At the time an order/auto-exchange is triggered you will need to have sufficient balance in your account to perform the auto-exchange. If you don’t have the full balance you specified, the order would fail. You would then need to add money to your account and enter another order.
Daily exchange limit
For security reasons we limit the amount of exchanges / auto-exchanges to 30 in a 24-hour period. If an order is executed once you have exceeded this limit, it will fail and you will need to wait until the next day before entering another.
Crypto transaction amount limit
For security reasons only €15,000 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 orders are not executed until your account is unlocked. Once unlocked, your order will be executed the next time the specified rate for the pair is reached. You would not need to re-submit it.
Slippage only applies to the order types: Market Order and Stop Order, which are executed at the market rate. In a very volatile market, the current rate of the currency pair might have moved significantly in between the time your order level is hit, and the time the execution is attempted, even though this time window is very small. In this case, execution will not occur if the current rate has moved more than 0.75% for fiat or 5.0% for crypto from either side of your target value. Order execution will be attempted again once your target value is hit again by the current rate.
