MWPL = Market Wide Position Limits

Market Wide Position Limits (MWPL) is a regulatory mechanism used in derivatives markets, particularly in India's National Stock Exchange (NSE) and Bombay Stock Exchange (BSE), to prevent excessive speculation and concentration of open interest in a particular security.

MWPL is the maximum number of open positions (futures & options contracts) allowed across all market participants in a particular security. It is typically set as 20% of the free float market capitalization of a stock.
