"BSE StAR MF has processed over 50,000 orders on a single day on August 10, 2015," the exchange said in a statement.
Prior to that, the exchange's mutual fund platform executed over 44,000 orders on March 10, 2015.
The volume of mutual fund transactions routed through this platform has been consistently increasing since 2009-10, it added.
BSE, in May, had introduced an 'overnight liquid fund' product on its mutual fund platform.
The risk-free product enables small investors, corporate or a trust to invest even for a period of a single night in liquid funds anywhere in India.
