It is the so-called smart price for copy trading. Smart price is a cost for copying a strategy based on the cost set by its trader and subscriber’s balance in the exchange wallet.
There are different coefficients and costs for copy trading depending on the balance of the wallet you'll connect to a strategy. The lower your balance, the lower the subscription cost and vice versa.
Please read the article about payments on Coinmatics to get a better understanding of the Smart Price and how it's calculated.
