Say you're trading SBI intraday in the cash segment and want to buy or sell 2000 shares to be squared off by end of day. In a trade like this, does your order get filled in parts (e.g., 1000 shares, 500 shares, 300 shares, 200 shares), or do you get complete fill of 2000 shares in one go? What's your experience while trading highly liquid stocks in the cash segment?
