Stop loss and Take profit in MT4
Stop loss (SL) is a type of order that tells the broker to automatically close the order when the price drops (in the case of a buy order) or rises (in the case of a sale) to the level we indicate.
Take profit (TP) is an order that tells the broker to close the order when the price reaches a certain profit level.
Avoid loss by moving SL
You can specify TP and SL levels both when you place your order, but also later in the trade, even when the position is already open. A popular method of risk management is to move the stop loss level to the so-called "Break even", ie the level of opening a position when the result of the position is already positive, but is still within a certain distance from the take profit level. Such a procedure ensures that even if the market turns against our position, we will avoid a loss and the transaction will close with a result of "0".
