There are six main types of orders when trading digital currencies: limit orders, market orders, advanced limit orders, take profit and stop loss, bidirectional take profit and stop loss, and mobile take profit and stop loss.

Below are the specific rules for these six orders
Limit orders are orders that are executed after reaching a specific or better price.
A limit order is an order to buy or sell an asset immediately at the current market price.
Freeze orders according to limit orders
Can only place orders, cannot accept orders. Entrustment enters the order book. If it is directly matched with existing orders, the order will be cancelled
Check the order quantity. If the order quantity is less than the current transferable quantity, it will be executed. If the order quantity is greater than the current transferable quantity, it will be cancelled.
If the order is triggered, cancel the remaining quantity in the order directly after partial transactions
Stop-profit and stop-loss "orders refer to pre-set trigger prices, order prices, and order quantities after triggering. When the latest price reaches the trigger price, an order will be placed at the pre-set order price, which can be a market order or a limit order. It can be a separate take-profit and stop-loss order, or a take-profit + stop-loss order
1. Buy with stop loss and take profit. You can choose to trade with amount or quantity
After placing an order, assets will be frozen. If the order price is the market price and the transaction is made with quantity, the trigger price will be frozen by the amount of quantity. If the order price is the limit price and the transaction is made with quantity, the amount of the order price will be frozen by the amount of quantity. If the order price is the market price and the transaction is made with the amount, the frozen amount will be used to buy at the take-profit trigger price or buy at the stop-loss trigger price, and then the order will be sold. If there is not enough available balance at the end of the take-profit and stop-loss period,
2. Sell with stop loss and take profit. Only trade with quantity
After placing an order, freeze the amount of assets entered. Sell at the take-profit trigger price or sell at the stop-loss trigger price, whichever price is reached first, triggers the order first. After triggering, sell the order. If the available balance at the end of the take-profit and stop-loss is insufficient, the order cannot be sold
1. Two-way stop-profit and stop-loss buying. You can choose to trade with amount or quantity
The take-profit trigger price needs to be lower than the market price, and the stop-loss trigger price needs to be higher than the market price. After placing an order, the assets will be frozen. If the order price is the market price and the transaction is made with quantity, the trigger price of the higher price will be taken as the standard, and the amount of the trigger price * quantity will be frozen. If the order price is the market price and the transaction is made with quantity, the frozen amount will be triggered first at the price of buying at the take-profit trigger price or buying at the stop-loss trigger price. After triggering, the order will be sold. If the available balance at the end of the take-profit and stop-loss is insufficient, the purchase cannot be made
2. Two-way take-profit and stop-loss sell. Can only trade with quantity
The take-profit trigger price needs to be higher than the market price, and the stop-loss trigger price needs to be lower than the market price. After placing an order, freeze the amount of assets lost. Sell at the take-profit trigger price or sell at the stop-loss trigger price, whichever price is reached first, triggers the order first. After triggering, sell the order. If the available balance at the end of the take-profit and stop-loss is insufficient, it cannot be sold
Mobile stop loss is a type of stop loss that tracks market prices. It sets a price distance or ratio in advance and automatically executes a Market Order when the market price reaches the preset level.
Mobile take-profit and stop-loss can only be used in Market Order. It can only take-profit or stop-loss, not take-profit + stop-loss.
You can choose the activation price or not. If you don’t choose the activation price, the order will be activated after placing it. If you choose the activation price, the order will be activated when the market price reaches or exceeds the activation price. Without activation, there is no trigger price.
Activate
Trigger
The trigger price changes with the price after placing an order.
If the quantity and amount of buying and selling are sufficient, follow the order quantity. If the assets sold are insufficient, sell them all. If the amount of buying is insufficient, buy them all.
For example, if the user sets to sell 1 BTC, but only 0.5 BTC is triggered when the order is placed, then sell 0.5
The user sets up to buy 1000U of BTC, but when the order is triggered, there is only 500USDT, so they buy 500USDT.
