Welcome onboard. I checked your platform with my mobile but seems the site can not be fully accessed with mobile phone but only desktop or laptop as the case maybe.
You are talking about testing an open order and I ask is your project on beta phase? Are you as well giving out your beta version of the site. While going through your site, I found a particular place of integration of wallet. Is it not more of granting you access to ones exchange wallet? What measures have you put in place security otherwise? Let us know with facts as this is a good project but you will have to prepare for the traffic and possibly high security tech to protect users account.
I will also advise you do a review so as to give room for more and better development and upgrade as well.
That is correct. The app may not be very accessible on a small screen. The problem is inherent to the app itself and not necessarily to the device in concern. There isn't enough space on smaller screens to fit all the columns. That's why the user will need to scroll horizontally to be able to view all the columns. We are still working on the UX though so hopefully we will come up with a solution to this problem.
The orders section is in beta phase. We have tested it with a few exchanges so far.
The API details pertaining to the exchanges entered by the user are stored in the database in an encrypted format. The users must ensure that they provide read-only access. We have applied security measures to ensure a data breach never happens but it is something that's not inevitable. CoinTracker recently suffered from a hack even with all the precautions. For this reason, it is extremely important to ensure that only read access is being given.
