A cross on a thin name

Every Confirmation Desk pack has a third sheet that people dislike. It is a smaller cash name with long stretches of almost nothing, then a gap, then another stretch. We include it because technical analysis training that only uses busy index futures teaches a false kind of neatness. Moving averages look decisive when a session trades all day. They look decisive, and are not, when a name trades in spurts.

Three closes and a gap

On a recent packet the 20-period simple average crossed above the 50 while the 50 was still falling. Three daily closes then printed above the longer average. On a liquid name that sequence would at least earn a conversation. On this sheet the middle close was a gap from the open, the volume of shares was a fraction of the name’s ordinary thinness, and the next session opened back under both lines.

A cross is a description of two calculations passing each other. It is not, by itself, trend confirmation. Confirmation in our checklist asks whether closes are holding on the far side of the averages and whether the longer average’s slope has actually turned. Three prints can satisfy a hungry reading and satisfy nothing else. The gap back is the market declining to continue a story that only existed on the smoother line.

Thin names make this worse because a single lot can move the close. The average then digests that close for twenty or fifty sessions, long after the lot is irrelevant. You end up with a curve that remembers a spike the order book has already forgotten.

How the desk marks it

Han Sora has the group write one of three words under a cross: held, failed, or too thin. “Too thin” is allowed when you cannot find several ordinary sessions on each side of the cross. It is not a failure of nerve. It is a refusal to treat a calculation as a crowd.

If you trade only liquid names, do the exercise anyway. The habit of asking whether anyone was actually there is the same habit that saves you on a holiday session, a halted afternoon, or the first day after a rumour. Moving averages will still draw themselves. Trend confirmation is the extra sentence you insist on writing underneath.
