Hi all, I have just started out learning and have put a light amount of money onto my account to put my research into play, however earlier as I was viewing the FB drop, and I hit the buy button with the price at 273 (by accident on app), however I have only deposit Ā£50 into my account, to my surprise it said I had obtained the stock at 273. I was under the assumption that I can only buy worth of what I deposit - have I missed something?
