Hello, I'm Igor and I'm a software development engineer from Vancouver, BC.
If you came to this page to use MOEX open interest analyzer, I'm sorry but it's not available anymore and there's no plan to support it. The sourcecode for backend is available on the github page, so feel free to use it.
After many years of being in production, the site is in development mode once again, so almost nothing is here. Please bare with it!
