Manual Download
What It Does
The Manual Download panel lets you select IEMOP market file types and a date range, then downloads all matching files from the IEMOP public website directly to a folder on your computer. No login is required.
Data is available from 2024-08-13 onwards. Both date pickers enforce this minimum date.
File Type Selection
File types are shown as pill buttons. Click a pill to select or deselect it. The badge in the card header shows how many types are currently selected.
Select All selects every file type. Clear deselects all.

MNM is a market-reports file type with a different request shape. MNM files are extracted in full rather than as CSV only. The source ZIP archive is kept alongside the extracted files. Existing MNM CSVs are overwritten on re-download — unlike other types, where existing files are skipped.
SLD files are delivered as PDFs — one per island group (Luzon, Visayas, Mindanao) — and are saved directly to an SLD/ subfolder rather than extracted from a ZIP archive.
The capeg type saves files to a CAPEG/ subfolder (uppercase). This differs from the lowercase type ID displayed here.
Date Range
| Field | Default | Minimum | Maximum |
|---|---|---|---|
| From (start date) | 14 days before today | 2024-08-13 | Today |
| To (end date) | 7 days before today | 2024-08-13 | Today |
If To is before From, an inline error appears: "End date must be after start date".
Destination Folder
The destination folder is shown as a read-only text field. Click Browse to open a native folder picker. The chosen folder is remembered across sessions.
Files are organised into subfolders by type within the destination: RTD/, RTDOR/, DAP/, and so on. Subfolders are created automatically if they do not exist.
Start Download Button
The Start Download button is disabled until all of the following conditions are met:
- At least one file type is selected
- Start date is set
- End date is set
- Destination folder is set
- End date is on or after start date
While disabled, a hint strip below the card header explains which precondition is blocking.
During a download, the button shows "Downloading..." and is disabled.
Download Behaviour
- Sequential by file type, parallel within each type. File types are downloaded one at a time in order; within each type, up to 10 files download concurrently.
- Skip existing files. A file already present at the target path is skipped and counted in the "skipped" total — not overwritten.
- Automatic retry. Each file is retried once on failure (two total attempts), with a 1-second delay between attempts.
- ZIP extraction. Most types arrive as ZIP archives; the downloader extracts the CSVs. Some types (RTDOR, RTDOE, RTDHS, MP, RTDOPRSVSUMM, capeg) arrive as direct CSVs. SLD files arrive as direct PDFs.
- Failure report. If any files fail after all retries, a text file named
download_failures_<timestamp>.txtis written to the destination folder, listing each failure with its error message and retry count.
Activity Dock During Download
Progress messages appear in the Activity Dock in real time:
✓ filename— file downloaded successfully⊙ filename (already exists)— file skipped✗ filename - error message— file failed after retries
The dock shows "running" status while a download is in progress and "idle" when complete.
Stat Tiles
Two tiles appear after a run:
- Total Files — total count of extracted/saved files
- Failed — count of files that failed after all retries
