Wealthybot only takes a profit when you receive a profit from liquidating/closing a position that has a profit margin. We take our portion of the profits in "credits" 1 credit is the equivalent to 1 unit of currency. WealthyBot will remove 20% of the profit you make in credits. You must have credits to cover the profit of your liquidated position or Wealthybot will not make the trade. 

For example, if you have €20 in profit Wealthybot will take €4 in credits or 4 credits.
