Madam, no order may have been executed between 88.5 and 89.25 after you placed the order. Else ensure that the order has reached the exchange - have u got a exchange order id?
Why aren't my orders getting executed? I kept a buy order at 89.25 but it didnt execute whereas the price went from 88.5 to 91.5. The same thing happened with some of my orders.
Check with your broker/trading account provider, they might reply, "its due to a technical snag in our system, sorry for the inconvenince". Thats what I receive sometimes.
