Realized profit or loss in ICICI Direct is the actual profit or loss made after a trade is completed. Unrealized profit or loss is something you are making while holding the shares.
For example, say you buy 100 shares of a company at Rs 50. In a week, the price of the stock moves to Rs 60. You are still holding the shares. Your unrealized profit would be (Rs 60 - Rs 50) X 100 = Rs 1,000.
Now next week, you sell the shares at Rs 63. Whatever money you make or lose after the trade is complete is your realized profit or loss. In this case, when you sell shares at Rs 63, your realized profit would be (Rs 63 - Rs 50) X 100 = Rs 1,300.
