# How does the calculation of the profit work?

The profit determination is as follows: Suppose you have indicated that the trader is allowed to sell at 1.5% profit and that the average purchase amount is € 100 per trade. 

The trader then notices a purchase moment for a crypto coin and makes the transaction. He gives an order for € 100 purchase. However, the exchange charges you 0.25% transaction costs and debits this from your free balance. In the transaction screen it appears that you have purchased for € 100 (while the actual costs are € 100.25). 

When will the trader see a 1.5% profit? Once the value of the transaction is $ 101.50 (100 \* 1.015), the bot is allowed to sell. The profit that is made is gross, because the total transaction costs (on average 0.5%) have yet to be deducted. Your return rate must therefore be higher than 0.5% to actually make a profit.
