It's about having fun
Test, track, and improve your judgment ability, live and in direct competition with people from all around the world.

It's about your life
Life is a series of decisions. On the financial side we often compete with others, and seeing most clearly is crucial for success. This competition of judgment is what Aquinium is all about.

It's about sharper judgment
Every round sharpens your sense of value under pressure, against real people and computer opponents. Aquinium was founded by Ulrik W. Nash, PhD, and is built on his AQ Model of intuitive judgment.
How it works
Three steps. Every round.
Appraise
Study the stimulus and give your intuitive estimate of its true value before the clock runs out.
Trade
Meet an opponent — human or AQ Model — at the midpoint price and decide how much to buy or sell.
Climb
Judgment and market Elo ratings update every round. Track your profit and see where you rank.
Human opponents
