Entropy borrows from information theory to ask how much of price action is genuinely structured and how much is closer to a coin toss. A low figure describes a market with memory, where what happened today carries something about tomorrow.

A high figure describes the opposite, and it is expensive. Near-random conditions punish any system that needs a trend to survive, and the punishment arrives as a run of small losses rather than as one obvious mistake.

What it actually measures

The four bands describe how much exploitable pattern is present, running from a market that is moving with memory through to one behaving essentially at random. Nowhere in that scale is there a claim about direction.

The most useful reading is which band the market has settled into rather than the exact figure. Systems that need structure to survive are worth running in some of these conditions and worth switching off in others.

What gets plotted is deliberately calmed, which is what stops the chart, the tooltip and the summary quoting three different numbers for the same session at the right-hand edge.

Low entropy tells you nothing about which way

The temptation with an ordered reading is to hear it as encouraging, because order sounds like the opposite of trouble. It is nothing of the sort. A market falling steadily and predictably is exactly as ordered as one rising steadily and predictably.

What the reading grants is permission for a method rather than confidence in a destination. Trend and momentum systems work in either direction, and knowing that the market currently has memory is worth a great deal without hinting at what the memory contains.

What it does not tell you

The bands are boundaries somebody drew. A market sitting close to one will cross back and forth without meaningfully changing behaviour, and the label will look decisive when the underlying condition has not moved.

Structure being present is not the same as structure being profitable. A market can have plenty of memory and still hand out false starts, so the ordered end promises better odds rather than good outcomes.

Everything here looks backwards. The figure describes the stretch that has just finished, and a regime is perfectly capable of changing character before the reading has finished acknowledging the last one.

How to read it

Random. Returns are close to a coin toss. Very little pattern is present and directional signals amount to noise.

Choppy. Pattern is breaking down and anything directional is being cut about in both directions.

Trending. Enough pattern is present for trend and momentum to earn something, false starts included.

Ordered. The market is moving with memory, and this is where systems built on persistence do their best work.

Entropy is kept on the Volatility dashboard, in company with Return Distribution, Waves and Volatility Directional Bias.

Common questions

What does this reading actually measure?

How ordered or close to a coin toss price action currently is. A low figure means the market is moving with memory; a high one means it is behaving almost at random, which is punishing for anything that needs a trend.

What separates the four bands?

How much exploitable pattern is present, from a market with genuine memory through to one that is effectively noise. None of the four says anything whatever about direction.

What is the right response to a random regime?

Stop believing directional signals. There is almost no pattern to work with, and the usual bill for ignoring that arrives as a steady drip of modest losses from strategies built on persistence.

Is an ordered reading bullish?

No. Order helps strategies built on persistence whichever way the market is going. It reports that memory exists and stays entirely silent about what the memory holds.

Why is the plotted line calmer than the raw figure?

Because everything on screen draws from the same calmed series. That is what stops the chart, the tooltip and the summary quoting three different numbers for the same session.
