fund account

 

I have 30USD in my mql5 account, but cannot buy an indicator for 30USD, because I don't have enough funds !  Please sort this out.

Your 'automated robot' is probably the worst in the entire internet.

 

It may be related to VAT (if the system indentified you for VAT so the price may be more than 30 for example) .
Anyway, you can ask the service desk about it:

for financial issues, please contact the Service Desk — Contacts and requests >> Create a request >> Finance >> Other question >> write your message — https://www.mql5.com/en/contact

 
Yes, as Sergey already mentioned, it is related to VAT, your $30 purchase has an extra $5.70 VAT added.
