What Is a Margin Call? Definition https://www.investopedia.com/terms/m/margincall.asp A margin call occurs when the value of an investor's margin account (that is, one that contains securities bought with borrowed money) falls below the broker's required amount. A margin call is the broker's demand that an investor deposit additional money or securities so that the account is brought up to the minimum value, known as the maintenance margin.
A margin call usually means that one or more of the securities held in the margin account has decreased in value below a certain point. The investor must either deposit more money in the account or sell some of the assets held in the account.
Your account must have a minimum balance you have to keep in it.
