check before open order

is there away of checking a condition before a pending order executes

ie pending sell order opened say st GBPUSD 1.44233 and current price is 1.44300 then price moves down to 1.44233 is there a way to check for a conditon before the order is executed ie

// check oder before execution
// is ma still in direction of trend
// if yes let order pass through if not cancell order

thank you

then i think you should use direct buy and sell instead of pending orders
