To assist the members to know their margin requirement for their trades in regard to their transactions in Government Securities, CCIL has designed a software which can provide on-line information about margin requirement of the members based on their outstanding trade positions. The system operates on a personal computer having Windows 98 or above as its operating system and having MS Access 1997 (or higher version) loaded into it. Members are provided with all master files (like ISIN Master, Margin Factors, MTM Price, Eligible Securities & haircut rates) by CCIL in .CSV format through its report server as at the end of every day. Apart from the upload of these master files, members would only have to enter particulars of their trades as it happens. Moreover, the entry of the trades could also be achieved through the file upload or NDS file Upload facility provided in the software. As the particulars of the trades are entered, members get information regarding their margin liabilities.
