👉 Discover advanced trading strategies

Relative Strength Index (RSI)

rsi14 = ta.rsi(df['close'], length=14)

Bollinger Bands

upper, middle, lower = ta.bbands(df['close'], length=20)

MACD

macd, signal, hist = ta.macd(df['close'])

Signal Generation & Strategies

1. Crossover Signals

sma_cross = ta.crossover(df['close'], sma20)

2. Overbought/Oversold Detection

rsi_overbought = ta.overbought(rsi14, threshold=70)
rsi_oversold = ta.oversold(rsi14, threshold=30)

3. Strategy Implementation

Hold Strategy

sma_strategy = ta.hold(df['close'], sma_cross)

Oscillation Strategy

rsi_strategy = ta.oscillate(df['close'], rsi_overbought, rsi_oversold)

👉 Optimize your trading performance

Practical Example

Step-by-Step Analysis

Data Import
```
df = pd.read_csv('stock_prices.csv')
```

Indicator Calculation

sma20 = ta.sma(df['close'], 20)
rsi14 = ta.rsi(df['close'], 14)

Strategy Execution

sma_strategy_returns = sma_strategy.sum()
rsi_strategy_returns = rsi_strategy.sum()
