How to read any MAMAY screener

7 min read · The score is about the strength of the move; the side comes only from setups. The core idea behind every screener.

Words in this lesson (11)

Gap — A jump in price: today trading opened noticeably higher or lower than it closed yesterday. Closed at 100 yesterday, opened at 108 today — an 8% gap up.

Long — Buying in the hope that the price will rise. Buy lower, sell higher.

Short — Selling in the hope that the price will fall: you sell something borrowed, then buy it back cheaper. You make money when the price drops.

Stop — A price chosen in advance at which the trade is closed at a loss, so the loss doesn't grow bigger.

Volume — How much money or how many units changed hands over a period. A move on high volume is more reliable than one on low volume.

Level — A price where the market has already turned before. Support is below the price, resistance is above it.

Breakout — The price has gone through a level and held beyond it.

Setup — A ready trading rule: under what condition to enter, in which direction, where the stop and the target are.

Screener — A filtering program: it scans hundreds of stocks or coins and shows only those that match the given criteria.

Premarket — Trading before the exchange's main session opens. There are few participants, and the price moves easily.

Fee — What you pay the exchange for every trade — both on entry and on exit.

Two different questions

When you look at a stock or a coin, you're really asking two things:

US Board: the score is about the strength of the move, the "Side" column comes only from setups

Will there be a strong move?
In which direction?

Beginners think it's one question. MAMAY answers them separately — and that's the main thing to understand about all of its screeners.

The score answers only the first question

Almost every screener has a "Score" column from 0 to 100. It says: how likely it is that the price will move noticeably today.

An example from a test on US stock history (1,982 stocks):

What was there in the morning	Share of stocks that moved 10% or more that day
no gap and no high score	9%
high premarket score (60+)	27%
a gap of 5% or more	61%
both a gap and a high score	79%

The score works: the more signs line up, the more often a strong move happens.

Now the second number. Among the stocks where everything lined up, only 31% closed above the signal price. In other words, "everything lines up — I'm buying" lost more often than it won.

A high score is not a buy signal. It's a signal that says "this is worth watching".

Setups give the direction

A setup is a specific rule: "if this happened — we enter there, the stop is here, the target is there". Every setup in MAMAY has its own statistics: how many times it occurred, what share of trades were profitable, how much it brought on average after fees.

The "Side" column shows long or short only when such a setup has triggered. If there's no setup, the column is empty — and that's an honest answer: "a move is likely, the direction is unknown".

How to use this

High score + a side — a workable idea. Open the chart and look at the entry, stop and target levels.
High score, no side — trade from levels (breakout or bounce) with a small size, or just watch.
Low score — skip it.

Where the statistics come from

MAMAY records every signal in a journal by itself and later checks how it ended. That's what the "Signal performance" lesson is about.
