It depends on which data service you are subscribed to.

“Basic” package subscribers do not have to pay for their subscription because it is provided for free. In this package, you can expect to receive updates at the beginning of each month.

“Standard” and “VIP” packages subscribers pay for their data every month/year depending on their subscription type (monthly or annual).

Subscription gives you two valuable benefits:

1. You do not have to prolong your access to the data service manually – it will be handled automatically 
2. You will be receiving the latest data, which is certainly the most important. The markets are constantly changing and that is why the latest historical rates create the biggest proof of whether your trading system is capable of bringing profits or not. 

You can switch your subscription off anytime you need to. Please note that in this case you will not be able to receive the latest updates.
