Inverted Hammer: The Name Depends on Context
An inverted hammer is a candle with a small body at the bottom of its range and a long upper wick, appearing after a decline. The same shape after an advance is called a shooting star and read bearishly, which means the position on the chart supplies all of the meaning.

How it works
An inverted hammer has a small body at the bottom of its range and a long wick above it. Price rose during the session and gave all of it back before the close.
The threshold is the same as its mirror image: an upper wick at least twice the body, with little or no wick below. And it is required to appear after a decline, which is the entire difference between this and a shooting star.
Two names, one shape, opposite meanings. After a fall it is an inverted hammer and read as bullish; after a rise it is a shooting star and read as bearish. Nothing about the candle changes.
That should be the headline fact about single-candle patterns, and it usually is not. If the same four prices support opposite conclusions depending on their neighbors, then the neighbors are carrying the information and the candle is a label for where you are looking.
The story it is asked to tell
The bullish reading is that buyers attempted a rally. Even though the attempt failed and price closed back at the lows, the argument goes, the attempt itself shows demand appearing after a long decline.
The bearish reading of the identical bar is that a rally was rejected. Sellers were waiting, price could not hold the highs, and the failure is the signal.
Both readings are available for the same picture, which is worth sitting with. It is not that one is correct. It is that a shape which supports either interpretation supports neither on its own, and needs a separate argument — structure, level, participation — to mean anything.
Volume is the separate argument most often available. A failed rally on heavy participation and a failed rally on almost none are genuinely different events, and the volume histogram is the only part of the chart that can tell them apart.
In practice: what the count says
Apply the definition mechanically to a daily chart and the shape turns up far more often than textbook examples suggest, because a two-to-one wick rule is easy to satisfy on a small body.
Most people then check whether the next bar closed higher, and stop there.
The comparison they skip is any day at all. On the S&P 500 from 1950 to 2026, 53.1% of trading days closed up, so a candle followed by a higher close 53% of the time on that index has predicted nothing, and a few points above that on a few dozen events is well inside what chance produces.
Read those two figures together every time you see a pattern statistic. A number without an occurrence count and a base rate beside it is not a measurement, and the majority of published candlestick statistics supply neither.
The shape is an artifact of where you cut the bars. A daily inverted hammer contains, on a lower timeframe, a rally and a decline with their own structure. Change the bar length and the pattern appears or vanishes without the market doing anything.
A gap up that fades all session draws a perfect inverted hammer, and there was no attempted rally in it at all — the high was set at the open by the reopening price, not by buyers pushing.
Every one traded pays a round trip in spread and commission. On a $10,000 account risking $100 a trade, a $10 round-trip cost is a tenth of the risk on every attempt, and a few-point edge on a coin flip does not survive many of those.
And the order book holds no record of the rejection. By the time the bar closes, the orders that were there at the high are gone — filled, pulled or expired. The wick is what happened, not what remains.
What an inverted hammer is not
It is not a signal on its own. It is a shape whose meaning is supplied entirely by its position.
It is not a shooting star, and it is the same candle. The distinction lives in the bars before it, which is a fact about naming rather than about markets.
It is not stronger when green. Some sources say a green body strengthens the bullish read. The body in an inverted hammer is small by definition, so the difference between green and red here is often a single tick.
And it is not a level. The high of the wick is a price price reached and left. It is not resistance until price has been turned away there more than once.
How this connects
A small body with a long upper wick, which makes it geometrically the same bar as a shooting star - the difference is only what came before it.
That is worth pausing on. Two named patterns with identical shapes, distinguished entirely by context, is a sign the context is doing the work.
It sits in the candlestick patterns vocabulary, so the timeframe and session boundary decide whether the bar exists in that form at all.
Reversals are the attached claim, and a single bar cannot contain a statement about the next one.
And the hammer candle is its vertical mirror - same body, wick below instead of above.
When it fails
In a range the ceiling prints them on repeat. Price approaches the top, turns, closes near the bottom of its bar: that is the definition being satisfied by ordinary oscillation. The shape appears most often exactly where it explains least.
The second failure is the missing context check. A screener flags the shape; only the bars before it decide whether it is an inverted hammer, a shooting star, or nothing at all. A great many published “patterns” are the shape with the context clause quietly dropped.
A third is trading the failed rally as a bullish entry. The narrative — buyers tried — is doing a lot of work to reframe a session that closed at its lows. If you would not buy a bar that closed at its lows without the wick, the wick is not much of an argument.
A fourth is the small-body problem. On a thin instrument or a quiet session, the body can be one or two ticks, which makes the two-to-one wick ratio trivially satisfied. The pattern then measures illiquidity rather than rejection.
And a fifth is stacking it with other candle patterns. Two candle signals on adjacent bars are two readings of the same short stretch of price, which the confluence page treats as the standard way traders manufacture confidence without adding evidence.
The original data
The base rate any bullish candle has to beat is large: 53.1% of S&P 500 trading days from 1950 to 2026 closed higher than the day before. A bullish reading of this candle that is right about half the time on that index is matching the market’s own drift, not reading buyers.
Run the same count for the hammer and watch for the likely problem. If two patterns with opposite shapes both land a few points above the up-day rate, on samples of a few dozen each, the honest conclusion is that neither number is measuring the pattern, and no amount of additional charts of textbook examples changes that.

Hammer candle is the mirror shape and carries the same counting exercise. Candlestick patterns covers the vocabulary these names belong to. And reversals is the event both patterns claim to mark.
I do not trust single-candle names. The same picture is bullish or bearish depending on what sits to the left of it, which means the picture is not what is doing the work. Read the context directly rather than through a shape vocabulary.
