Taxation of shares in a foreign stock market

Hoi! I've gotten my residency recently and I'm wondering on how taxation would work on my shares. They're in a foreign stock market, and dealt with through a foreign bank account, created before my relocation. All the information I could reach is talking about dealing through a Swiss bank account so I'm not sure what to do. Thanks!

Further info, I am currently unemployed in Switzerland or elsewhere. I am using my foreign credit card for everyday expenses, it's from the same bank as the shares and paid from that account. Relocated through family reunion, spouse is a Swiss farmer.
