I believe that every change a well-established broker like Tredero makes is for the better.
Maybe as an already client of them you couldn't see the benefits of their redesign, but imagine if you are discovering now Tredero and go to their website and try to explore their trading terms or other perks… now it is much better and easier than it was. Plus, I like their new trading app, it is really a modern and simple trading solution.
In general, YES, I think they improved with the latest updates.

Honestly, I don't think it differs too much from the previous one. It didn't get better and worse, it looks like nothing global changed. XD
Anyway, we can see that Tredero company is trying to improve the quality of their services and I really appreciate it.
