Hi guys, completely new to the site, but traded Options in the 90s for a while and trying to get back into it now on my IG demo account. Please bear with me for stupid newbie question! If I decide I want to sell Puts, which are in theory limitless with their potential loss, does the account automatically trade you out of the position if you reach the margin? or is this manual and you could end up with a negative account value that you have to then repay?
Thanks guys
