When market is under fast movements and server is busy ... execution of order takes few seconds ... it is essential

BUT most of brokers use this trick to execute the order in the worst price (for the trader). In other words, they keep the order for seconds to find the worst price.

In my experience, FIBO execute the order exactly in the first price, even when the price is moving in other direction.

Since this is a very important feature about brokers (particularly for scalpers) I disclosed this experience in this thread
