A Muhurat trading session is conducted by exchanges every year on account of Diwali - Lakshmi Puja. Before the advent of electronic trading in the stock markets, trading would only take place in the designated trading halls of stock exchanges. Nobody apart from stockbrokers and their registered assistants would be allowed entry into the trading halls. Clients would have to stay outside the hall and get instructions/information relayed to the stockbroker with the help of the brokers’ assistants.
However, on Muhurat trading day stockbrokers could also invite some of their clients and friends into the trading hall to witness the open-outcry trading. One would be encouraged to buy a stock to mark activity and welcome luck for the next year. Check this post on Tradingqna from last year to read more about the significance of Muhurat trading.
This year the Muhurat session is being held on 27th October 2019 between 6:15 PM and 7:15 PM. MIS/BO/CO positions will be squared off 15 minutes before market closing. Check out the circulars for equity, currency, and MCX.
Also, if you’re trading through Zerodha, you don’t have to pay brokerage on any trades taken on this day. Check this post on Zconnect.
Note: Stocks purchased on 25th October 2019 (Friday) will not be available for selling on 27th October 2019 (Sunday) on account of a settlement holiday.
