The one-line version

The rule this asset runs on

The daily boards decide who is eligible. The week’s shares set the order.

One question, answered by one number

Membership and order are the same figure: every share that traded through the name across the week’s five sessions, added up. A name has to keep showing up to reach the top. In the week of August 24, AEFI and GGSM led on 1.4B shares each.

This board used to answer two questions at once: volume chose the twenty, then weekly percent change re-sorted them. That is worth saying plainly now that it does not. At the $0.0001 price floor a single tick is a 100% move, so the old ordering put three names that had ticked one increment at the top of a board about volume. They now sit at nine, ten and thirteen, where their share counts put them.

How it differs from the Sunday board

Identical construction to Weekly Dollar Volume Leaders with one substitution: this board counts shares, that one counts dollars. Running both across a weekend is deliberate. The two routinely share fewer than half their names, and the difference between them is the same story the daily pair tells: where the certificates moved is not where the money moved.

Where the numbers come from

OTC Markets for the week’s trading, and an independent market-data provider for the weekly open and close. The weekly total counts every session in which the name reached a daily board, not only its strongest ones.

Three checks sit between the sources and the board. The price range printed at the foot of the asset is enforced, so a stock quoted below a hundredth of a cent, or above a dime, does not appear however many certificates changed hands. A name whose busiest session of the week carried only a handful of trades does not appear either, because a block cross is not a market. And a quoted price that disagrees with what the stock actually printed that week loses to the tape.

What is in the post

A fixed caption stating the selection rule, the week range naming the trading days covered, then the twenty symbols in board order, most shares first. Only rank one carries a cashtag.

The caption does not change, because the selection rule is the thing people get wrong and it is worth repeating every week.
