Minimum balance is an absolute minimum amount of money you need to have on your exchange account to subscribe to copy trading or submit your strategy.
Kindly note that to be successful in copy trading, you might need much more than a minimum. Сompare your balance to the strategy total balance and see if they differ much. The strategy might have a big amount of money to trade with. And it uses only a fraction of it in single deals (1-2%). If your exchange balance is much lower, it might be insufficient to copy a particular deal. The exchange has a minimum amount for placing orders. When the trader makes an order for 5% of his balance — our system will take 5% of your balance to place the same order. If that 5% is less than the minimum amount, the exchange will not accept your deal.
