Last dealing time refers to the deadline by which investors can place trades on a particular security or financial instrument in order for the transaction to be processed on the same day. This is also known as the cutoff time for transactions.

The last dealing time varies depending on the type of security or instrument being traded, as well as the exchange or market on which it is traded. For example, the last dealing time for stocks on the New York Stock Exchange is 4:00 pm Eastern Time, while for futures contracts on the Chicago Mercantile Exchange, it may be earlier in the day.

It is important for investors to be aware of the last dealing time for the securities they are interested in trading, as failing to place a trade before the cutoff time may result in the transaction being processed on the following business day or at a different price. In some cases, missing the last dealing time may also result in the trade being cancelled altogether.

Overall, understanding last dealing time is a crucial aspect of successfully trading financial securities and instruments.

The last dealing time in trading typically refers to the cutoff time for placing orders to buy or sell securities on a given trading day. This time varies depending on the market and the asset being traded. In most stock markets, the last dealing time is shortly before the market closes for the day, often around 4:00 PM local time. However, for some markets like the foreign exchange (forex) market, trading can continue 24 hours a day, five days a week, so there isn't a fixed last dealing time. It's essential for traders to be aware of the specific trading hours for the assets they are trading.
