"...It has been gathered that there have been growing instances of placing unauthorised orders, on behalf of clients...The trading members are hereby advised to exercise extra caution and due-diligence at their end while executing trades on behalf of their clients," BSE told the brokers.
The warning is part of an advisory on the process to be followed by trading members for withholding payout of funds and securities.
BSE said it has been receiving requests from trading members for withholding payout of funds and securities on account of unauthorised transactions or those on account of alleged fraud.
It also asked the brokers to provide a copy of the directions issued by police or any competent authority for the exchange to withhold payout of funds and securities.

"Trading members are hereby once again requested to note that the process needs to be followed well before the scheduled payout date of the particular security followed by the exchange," BSE said in the notice.
"If the direction issued by the competent authority is in order, the exchange shall issue necessary instructions to Indian Clearing Corporation (ICCL) to withhold release of payout of funds and securities in terms of such directions," the BSE notice said.
"ICCL shall inform the trading member once the funds and securities have been withheld in compliance with the direction issued by the competent authority," it added.
