Hi guys,

I am trying to purchase the Expert Advisor [name was deleted by moderator]

but I cannot buy it.. :(

I got this error message PAYMENT FAILED and when I looked in the Journal,

I saw this error message:

MQL5 Market error purchasing product [12840] - Error occurred

I am logged into the MQL5 Community and I was using Citibank MasterCard and also used a VISA card.

P.S. I am running an instance in the VPS for Amazon EC2. Is there a security restriction there that I need to adjust?

Thanks for your help!

Best regards,

maybe The EA has been removed, so you cannot purchase it.

Get in touch with developers using Service Desk!

MetaQuotes Software Corp., 2010.03.09 12:10

Any new software inevitably contains bugs that are not always possible to detect even under the most rigorous in-house testing. We therefore attach great importance to all user reports about issues in our programs and try to answer each one of them.

In order to improve feedback from MetaTrader 5 end users, we have implemented Service Desk section in each MQL5 Community user Profile. Any user can send a Request about problem discovered in our product.

Why a new section, if any registered user can write an error message on the forum? The fact that Service Desk is directly integrated into our in-house TeamWox GroupWare, that is used by our developers. This means that every working day in MetaQuotes Software Corp. begins with the overview of received requests about problems found in our products.

For this very reason we invite you to report any bugs directly to our developers via Service Desk. Your message will be immediately accessible to our Quality Assurance, Technical Support and Trading Platforms departments. Each request sent from Service Desk is compulsorily treated, and is either closed after fixing the problem, or queued for making a decision in the future.

We ask you to report each found error in a separate request, while adhering to certain rules:

  1. The request contains description of only one problem. It will allow us to focus on its solution and during its processing and discussion not to specify what was corrected or was unable to reproduce.
  2. In request subject please specify a brief description of problem, so we can always find it among other requests.
  3. In the beginning of a request briefly describe the problem. For example:
  4. Give a detailed description of actions taken to reproduce the problem. Complement your request with screenshots (if necessary) that are referenced in description. For example:
  5. Describe the achieved result. For example:
  6. Describe the expected result. For example:
  7. Provide the necessary details to reproduce the error. For example:
  8. Provide additional details that can help find a solution. For example:

All these recommendations are compiled using our own long-term experience of communicating with customers, and we will be grateful to you if you adhere to them.  Please, notify us about found errors. We can find and fix them as soon as possible only with your assistance. With your help we will do our best to create the superior trading terminal for You!
