If your account was created on Binance after August 20, 2020 without a referral promo code, then you can use Finandy terminal absolutely free!
To check if your account is suitable or not, you can add the API key to the terminal, after 15-20 seconds reload the page and check in your account in the "Subscriptions" section whether Free subscription is activated or not.
If your current Binance account does not match and you still want to get a Free subscription, then you need to follow 3 simple steps:
Open trading in Futures WITHOUT referral codes (if you did this using the link from 1 point, then they will already be opened automatically)
Create an API key, add access to futures if necessary
In 15-20 seconds after adding the API key to the Finandy terminal, reload the page and check if you are a member of this program in your account in the "Subscriptions" section.
