I’m on IB. I want to buy stocks, right now! I don’t have time to wait for my money to transfer to IB. Can I buy stocks for x amount of $ now and simultanously transfer money to my account to cover the loan instantly without accruing interest? Sort of like using a credit card and paying it full ASAP.
I don’t like using loans for anything, but sometimes you’re itching to buy some stock 
I simply can’t find the information yet, so I thought I’d ask. Maybe I’m just too stupid to understand it.
