Which description are you referring to that doesn't list Stex as a supported exchange? Stex is listed in the ReadMe along with the rest of the supported exchanges. Maybe double-check and make sure that you are looking at the correct github page:
https://github.com/team-exor/eiquidusOk. I've managed to get the Stex synced. You were right.
The issue is now that the top boxes for Price and Marketcap shows zero values, despite market exchange is synced.
Probably because whatever I tried (reset mongo db, reindex, etc.) I was unable to manage to make "total coin supply" work.
Also, the Crontab is doing nothing when filled in with these:
*/1 * * * * /path/to/explorer/scripts/sync.sh /path/to/nodejs update > /dev/null 2>&1
*/2 * * * * /path/to/explorer/scripts/sync.sh /path/to/nodejs market > /dev/null 2>&1
*/5 * * * * /path/to/explorer/scripts/sync.sh /path/to/nodejs peers > /dev/null 2>&1
They do work though if I run them individually in terminal.
To get the Price and Marketcap boxes to show proper values you must successfully run the market sync and update sync scripts at least once each for those values to be populated.
If your crontab is not firing properly, you must have some kind of problem with your crontab syntax. I would recommend manually running each command one at a time outside of crontab to make sure you have the proper syntax and then add it into your crontab when you can verify and see that it is working without errors. I know you said you already did that but the fact that you are having problems showing the Price and Marketcap tells me that something didn't work correctly and you should pay attention to the error msgs to try and pinpoint the issue.
If you still can't figure it out, you can post some of the output from manually running the sync commands and I'll see if I can help you track down the cause of the errors.
