Write code of the contract for verification of validity of contract. In the case you have used brokerage services at CEB to buy or sell EUA, CER, wheat, corn, diamonds, or other commodity, this is the tool to verify contract price. If your brokerage partner did not give you contract code, it is possible that he was trading on his own account and you did not receive the best price he could offer you. In that case ask your brokerage partner to provide contract code for you, or contact Division of market control at Commodity Exchange Bratislava.
Application is able to verify all contracts since 2008-01-01.
