There are a few reasons why you may be having issues finding candles on the charts. Please, consider the following…
Check the Progress of the Data Mining Operation
If you are just getting started with Superalgos, still following the getting started guide, bear in mind it takes time for data to be downloaded from the exchange. Depending on the power of your hardware and the speed of your internet connection, it may take anything from half an hour to several hours to see the first few candles, particularly those of the Binance exchange, as the market spans back to September 2017.
Check the data mining operation on the network hierarchy. You will be able to see candles on the screen only after the OCHLV Sensor Bot and the Candles Volumes indicator in the Masters task manager of the corresponding exchange tasks node and market have both reached 100% progress.

Check the Time, Rate and Time Frame Scales
It may happen that you attempted to manipulate the charts and something went wrong in the process.
Try setting the time frame scale to 24 hours, and both the time scale and rate scale to automatic mode. Setting the time scale to automatic mode brings the whole span of the market in focus on the chart. Setting the rate scale to automatic mode sets the scale to fit the entire range of prices in the market. The goal is to make sure that all scales are set in a way in which—if there is any data to show—it will show.
If you don’t know how to do that, please watch the third video in the video tutorial series as a refresher, or use the below links to read about the time and rate scales.

Controlling the Time Scale from the Charts
1. To change the automatic scale settings, place the mouse pointer over the corresponding time box, press the Shift key and slowly scroll the wheel of the mouse. The action cycles through different possible scale automation settings. Notice a tiny green triangle to the sides of the time scale icon.
A triangle pointing right means that the maximum value of the scale is automatic.
A triangle pointing left means that the minimum value of the scale is automatic.
Both triangles present at the same time means that both minimum and maximum values are automatic.
No triangle means that both minimum and maximum values are in manual mode.
2. To adjust the scale, make sure either or both minimum and maximum values are in manual mode. Place the mouse pointer over the time box and scroll the wheel of the mouse. The scale will increase or decrease accordingly, depending on which values are set to manual.
Notice that, while changing the scale, a number is displayed replacing the actual datetime. This is a reference value of the scale, that may serve for comparison purposes, with scales in other charts.

Controlling the Time Frame Scale from the Charts
1. To set a time frame value, place the mouse pointer over the corresponding time machine or timeline chart time frame box and scroll the mouse wheel.
Check the Integrity of the Data
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.
If you are technical enough, you may want to review the latest files in 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 such is the case, this is what you need to do: 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 donwloaded from the exchange is safe.
If that is the case, then you will delete every folder within
Data-Storage > Exchange > Market > Masters but
Exchange-Raw-Data and get the data mining operation running afterwards. This will regenerate all indicators data products, including Candles Volumes.
It the last file in
Exchange-Raw-Data does not open properly then delete the whole
Data-Storage > Exchange > Market > Masters and run the data mining operation. This will have the OCHLV sensor bot download all the data from the exchange again to later be processed by the indicator bots.
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.
Check for Errors at the Browser Level
Open Chrome’s DevTools with the F12 key (when the browser is in focus) and click the Console tab, then go back and reproduce the issue trying to show the candles on the chart. The console may display errors that are not important. Pay attention if you find errors that refer to files that can not be loaded, or similar issues.
If nothing else has worked for you, then record a quick WEBM video of the problem in the charts and ask for help in the Community Telegram, thoughtfully describing the issue you are experiencing and what you have done to troubleshoot it.
Click to learn about screen capture and sharings
Hit Ctrl + F8 to capture a static PNG image.
Hit Ctrl + F9 to start capturing a GIF video, and hit the same key combination again to end the capture. Once the capture ends, it takes some time to process the capture and generate the final file.
Hit Ctrl + F10 to start capturing a WEBM video, and hit the same key combination again to end the capture. WEBM videos are processed instantly.
In all three cases, the browser downloads the resulting file and makes it available in the downloads folder.
