Stock Trading Panic!

Just started my journey in the world of Stock trading, Friday 4PM my application has been approved. Early Saturday I went to the platform to start buying stocks after reviewing some of it -- little do I know the MARKET is CLOSED on SATURDAY, I created a ticket to the platform, On why I cannot BUY using the APP I thought I was SCAMMED! for a while, then realizing this not Cry to-trading. I closed the ticket myself.
