The continuation of the MQL5 series focuses on reading pre-saved candle data into an MQL5 program for utilization in indicators and Expert Advisors (EAs). With the data stored in a structured file, the process involves opening the file, extracting candle values, and organizing the information for use in indicators or EAs. This section emphasizes the seamless transfer of data from external sources into MQL5, enabling users to visualize candle data.

Building an indicator to visualize this data involves setting indicator properties, determining the display format on charts, deciding the required buffers, and defining display rules for candles.
