They do not deliver what they claim they will deliver
Service use: Demo
Length of use: 0-3 Months
I purchased a license to use the Noble Impulse indicator on their website. What you are purchasing "according to the website" is a lifetime license to use their indicator.
However, once you buy this license there are additional things that you find out such as you can only get three license keys (one demo and two live accounts). The key is based on your Metatrader account name and account number. So, rather than a lifetime license, you are getting a license that will work for as long as the company is around and still responding to emails. As long as you don't change brokers you may be ok.
I am not commenting on how well or poorly the indicator works, but given they are not upfront about the licensing of the indicator you need to be sceptical.
