How to convenience Broker that trades taken all solely by us and not by some third party.
How to convince a broker about that ? Simple: follow the T&Cs about unauthorized trading
But yeah if you are a bit on the technical side and understand the net structure a bit you can immediately see that it is their main concern.
- OTP, tokens, two-factor authentication etc are of no interest because that is information that can be communicated to someone else using phone, skype or whatever. That is usually used i.e. for banking stuff where YOU want to be the only one accessing the resource
- Proxies, VPNs etc are means that can hide the real location of someone and can be easily identified as such.
- VMs and VPSs can be accessed by other people.
- Devices are mentioned so probably device fingerprinting is going on there (valid for the one above).
- I suspect that the stuff about the 500kms (within same country) has to do with ipv6 mobility features such as potential roaming functionalities, depending on the mobile carrier etc, that goes hand to hand with the previous a bit too.
- There are other methods but very intrusive ...
And by the way China is supposed to block of all domestic VPNs by Feb 2018, and it should be enforced by all chinese local carriers, I think.
