Menghitung RSI

Perhitungan RSI mengikuti rumus yang sederhana. RS, atau Relative Strength, adalah rata-rata kenaikan harga dalam n periode tertentu, dibagi dengan rata-rata penurunan harga selama n periode tersebut.

\( RSI = 100 - 100/(1+RS)\)

Dengan keterangan: RS = rata-rata kenaikan harga / rata-rata penurunan harga

Semua perhitungan ini dapat dilakukan di Python hanya dengan satu baris kode. Pada latihan ini, Anda akan melakukan perhitungan RSI pertama menggunakan data harga harian historis saham Google.

Data harga harian telah dimuat sebagai stock_data. Selain itu, talib telah diimpor untuk Anda.

Petunjuk latihan

Hitung RSI menggunakan metode yang sesuai dari talib dan kolom Close pada data harga. Simpan pada kolom baru bernama RSI_14.
Hitung RSI dengan periode waktu 21 dan simpan pada kolom baru bernama RSI_21.
Cetak lima baris terakhir dari stock_data.

Latihan interaktif praktis

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

# Calculate RSI with the default time period
stock_data['RSI_14'] = ____(stock_data['____'])

# Calculate RSI with a time period of 21
stock_data['RSI_21'] = ____

# Print the last five rows
print(stock_data.____())

You’re now ready to construct signals and use them to build trading strategies. You’ll get to know the two main styles of trading strategies: trend following and mean reversion. Working with real-life stock data, you’ll gain hands-on experience in implementing and backtesting these strategies and become more familiar with the concepts of strategy optimization and benchmarking.

Exercise 1: Trading signals Exercise 2: Understand trading signals Exercise 3: Build an SMA-based signal strategy Exercise 4: Build an EMA-based signal strategy Exercise 5: Trend-following strategies Exercise 6: Construct an EMA crossover signal Exercise 7: Build and backtest a trend-following strategy Exercise 8: Mean reversion strategy Exercise 9: Match the signals with the strategies Exercise 10: Construct an RSI based signal Exercise 11: Build and backtest a mean reversion strategy Exercise 12: Strategy optimization and benchmarking Exercise 13: Conduct a strategy optimization Exercise 14: Perform a strategy benchmarking

How is your trading strategy performing? Now it’s time to take a look at the detailed statistics of the strategy backtest result. You’ll gain knowledge of useful performance metrics, such as returns, drawdowns, Calmar ratio, Sharpe ratio, and Sortino ratio. You’ll then tie it all together by learning how to obtain these ratios from the backtest results and evaluate the strategy performance on a risk-adjusted basis.

Exercise 1: Strategy return analysis Exercise 2: Review return results of a backtest Exercise 3: Plot return histograms of a backtest Exercise 4: Compare return results of multiple strategies Exercise 5: Drawdown Exercise 6: Review performance with drawdowns Exercise 7: Calculate and review the Calmar ratio Exercise 8: Sharpe ratio and Sortino ratio Exercise 9: Evaluate strategy performance by Sharpe ratio Exercise 10: Evaluate strategy performance by Sortino ratio Exercise 11: Congratulations!
