AvaTrade offers two kinds of stop orders, Stop Losses (S/L) and Entry Stops (E/S).
A Stop Loss is an order to close a position at a predefined rate as the price of an asset moves unfavourably for the client’s position. It is placed at a rate which is less favourable than the current market price.
An Entry Stop is an order to open a trade at a predefined rate as the price of an asset moves favourably for the client. AvaTrade does not guarantee its Stop Losses or Entry Stops.
If there is a sharp market move, and the current price of an instrument breaks through the clients S/L or E/S, it will be executed at the next available price.
