Stock MACD Strategy with Long Entries and Configurable Stops
Article Strategy library · Author: Myquant
Summary
This source describes a stock strategy that calculates MACD from adjusted daily closing prices across a configured stock universe. It opens long positions when the MACD line and signal line are positive, the MACD line is rising, and it is above the signal line. It closes an existing long when both lines are negative and the MACD line is falling below the signal line. The code also includes configurable entry confirmation, position sizing, and fixed or movement-based profit and loss exits.
The implementation relies on a configuration file, market data, adjusted-price factors, and a brokerage framework. It includes initialization logic for historical data and open positions, but the supplied excerpt is incomplete, so some exit details cannot be fully assessed. No backtest period, results, benchmark comparison, transaction costs, or evaluation of parameter choices are reported. The source is an implementation example rather than evidence that the trading rules produce an edge; execution assumptions and risk controls would need review before practical use.
Key ideas
- The strategy uses MACD line and signal line direction and position to time long entries and exits.
- It calculates indicators from adjusted daily closing prices for a configured stock universe.
- Entry confirmation, trade size, and fixed or trailing-style exit settings are configurable.
- The excerpt gives no performance results, and its truncation limits assessment of the complete implementation.
