At this time, Advanced Trade does not have the concept of stop-loss orders.
Advanced Trade works on the premise that sellers want to sell for a high price, and buyers want to buy for a low price. This is why when you place a sell order for a price that is lower than the highest sell order in the order book, it will likely execute immediately.
Similarly, if you place a buy order for a price that is higher than the lowest buy order in the order book, it will likely execute immediately.
The rules required for a stop-loss order currently do not exist in the Advanced Trade feature.
