"For" with 3 Apikey runs all purchases only for the first (apikey) account of the list.

[csdiftec]

I have 3 'ApiKey' different accounts and 1 invalid, but no matter what I do in the for the purchase is only posted to the account of the first ApiKey, example; if the first one is invalid all are invalid, if you launch the purchase and it is validated, all are being validated for the same account but with the correct values ​​of each purchase.
I do not know how to close or open each "session" something of the type.
What should I do?

              List<Ticket> listTicket = (List<Ticket>) ticketServiceImpl.findAll();	
               for (int i = 0; i < listTicket.size(); i++) {

			String apiKey = listTicket.get(i).getUser().getApiKey().toString();
			String secretKey = listTicket.get(i).getUser().getSecretKey().toString();	
							
			buy(currencyPair, stringAmountBuy, apiKey, secretKey, purchasePrice);			
			}
	     }

`public class Buy {

public  void buy(String currencyPair,String amountBTC,String apiKey,String secretKey,BigDecimal purchasePrice) {

	BinanceApiClientFactory factory = BinanceApiClientFactory.newInstance(apiKey,secretKey);
	BinanceApiRestClient client = factory.newRestClient();
	
	String purchasePriceString = String.valueOf(purchasePrice);
	
	NewOrderResponse newOrderResponse = client.newOrder(limitBuy(currencyPair, TimeInForce.GTC, amountBTC, purchasePriceString));

	System.out.println("Class buy..."+ newOrderResponse);
		
}

}`
