I don't think that is a good idea.
curved monitors are ok (OK only !!) for watching films.
for trading, you want to see straight line as STRAIGHT LINE.
You don't want distortion !
Curves dont distort anything. They are designed to improve the viewing angle and flat monitors have the worst possible viewing angles.
The curve on both my monitors is probably less than 2 degrees and the change in viewing angle is incredible. It's incredible people believe these myths.
