MT5 provides 6 pending order types, namely:

Buy Limit — limit price to buy
A trade request to buy when the bid price is equal to or less than the price specified in the order. The current price is higher than the price in the order. Typically, this order is placed in anticipation of a safe price, that is, a pullback to a certain price before rising.

Buy Stop — buy stop loss
A trade request to buy when the Auction price is equal to or higher than the price specified in the order. The current price is lower than the price in the order. Typically, this order is placed in anticipation of a safe price, that is, a sustained rise after a breakout above a certain level.

Sell Limit ― limit selling
A trade request to sell when the bid price is equal to or higher than the price specified in the order. The current price is lower than the price in the order. Typically, this order is placed in anticipation of a safe price, i.e. rising to a certain price before falling.

Sell Stop — sell stop loss
A transaction request to sell when the bid price is equal to or lower than the price specified in the order. . The current price is higher than the price in the order. Usually, this order is placed in anticipation of a safe price, that is, a continuous decline after breaking through a certain price.

Buy Stop Limit ― limit price buy stop loss
This is a combination of the two. The first type breaks through upwards and then places a Buy Limit pending order. As long as the future bidding price reaches the breakthrough price (Price field) marked in the order, a Buy Limit pending order will be placed at the price specified in the Stop Limit field. The breakthrough price should be set above the current bidding price, while the Stop Limit price should be set below the breakthrough price.

Sell Stop Limit — limit selling stop loss
Sell Stop Limit Order – This type is a down-break pending order that places a Sell Limit pending order. As long as the future bidding price reaches the breakthrough price (Price field) marked in the order, a Sell Limit pending order will be placed at the price specified in the Stop Limit field. The breakthrough price should be set above the current bid price, while the Stop Limit price should be set below the breakthrough price.
