There is rarely a temporary disabling of any trading pairs on the exchanges. It can be due to absolutely different reasons. If this happens to you, you will receive a notification via Telegram (if you have it connected), by e-mail and you will see a notification in your account at the top of the screen.
Let's see what will happen with the trades.
If you buy a coin, and then the market goes offline - Steroid cancels stop loss that you specify in the task. "Trailing Stop Loss" automatically removes a tick from the fields: "Max Stop Loss" and "Fixed max Stop Loss." At the same time, Steroid leaves Take Profits. You can cancel the Take Profits (canceling the task completely) by going to the "Task List" and finding an open trade there.
This is done in order to save your deposit from possible losses. Since the moment of switching market online, the coin's rate behaves unpredictably and the minute candle can go very far down and you will loose funds.
