resistance on BTC/USDT daily

sr = support_resistance(symbol="BTC/USDT", interval="1d", exchange="binance")

print(json.dumps(sr, indent=2))

EOF

```

Available functions in `exports.py`: `indicator`, `support_resistance`.

Read `exports.py` directly for exact signatures.

# TaAPI

TaAPI provides technical analysis indicators including RSI, MACD, Bollinger Bands, support/resistance, and 200+ pre-calculated indicators. No local computation needed.

## Function Reference (signatures)

All functions are in `exports.py`. `exchange` defaults to `binance`.

`symbol` uses slash format like `BTC/USDT`. `interval` accepts `1m` /

`5m` / `15m` / `30m` / `1h` / `2h` / `4h` / `1d` / `1w`.

| Function | Description |

|---|---|

| `indicator(name, symbol, interval, exchange='binance', backtrack=0, backtracks=None)` | Get a technical indicator. `name` = `rsi` / `macd` / `bbands` / `ema` / `sma` / `adx` / `stoch` / `atr` / `vwap` / etc (200+ supported). Returns dict like `{value: 67.78}` for single-output indicators or `{macd, signal, histogram}` for multi-output. |

| `support_resistance(symbol, interval, exchange='binance', indicator_type='pivots')` | Compute support/resistance levels. `indicator_type` = `pivots` / `fibonacciretracement` / `donchianchannels` / etc. |

`backtrack` returns a single historical bar N candles back.

`backtracks` (int) returns an array of the last N candles.

## Interpretation Guides

### Common Indicator Reads

| Indicator | Bullish | Bearish |

|-----------|---------|---------|

| RSI | < 30 (oversold) | > 70 (overbought) |

| MACD | Histogram crossing above zero | Histogram crossing below zero |

| Bollinger Bands | Price touching lower band | Price touching upper band |

| ADX | > 25 with +DI > -DI | > 25 with -DI > +DI |

| Stochastic | < 20 (oversold) | > 80 (overbought) |

### RSI Levels

- **> 70**: Overbought (potential reversal down)

- **50-70**: Bullish momentum

- **30-50**: Bearish momentum

- **< 30**: Oversold (potential reversal up)

### MACD Signals

- **Histogram > 0**: Bullish

- **Histogram < 0**: Bearish

- **Histogram crossing zero**: Trend change

- **MACD line crossing signal line**: Buy/sell signal

### Bollinger Bands

- **Price at upper band**: Overbought

- **Price at lower band**: Oversold

- **Bands widening**: Increasing volatility

- **Bands narrowing**: Decreasing volatility (squeeze)

## Analysis Patterns

**Trend confirmation**: Use ADX + EMA/SMA. ADX > 25 indicates strong trend. EMA crossing SMA confirms direction.

**Overbought/Oversold**: Use RSI + Stochastic together. Both confirming increases signal strength.

**Divergence**: Price making new highs/lows but indicator not confirming = potential reversal.
