Available Margin to Trade consists of your Funds balance & margin against eligible holdings.

You can increase your Available Margin to Trade by adding Funds or by creating a Margin Pledge against your eligible holdings in Accounts -> Stock Pledging.

Peak Margin is the minimum margin that must be collected by brokers from their clients in advance of placing any intraday / delivery order.

Peak Margin shortfall occurs when you buy a share from 80% margin released against delivery sell transactions and such sell position is subsequently bought back.
You will be charged a penalty if margin shortfall is due to insufficient margin.

You can check your available cash and margin by visiting Account → Trading balance screen on web or mobile app. Here you will see the Cash balance and the margins from pledge holdings
