The best thing about calypso trading is that it provides me with real time quotes for my stock market investments, which helps to keep track of them in one place at all times without having to constantly check multiple websites or apps to see what's going up/down! It also allows you access from any device so I can view anytime anywhere if needed (and this saves tons of paper). Sometimes there are glitches where some orders don't get filled right away but they usually fix those pretty quickly once notified by email.
Some features could be improved like being able to choose between different exchanges when logging into an account as well as allowing more than 1 currency within your portfolio would help make things easier too since sometimes i need both USD & EURO accounts open simultaneously just because certain trades happen only during specific hours depending upon exchange rates etc. But overall great product!! Definitely worth checking out especially...
