Definition
Trading is the process of buying and selling securities. The procedure of trading consists of two processes, i.e. Delivery (when securities are sold) and Receipt (when securities are purchased). These two processes can be understood as follows:

I. Process of Receipt Note: One can also give "Standing Instruction" to receive credits into the account directly without having to give the receipt instruction to the broker every time.

II. Process of Delivery Note: This instruction should reach the DP's office at least 24 hours before the pay-in. Failure in doing so transfers the entire risk upon the investor.
