mpriors

Market analytics

A scope for the market.

mpriors shows what the market is doing and how unusual it is. Every price move, every day’s volume and every swing in volatility is measured against that security’s own history, so an ordinary day and an exceptional one look different at a glance. The method is always one click away, and mpriors never tells you what to buy.

How to read it

Three questions, in the same order every time.

What happened?

A one-sentence first read of the day, then the indices, sectors, rates, commodities, futures, world markets and crypto, each as a card with its move and its session.

Is it unusual?

Each card sets today’s move, volume and volatility against that security’s own history. Inside the usual range is an ordinary day for this name; outside it is worth a look.

What moved it?

Put names in a basket and every move splits in two: the part the group explains and the part that was the stock’s own.

The card

Usual, for this name.

A card carries three reads you learn once and then scan: the coloured pill is the move, the VLM rail is today’s volume against the last 90 sessions, and the IV rail is today’s volatility against the last two years. The blue triangle is today; the outlined pill is the usual range. Inside the pill, an ordinary day.

Baskets

The group, or the name itself.

A basket is a set of names you choose to read together: semiconductors, your holdings, a theme. Each name’s move is split into the part the rest of the basket explains and the part that was its own, so the one stock that moved for its own reasons stands out from the ones that moved with the group.

change = group + solo

Volatility

How rough is the water?

mpriors names volatility with five words, from glassy to heavy, by where today sits in the name’s own two years. The ribbon shows a year of it against that range, beside the volatility the option market is pricing for the month ahead.

It describes. It never predicts.

No signals, no targets, no “buy”. mpriors measures what happened and how it compares with what usually happens, names the window and the method behind every number, and leaves the decision with you. Read the method →
