The DefaultStrategy is a trading strategy that performs backtesting using various technical analysis (TA) indicators. The strategy consists of three main functions: populate_indicators, populate_buy_trend, and populate_sell_trend. The populate_indicators function calculates and adds several TA indicators to the input DataFrame.
These indicators include ADX, Awesome Oscillator, MACD, MFI, Minus Directional Movement (-DM), Plus Directional Movement (+DM), RSI, Fisher RSI, Stochastic Oscillator (Slow %K and Slow %D), Bollinger Bands, Exponential Moving Averages (EMA), SAR, Simple Moving Average (SMA), Triple Exponential Moving Average (TEMA), Hilbert Transform - Sine Wave, and Heikin-Ashi candles.
By adding these indicators, the DataFrame is enriched with valuable information for strategy analysis.
The populate_buy_trend function determines the buy signal based on the TA indicators. In this strategy, a buy signal is generated if the RSI and Stochastic %D are below 35, ADX is above 30, and Plus Directional Indicator (+DI) is above 0.5. Additionally, a buy signal is triggered if ADX is above 65 and +DI is above 0.5. When these conditions are met, the 'buy' column of the DataFrame is set to 1. The populate_sell_trend function determines the sell signal based on the TA indicators. A sell signal is generated if the RSI or Stochastic %D cross above 70, ADX is above 10, and Minus Directional Indicator (-DI) is above 0. Additionally, a sell signal is triggered if ADX is above 70 and -DI is above 0.5. When these conditions are met, the DataFrame is not modified, implying a sell signal is not generated explicitly. By combining the calculations of indicators, buy signals, and sell signals, the DefaultStrategy aims to provide a basis for backtesting different trading strategies on the website.
