Buying Power

[Henrique Goldmann 2]

I recently opened my account with IBKR and DAS. I currently have 100K of BP, but I noticed that I could not use all my buying power in a few stocks. For example, when AMC was trading at $30, I could only purchase 1,000 shares, using only 30,000 from the buying power I had available. This is confusing to me because I didn't have any restrictions in the simulator when using my full Buying power.  Am I missing something? why do i suddenly have this restriction 

 

Thank you

Different stocks have different margin requirements to enter the trade. In das click on the S in the montage and it will show you shorts available as well as margin % required for long and short entries. On AMC, due to the volatility, it is on the higher end. On typical stocks it is 25%... on AMC it's anywhere from 100% to 300%.
