Downloading One Timeframe of History for All Market Watch Symbols
Summary
This utility downloads historical quote data for a selected timeframe across every symbol in the platform’s Market Watch. Its purpose is to make data available for backtesting across multiple instruments while keeping the timeframe consistent. It can also help prevent indicator or expert errors that arise when a chart lacks enough historical bars for its calculations, and it supports work on symbols other than the active chart’s symbol.
The workflow is to launch the script, select the timeframe, and let it retrieve data for the listed symbols. The document says downloaded history is written to disk when the terminal is later restarted. It gives no benchmark or evidence about download speed, history completeness, or compatibility limits. Users should therefore treat it as a history preparation aid and verify that the available data covers the period their analysis requires.
Key ideas
- The script retrieves historical quotes for all symbols in Market Watch at one selected timeframe.
- The downloaded history can support broader single-timeframe backtesting.
- Having sufficient history may prevent calculation errors in indicators and expert systems.
- The document says history is flushed to disk after the terminal is restarted.
