You can view the margin requirements of a stock on its tear sheet in the ‘Margin requirements’ section.
Keep in mind that both the initial and maintenance margin requirements of a stock can change. If the maintenance requirement of a stock you have purchased on margin increases, it can cause a margin call in your account.
NOTE: Margin must be enabled in order to see the margin requirements on the tear sheet.
