Each stock may trade at different minimum lot sizes controlled by its price. This minimum lot size is called a Board Lot (see table below). If a stock's board lot is 1,000 then that is the minimum amount of shares that can be bought and any amount above this should also be traded in scales of 1,000. Thus an order to buy a stock with a board lot of 1,000 will reject an order to buy 1,500 and 3,200; but will accept 1,000, 2,000, 5,000 and above as long as it is wholly divisible by 1,000 and not leave any partial lots.
.
*The table below identifies the Board Lot size based on stock price and the corresponding tick sizes.
