Bullish reversal pattern
Inverted Hammer: A Weaker Bullish Reversal
Sellers were present all session and still could not close price at the lows. That is a smaller claim than a hammer makes, which is why this pattern needs more from its confirmation.

An inverted hammer is a single candle with a small real body near the bottom of its range and a long upper shadow, appearing after a decline. It reads as a bullish reversal signal, and it is a weaker one than the hammer, because the session it describes ended with buyers handing back most of what they gained.
The shape is identical to a shooting star. What separates them is the trend that came before, and nothing else.
What the session actually looked like
Price opened near the lows after several sessions of decline. During the session buyers pushed it substantially higher, far enough to print a shadow several times the height of the body. Then sellers met that rally and price closed back near where it opened.
Read plainly, that is a mixed result. Buyers demonstrated they exist and can move price. Sellers demonstrated they are still in control of the close.
Compare it with a hammer, where price fell hard during the session and then closed back near the high. There, buyers finished in possession of the ground they took. Here they did not, and that is the whole of the difference in reliability between the two patterns.
What makes it bullish at all is the contrast with the sessions before it. In a steady downtrend, rallies of that size usually do not happen. A candle that travels a long way up before being pushed back is evidence that buyers are present in a way they recently were not, which is a change worth noticing even though the session ended badly for them.
The measurement test
Three ratios, all measured against the candle’s total high-to-low range.
| Component | Requirement | Why it matters |
|---|---|---|
| Upper shadow | ≥ 66% of total range | This is the rally. Without it there is no pattern. |
| Real body | ≤ 33% of total range | A large body is directional conviction, a different message. |
| Lower shadow | ≤ 10% of total range | A significant lower shadow makes this a spinning top. |
A candle passing all three after a downtrend is an inverted hammer. One passing two of the three is usually a spinning top, which carries no direction at all.
Body colour is a minor detail. A green body, closing above the open, is marginally better than a red one. Next to a shadow that long it is not the thing to decide on.
Why confirmation carries more weight here
Every single-candle reversal pattern needs confirmation. This one needs it more than most.
Confirmation is a later candle closing above the inverted hammer’s high. Until that happens, what you have is a failed intraday rally in a downtrend, which is an extremely common event and usually resolves lower.
That is not a reason to distrust the pattern. It is a description of what the pattern is: a hint that needs a second piece of evidence before it means anything. Entering on the inverted hammer’s own close buys a candle that closed near its low in a downtrend, and the price improvement rarely pays for the hit to the win rate.
Our guide to the hammer covers the same confirmation logic in more detail, and the reasoning applies with more force to this pattern than to that one.
Context does the heavy lifting
Shape is cheap, and in a downtrend candles with long upper shadows appear constantly. Location is what makes one of them worth acting on.
An inverted hammer earns attention when it forms after a sustained decline, at a level marked on the chart before the candle printed: a prior swing low, a support zone, the lower boundary of a range. Elevated volume helps, because it means real size changed hands during that rally rather than the move coming from an absence of sellers.
Ignore it mid-range. Ignore it against the higher-timeframe trend, as trade with the higher timeframe trend sets out. And ignore it when it is the third or fourth one on the same chart in a fortnight, because repeated failed rallies are telling you supply is heavy, not that a reversal is due.
Trading it
Entry. On a close above the inverted hammer’s high, or with a stop order a few ticks above that high so you are only filled if the market takes the level.
Stop. Below the inverted hammer’s low, with a small buffer. That low is the level sellers could not break during the session, and price trading back beneath it removes the reason for being in the trade.
Size. From the distance between entry and stop, not from how convincing the chart looks. Because entry sits above the high and the stop sits below the low, the risk on this pattern spans the candle’s entire range, which on a long-shadowed candle is wide. The position has to shrink accordingly, and the method is in how to set a stop loss using ATR and the position size calculator.
That last point is the one most often missed. A dramatic inverted hammer with a very long shadow looks like the strongest version of the pattern, and it carries the widest stop, which means the smallest position. The two pull against each other by design.
Where it fits against the other three
Four single-candle patterns share this family, and the differences are worth holding clearly, because three of them are distinguished by location rather than by shape.
| Pattern | Long shadow | Prior trend | Reads |
|---|---|---|---|
| Hammer | Lower | Downtrend | Bullish reversal, stronger |
| Inverted hammer | Upper | Downtrend | Bullish reversal, weaker |
| Hanging man | Lower | Uptrend | Bearish reversal |
| Shooting star | Upper | Uptrend | Bearish reversal |
Read down the table and a point emerges that is easy to miss: the hammer and the hanging man are the same candle, and so are the inverted hammer and the shooting star. Only the preceding trend separates each pair.
That has a practical consequence. A screener returning “inverted hammers” is returning candle shapes, and roughly half of what it finds will be shooting stars sitting in uptrends. The trend filter is not a refinement on top of the pattern, it is half of the definition, and the same applies when scanning for the hammer itself.
Common mistakes
Naming it without the trend. The same candle after an uptrend is a shooting star and means the opposite. The preceding trend is not context, it is part of the definition.
Treating it as equal to a hammer. It is the weaker of the two for a structural reason, not a stylistic one, and sizing it the same way ignores that.
Entering without confirmation. In a downtrend this is simply a failed rally until a later candle closes above its high.
Trading it mid-range. With no preceding downtrend there is no reversal available, because there is nothing to reverse.
Frequently asked questions
What is the difference between an inverted hammer and a hammer?
Which end the shadow is on. A hammer has a long lower shadow and a body near the top of its range. An inverted hammer has a long upper shadow and a body near the bottom. Both appear after a decline and both read bullish, but they describe different sessions and the hammer makes the stronger claim.
Is an inverted hammer the same as a shooting star?
The candle is identical. The preceding trend separates them. After a downtrend that shape is an inverted hammer and reads bullish; after an uptrend it is a shooting star and reads bearish. Without knowing what came before, the candle cannot be named.
How long does the upper shadow need to be?
At least twice the height of the real body, and preferably three times or more. The lower shadow should be small or absent, under roughly 10% of the candle's total range. A meaningful shadow on both sides makes it a spinning top instead.
Why is the inverted hammer considered less reliable than the hammer?
Because of where the close sits. A hammer closes near its high, so buyers held the gains they made. An inverted hammer closes near its low, so the rally within the session was given back. That is a weaker piece of evidence, and it is why confirmation matters more here.
Where does the stop go?
Below the low of the inverted hammer, with a small buffer. That low is the point the sellers could not push through. If price trades back under it, the premise of the trade has gone, whatever the pattern looked like.
