Always and everywhere there are traders who don't have enough financial instruments.
You probably know them. They trade a large number of orders on all possible financial instruments.
But I belong to those traders who use only 2 - 3 financial instruments in trading. For me trading conditions are more valuable than a variety of assets. Although this broker has both and excellent.
So, I trade only a few instruments and it allows me to analyze them in more detail and make more correct trading decisions.

I wouldn't say so frankly speaking.
But on the other hand there wasn't a single forex broker that could satisfy all my needs in regards to the amount of tradable assets.
So it's not perfect and there is definitely room for development.
However, there is no such thing as a perfect broker.
