I'm checking order is placed with exchange or not after placing order. sometimes I get the order is placed but sometimes I didn't found order placed with exchange although the order placed successfully.
due to above issue software places the same order again, which is already placed.
Please do let me know how can I avoid this situation ? should I need to give some time before checking the placed order over exchange, if yes then what should be ideal time gap order placement and re-check of the same order?
