A deep drawdown plus a failed spike up

A recognisable bearish chart shape: the coin fell far from its yearly high, then bounced sharply and gave the bounce back. The idea is that this picture tells you something about what comes next. The test showed it tells you nothing.

Why it sounded right

The shape reads at a glance. Price far below the yearly high, the moving average pointing down, and on top of that a fresh push up that failed and left a lower high than the one before. Your eye fills in the story immediately: buyers tried to turn it, could not, so the seller is stronger. Two opposite conclusions follow, and both look reasonable — either "the bottom is near, everything bad is already in the price" or "the structure is broken, sell the bounces".

Memory backs it up: almost every coin that fell had this picture before its next leg down. That is true. But it also had it before everything else.

There is a third layer of credibility. The shape is easy to describe in words and easy to program. Anything that can be formalised feels tested — even though pure noise formalises just as well.

How we tested it

We took a broad set of liquid coins and ran the condition over history: whenever the picture came together we marked the moment and looked at what happened over the next month and the next three. Then the important part: we compared that not against zero but against simply "take any coin on any day in the same period". If the picture means something, the result after it should differ from the result after a random day.

Separately we counted how often the shape occurs at all. If the condition holds on almost every coin, it is not a filter — it is a description of the market.

How it ended

There is no difference from the market. Over three months the result after the picture matches the result after a random entry in the same period — meaning the profit is entirely explained by the fact that the whole sector was falling at the time. Over one month the picture is actually worse than a random entry: selling right after a failed push means selling at a moment when price has just dropped and is inclined to bounce.

And the rare but huge case did not go away. Sharp rips up against a short position happened after this picture exactly as often as without it. The filter did not remove the main danger, it only created a feeling of selectivity: almost every coin in the set had the shape — it is the signature of an entire bear period, not a setup.

What this teaches

• You can call the direction correctly and still earn nothing beyond what the market itself pays. The question to test is not "was I right" but "is it more than without me".
• If the condition holds on most coins, it is a description of the background, not a signal. Count how often it fires across the set before drawing any conclusion about returns.
• A chart shape on its own carries almost nothing. What pays are mechanisms where somebody is forced to sell or buy: a forced exit, liquidations, the cost of holding a position.
• Every signal like this is tied to the period. In a set where everything was falling, they all look alike; in a turn, those same charts produce the sharpest rips up.
