I want to know what is a "credit" in MQL 5. Is it one dollar ? When i want to buy something for 30 credits / month it means i must pay 30 $/ month ?
I am waiting for answer
yes ... but you may receive the credit using many actions (deposit to your mql5 profie is just one of the action) ... you are receiving the credits by posting on the forum, creating the threads, polls, posting to your profile and more and more ....
