- Learnability: The UI is self-explanatory and easily learnable. Labels/links are concise, and the UI does not use terms that the typical user would fine unfamiliar. The interface is consistent across pages, and pages are organized into tabs intuitively.
- Visiblity: The UI shows data that is either public, or private and relevant to the currently-logged-in user. There is nolittle irrelevant information.
- Efficiency: Every action can be done using just a few clicks from the home page. Information is presented in a straightforward manner, so the user does not have to scroll far up or down to find the appropriate buttons.
- Error Prevention: Any actions that the user can take that can have negative consequences require confirmation through a pop-up.
Cons
- Learnability: There are noexplicit instructions on how to use the UI. The UI assumes the user has some idea about how a market works.
- Visiblity: Users can only find out if a counterparty has proposed a trade by visiting the correct page on the website.
- Efficiency: Actions are entries in the table, and can be hard to click on if the user has small magnification selected in the website.
- Error Prevention: The user can easily become accustomed to the pop-up. Since this is the only form of error prevention, an experienced user might automatically confirm without actually making sure his numbers are correct.
