As per current exchange rules, investors get funds on a T+2 basis.
In financial markets, T+2 is a shorthand for trade date plus two days indicating when securities transactions must be settled… The most common current settlement period for securities transactions is two business days after the day of a transaction – which is widely abbreviated to T+2.

In the capital market, every trade undergoes a life cycle. This starts with the placing of a buy or sell order for execution and ends when the trade is settled. This process is called the trade life cycle. T+2 settlement cycle is followed in stock markets in India. This means that it takes two days for a trade life cycle to be completed—from initiation to settlement.

The first step in a trade life cycle is placing an order, which is followed by matching and execution of the order. The trade is then cleared by a clearinghouse of the stock exchange. The last stage is the settlement, which involves the pay-in and payout of securities and funds, on the second or last day of the trade life cycle. Trades that do not successfully settle undergo a process of auction of shares.
For institutional traders, the process of confirmation is done on a T+1 basis.

The first day of a two-day settlement period (T+2) starts on the business day following the day that security was purchased or sold. For example, if a stock is purchased on Friday at any time before the close of trade on that day, Saturday, Sunday, and public holidays are not considered business days, so the two-day clock starts running on the next business day.
