Your PC may have been forcefully shut down or you may have closed the console running the Superalgos backend while running a data-mining operation. Such situations may cause some data to become corrupt.
1. Check the integrity of the sensor bot data
Go to the
Exchange-Raw-Data folder under
Data-Storage > Exchange > Market > Masters and keep opening the subfolders to get to the last day available, and open the
Data.json file. If the file opens fine, this may mean that the data you downloaded from the exchange is safe.
If the last file in
Exchange-Raw-Data does not open properly then delete the whole
Data-Storage > Exchange > Market and run the data mining operation. This will have the OHLCV sensor bot download all the data from the exchange again, and all indicators calculated from scratch.
If the sensor data seems fine, then proceed with the next step.
2. Check the integrity of indicator’s data
If you are having issues with candles you need to check the data of the Candles Volumes indicator of the Masters Data Mine located deep in
Multi-Period-Market folders under
Data-Storage > Exchange > Market > Masters > Candles-Volumes > Output > Candles.
If you find any
.tmp files or you can’t open some of the latest
Data.json files in a regular text editor, or some files are empty, chances are the files have been corrupted.
If that is the case, then you will delete the folder for each data mine within
Data-Storage > Exchange > Market, but will leave
Exchange-Raw-Data intact, and get the data mining operation running afterward. This will regenerate all indicators data products, including Candles Volumes.
3. Remember that there is a proper way to close the system!
Click to learn how to safely close superalgos
|In brief: The correct way to close Superalgos is to stop all tasks in the data-mining and trading operations, wait a few seconds until the tasks stop, and only then close the browser. Before closing the console, you must wait around a minute until there is no further activity.|
The backend application runs independently from the frontend browser-based application. You may close the browser at any point without affecting your data-mining operation or the bots you may be running in your testing or prodution environments. Once you restart the browser and navigate to the correct URL, the frontend app reconnects with the backend and you regain control over the whole operation.
1. Close all data-mining tasks. Select Stop All Exchange Tasks on the data mining node menu.
3. Wait a few seconds until all tasks are stopped and close the browser.
4. Wait for about one minute until all activity stops in the console, then close it.
