Why three short averages rather than one, what their spread says, and at what point a trend is considered lost.
“This coin is trending.” Everyone says it, almost no one defines it. Without a definition the sentence means nothing: each person looks at their chart, sees what they want to see, and calls it a trend.
A usable method therefore starts with a mechanical rule — true or false, with no room for argument. The one used here fits into three exponential moving averages: 13, 25 and 32. It is the screener's main criterion, the one behind the “Valid setup” card.
The point of a mechanical definition is not to be right more often. It is to make your decisions comparable with one another. If “being in a trend” always means the same thing, then after fifty trades you can establish that your entries in that state fare better than the others — or worse. If the definition shifts with your mood, you learn nothing from your history: you are comparing different things.
It is also what makes a screener possible. A machine cannot recognise a “nice structure”. It can check whether price is above three averages. That is where the whole value of a mechanical rule lies: it applies to five hundred contracts in two minutes, without fatigue and without preference.
A single average gives a binary signal: above or below. Price crosses it often, in both directions, and every crossing looks like a signal while most are only noise.
Three closely spaced averages answer that problem simply: they demand agreement. Price can move above the EMA 13 on a single nervous candle; it rarely moves back above all three at once without something having genuinely happened. The filter does not make the signal earlier — it makes it cleaner.
There is nothing magic about 13, 25 and 32, and that should be said plainly: neighbouring periods would give comparable results. What matters is not the exact number but the fact that all three are short and close together: they describe the same thing — recent momentum — with three slightly different sensitivities. Their agreement is what carries the information.
Beyond where price sits, the distance between the three averages tells you something useful.
When they spread apart, the move is accelerating: each candle pulls away from the last, the fast average detaches from the slow one. The market is directional. That is pleasant to watch when you are already positioned — far less so for entering, because price is a long way from any pullback level.
When they tighten, the market is digesting. Recent volatility contracts, the three averages converge, price comes back to touch them. This phase is uncomfortable: it looks like a loss of steam. Yet it is where entries offer the best ratio, for an arithmetic rather than a prophetic reason — the invalidation point is close. Entering in contact with the averages allows a tight stop; entering after three candles of acceleration forces a wide stop, and therefore a smaller position or a larger risk.
A tightening does not predict which way the move resolves. It only signals that a resolution is approaching — one way or the other. That is information about timing, never about direction.
An entry rule without an exit rule is useless. The symmetry is natural: if “being in a trend” means holding above the short averages, then the trend is lost when a candle closes below them.
The word “closes” does all the work. Intrabar, price dips below the averages and recovers constantly; exiting on every wick means being shaken out over and over. Waiting for the candle to close costs a few percent on the real breakdowns, and avoids most of the false ones.
It is a trade-off, not a trick: you exchange responsiveness for reliability. Depending on the timeframe you decide on, the cursor moves — a 4-hour close takes you out fast and sometimes for nothing, a weekly close keeps you in the move but makes you give back part of the gain.
Three elements of the interface translate the above directly:
The stretch column completes the reading: it measures how far from the averages price sits, scaled by the contract's own volatility. It is the numerical version of the spread described above — a way to tell a crossing still close to its averages from a move that has already run a long way.
It is worth being honest about the scope of all this. Price above three averages is a statement about the recent past, not a forecast. The rule says nothing about the soundness of the project, nothing about the broader market context, and nothing about the probability that the move continues.
It fails predictably in two cases: directionless markets, where price crosses the averages both ways and triggers signal after signal; and violent reversals, where the exit arrives well after the top, by construction.
A trend filter is therefore only the first question in a series. It removes what does not deserve to be looked at — already a great deal when the universe holds five hundred contracts. The next questions concern the broader market context, the agreement between timeframes, and the moment of entry: each one is the subject of an article.
