Short answer

iRage sends margin call SMS and email when the margin utilisation exceeds the available balance.

If the margin call is received before market hours, please add the funds immediately to the Arrow account.

If the margin call is received after market hours, the funds need to be added before 11:59 PM on the same day.

Your positions will be squared off at the discretion of iRage if you don’t add the required funds within the specified time.
