Each exchange allows a different number of active Stop Orders (conditional orders) per symbol.
If a trade didn't open or an order was canceled with this status, it means that you reached the exchange limit of the allowed number of active Stop Orders per a certain symbol.
Cornix uses Stop Orders (conditional orders) in the following cases:
1. Stop-loss orders.
2. Active trailing Entry and trailing Take-Profit orders.
3. Breakout trade entry orders.
