The most feared words on any stock exchange are margin call. A margin call is made when a position is losing money and more money is required by the broker to keep the trade open. If and when a stock ticker moves quickly, there can be people whose borrowing levels literally bankrupt them as things get worse ... fast. Volatility can be either a blessing or a curse, but if you have too much leverage, it can break a trader.
Trading platforms are portals through which users access and manage their trading accounts for their financial markets. This helps the users maintain their accounts. Generally, such platforms are offered by brokers in exchange of some fee or discounts on trade commissions. With the advent of the discount broking industry, several platforms are also available for free or rather, access to platforms is included in the brokerage you pay. These platforms can be used to conduct research, keep a track of various financial products you wish to trade in, place orders, store your past trade details as well as to authenticate users. Trading platforms have opened up the possibility of e-trading or online trading.
