At the time an auto-exchange is triggered you will need to have sufficient balance on your account to perform the auto-exchange. If you don’t have the full balance you specified, the auto-exchange would fail. You would then need to add money to your account and schedule another auto-exchange.
For security reasons we limit the amount of exchanges / auto-exchanges to 30 in a 24-hour period. If your auto-exchange is triggered once you have exceeded this limit, it will fail and you would need to wait until the next day before scheduling another.
For security reasons only €10,000 worth of crypto can be exchanged in any individual exchange. If you attempt to exchange more than this amount the auto-exchange will fail.
If your account is locked for any reason, for security reasons auto-exchanges are not triggered until your account is unlocked. Once unlocked, your auto-exchange would again be available to be triggered the next time the current rate for the pair touches your target value. You would not need to reschedule it.
In a very volatile market, the current rate of the currency pair might have moved significantly in between the time your price target is hit, and the time the auto-exchange is attempted at the current rate, even though this time window is very small. In this case, auto-exchanges will not occur if the current rate has moved more than 2.5% either side of your target value. The auto-exchange would be re-attempted once your target value is hit again by the current rate.
