Why track large trades

Yesterday's large trade is today's price move

Large trades move prices — often slowly. Even yesterday's data shows you which markets are attracting serious capital. Sign up to see the 10 best trades from yesterday.

A single large trade could be noise. Thousands filtered by size show where conviction is building.
