A margin call must be satisfied immediately and without any delay. Although some brokers may give you two to five days to meet the margin call, the fine print of a standard margin account agreement will generally state that to satisfy an outstanding margin call, the broker has the right to liquidate any or all securities or other assets held in the margin account at its discretion and without prior notice to the trader. To prevent such forced liquidation, it is best to meet a margin call and rectify the margin deficiency promptly.
