Candles & Candle Closes

Candlestick charts are so universal that most traders never stop to ask what one actually records. That is a problem, because almost every bad habit further up the curriculum starts with reading candles as pictures rather than as data.

What a candle is

A candle compresses a period of trading into four numbers: open, high, low, close. Everything else — the body, the wick, the colour, the shape you recognise from a pattern chart — is a rendering of those four values.

That compression is enormous. A five-minute candle on NQ might contain thousands of trades. The candle keeps four of them and discards the sequence entirely.

Understanding what was thrown away is what stops you over-reading the result. The same candle shape can be produced by completely different auctions: a steady grind, a violent spike and reversal, or a quiet drift. The picture is identical. The intent behind it is not.

Why the close carries the most information

Of the four values, the close is the one that matters most, and the reason is structural rather than technical.

The high and the low are extremes — they record the furthest anyone was willing to transact, often on thin volume, sometimes on a single order. They are real prices, but they may represent very few participants.

The close is different. It is the price at which the period ended: the last point of agreement before the clock ran out. It is where positions were marked, where the next period begins, and — crucially — the value the largest number of other participants are also watching.

Which is why a level that has been closed beyond is meaningfully different from a level that has only been wicked through. A wick says price briefly traded there. A close says the market was still there when it mattered.

Wicks are not rejection by default

The standard reading of a long wick is rejection: price went there, was refused, came back. Sometimes that is exactly right.

But a long wick can also be a lack of participation. Thin liquidity lets price travel further on less volume, and it snaps back not because it was rejected but because there was nothing there in the first place. Overnight and around news, this is common.

The two situations look identical on a candlestick chart and mean opposite things. Distinguishing them requires knowing whether volume was actually present — which is one of the earliest reasons a candle alone is insufficient, and why this module sits at the start of a course rather than being the whole of it.

Timeframe changes the object

The same market produces different candles depending on the period you choose, and none of them is more correct than the others. A 1-minute close and a 1-hour close are both real, and they answer different questions.

What follows is that "the close" is only meaningful once you specify which close. A trader saying price closed below a level and a trader saying it did not may both be right on their own timeframe. Deciding which closes you act on — and being consistent about it — is a decision most traders never explicitly make.

Patterns are a shorthand, not a system

Named candlestick patterns are compressed descriptions of common shapes. They are useful vocabulary and they are not signals.

Any pattern you can define precisely enough to spot will occur dozens of times a session across timeframes, the large majority in places where it means nothing. The pattern is not the edge. Where it happens is.
