The side that crossed the spread to make a trade happen. The aggressor is what moves price; the resting side is what absorbs it.
The aggressor is whichever side crossed the spread to make the trade happen. It is the only half of a trade that tells you anything directional — the resting side did not choose that moment, the aggressor did. Every soldier advancing on this board is an aggressor; which direction they walk is which side ran out of patience.
Every idea on this page is something you can see on a live tape rather than take on faith. The board draws real executed trades as an army: buyers advance from the left, sellers from the right, and the glowing line between them is the price. Here is how to read it.
Now go watch the word happen. The live board is free for XRP — no account, no sign-up.
