Menghitung ADX

Average Directional Movement Index (ADX) dikembangkan oleh J. Welles Wilder sebagai indikator kekuatan tren. Indikator ini menggabungkan dua indikator lain, yaitu plus directional index (+DI) dan minus directional indicator (-DI), dan diperoleh melalui perhitungan yang cukup panjang. Namun, dengan Python, Anda dapat menghitungnya hanya dengan satu baris kode. Pada latihan ini, Anda akan mengimplementasikan indikator ADX pertama Anda menggunakan data harga harian saham Tesla.

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

Petunjuk latihan

Hitung ADX menggunakan fungsi yang sesuai dari talib, serta kolom High, Low, dan Close pada stock_data. Simpan hasilnya pada kolom baru ADX_14.
Hitung ADX lagi. Kali ini ubah periode default menjadi 21, dan simpan pada kolom baru ADX_21.
Cetak lima baris terakhir dari stock_data.

Latihan interaktif praktis

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

# Calculate the ADX with the default time period
stock_data['ADX_14'] = ____(stock_data['____'],
                            stock_data['____'], 
                            stock_data['____'])

# Calculate the ADX with the time period set to 21
stock_data['ADX_21'] = ____

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

Let's dive into the world of technical indicators—a useful tool for constructing trading signals and building strategies. You’ll get familiar with the three main indicator groups, including moving averages, ADX, RSI, and Bollinger Bands. By the end of this chapter, you’ll be able to calculate, plot, and understand the implications of indicators in Python.

Exercise 1: MA sebagai indikator tren Exercise 2: Hitung dan plot dua EMA Exercise 3: SMA vs. EMA Exercise 4: Indikator kekuatan: ADX Exercise 5: Memahami ADX Exercise 6: Menghitung ADX

Exercise 7: Visualisasikan ADX Exercise 8: Indikator momentum: RSI Exercise 9: Memahami RSI Exercise 10: Menghitung RSI Exercise 11: Visualisasikan RSI Exercise 12: Indikator volatilitas: Bollinger Bands Exercise 13: Memahami Bollinger Bands Exercise 14: Mengimplementasikan Bollinger Bands

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!
