Exchange Valet lets you set pending orders without using your balance. These orders are not on the exchange and waiting to be triggered once the price hits.
At the time of order execution, if you don't have enough available balance to execute the order, your order will fail. Let's look at some possible scenarios:
- You had a limit buy order and a stop loss with the same amount. Because your limit buy order did not fill completely, your stop loss failed trying to execute with the amount you do not have.
- You had two pending orders with the same balance, one executed and used the balance, the other tried to execute with no available balance and failed.
