Tested — does not work

Breakout from a tight range after a long consolidation

The classic move — price sat in a tight range for a long time, left it, so you go with the exit — turned out not to be a property of the coin at all. It is a way of guessing the moment when the whole market moves.

Why it sounded right

The mechanism looks physical. While price sits in a range, buyers and sellers are balanced. Orders pile up at the edges: some waiting for a bounce back inside, others protecting positions just past the boundary. The longer it sits, the more of that piles up. Leaving the boundary works like a trigger: the protective orders fill at market, the ones who bought the bounce give up, and the same flow pushes price further. That is where the feeling comes from — the first exit from the range is the moment the resistance ran out.

The move is easy to mechanize, and on the first runs it behaves exactly as advertised. The range is defined unambiguously: it lives as long as its width stays under a threshold, and it counts from a few days old. A breakout is a bar closing beyond the boundary with a margin, so a random poke does not count. The exit is a small fixed target, or a trailing stop armed exactly at that target. In that form the rule was profitable across timeframes, across range widths, across minimum lengths — not in one lucky setting, but broadly. That convinces too: a profit that does not depend on tuning is usually taken as a sign of a real mechanism.

On top of that, the rule matches personal experience. Take your own old entries, the ones made by hand and by feel, and more than half of them line up with what such a detector flags. The "I already do this, now I just have rules for it" feeling is very strong — and it is exactly what stops you asking the one question that matters: why does this particular coin belong here?

How we tested it

The control that was missing at first: same minute, same side, a different coin. Take every signal, and instead of the coin where you found the range, enter a random other coin — same minute, same side, same exit rule. If the range and its breakout mean anything, the result on somebody else's coin should sag. The second control is the mirror image: same coin, but a random moment instead of the signal. The third: execute every single signal on one big liquid instrument.

Then a separate check: compare every trade against simply holding bitcoin over the same window, in the same direction, with the same fees. And the last and most uncomfortable one: fold the rule into a portfolio where the capital gets divided between simultaneous signals, instead of adding up percentages across all coins as if money were infinite.

How it ended

A random moment on the same coin gives zero — so the moment is not chosen at random, the rule really does find the time and the side. But somebody else's coin in the same minute gives you almost the full result. Every signal executed on one instrument gives as much as it did on the "native" coins. The contribution of the coin itself is zero. That holds for large caps, mid caps, and genuinely small ones.

So this is not a range breakout. It is a market-moment detector. The biggest coin's own move over a fixed window from entry is larger than everything the rule earns. Widening the universe does not spread the risk: at peak you have dozens of positions open at once, and that is one bet placed many times — the portfolio drawdown grows with the number of coins, it does not shrink. Then the arithmetic of money finishes it off: after dividing the capital between simultaneous signals, you are left with less than a simple trend rule on one big coin gives you, at a deeper drawdown and with constant work. A live run, started separately, came out flat against the risk it took over several weeks, and was switched off.

One caveat has to be named: the "it collects the general move" conclusion is proven for sells. For buys it is not shown — their simultaneous trades are not tied to each other, which is why somebody else's coin cannot reproduce them by construction. Buys are covered in a separate article, and there something else kills them.

What this teaches

More in this section

A long shelf, then a break upward
The idea: price sits in a well-worn range for months, and leaving it means a run to the next such range. When we tested it, breaking out of the shelf paid exactly as much as a random day on the same coin.
Big orders in the book as a reference point
The idea: a big order in the book is a level price will bounce off, or a level it will aim for. When we tested it, price reached such a wall no more often than it reached a randomly picked level at the same distance.
Buying into a vertical spike
The idea: the coin has gone vertical, so a move has started and you should get on board while it runs. When we tested it, buying the spike was not a zero but a loss: far fewer trades finished up than with a random entry.
