An execution order (specifically a tick-senstitive order) that triggers the purchase or sale of securities if the market moves up by a tick. Uptick orders come in two broad types: buy uptick orders and sell uptick orders.
Uptick orders constitute traders’ bets or expectations that the trade price will be higher than the last different price (before the tick change). These orders are instrumental for traders who want to sell at higher prices (more than the current ask prices), but they are not available to cancel or re-submit their orders if prices move down.
