A long lower wick with a small body on top — the hammer’s silhouette is easy to recognize. What’s harder is knowing what to do with it: buy right away, wait for the next candle or skip the situation altogether. The same shape even has a different name after a decline than after a rise. Let’s go through the hammer, the hanging man, the inverted hammer and the shooting star, and then build a specific practice scenario on intrade.bar. It will have separate rules for the shape, the confirmation, the expiry and when not to enter.
What a hammer candle looks like
A hammer has a small body in the upper part of its range, a lower wick noticeably longer than the body and a short upper wick or none at all. A common rule of thumb is that the lower wick should be at least twice as long as the body. This is a way to classify the shape, not numerical proof that a rise is more likely after it.
Take an open of 100, a close of 101, a high of 101.2 and a low of 97.8. The body is 1, the lower wick is 2.2 and the upper wick is 0.2. The silhouette fits the usual description. But to call the candle a hammer in context, you also need to see a preceding decline, rather than cut a nice-looking shape out of the middle of any chart.
It’s convenient to measure wicks from the edges of the body. The lower wick is the lower of the open and close minus the low. The upper wick is the high minus the higher of those two prices. That way the calculation stays correct for a candle of either color. If you always measure from the open, red and green candles end up with sizes that can’t be compared.
Hammer and hanging man: same shape, different position
After a decline, a candle with a small upper body and a long lower wick is traditionally called a hammer. After a rise, a similar silhouette is called a hanging man. In the first case, what draws attention is the rebound from the lower part of the range after a prior fall. In the second, it’s a noticeable move down within a structure that had been rising.
This doesn’t mean the name knows the future. It’s a short description of how the shape relates to the stretch before it. If you show just one candle, you can measure its body and wicks, but you can’t confidently choose its contextual name. For that, you need the history leading up to it.
A useful note reads like this: “small body on top, long lower wick, preceded by several lower highs and lower lows.” After that, the word “hammer” becomes a handy shorthand. If you start with the catchy name, it’s tempting to draw in the trend you need to fit the candle you like.
Inverted hammer and shooting star
An inverted hammer has a small body at the bottom and a long wick pointing up. This pattern is considered after a decline. A similar shape after a rise is called a shooting star. One rule applies to both pairs: the geometry and the preceding move are described separately.
A long upper wick tells you the price traded well above the body and finished the interval below its high. But a single candle can’t tell you the exact order of every move or what participants intended. A story about “buyers winning” is handy for explaining things, until it starts replacing the values you can actually observe.
Don’t lump regular and inverted hammers into one sample right away. They have different silhouettes and different movement within the range. Test each pattern separately first, with identically worded conditions. Combining them only makes sense as a next hypothesis described in advance, not as a way to add pretty examples.
How to tell whether there was a decline before the candle
Three red minutes can be part of a rising hour. So the phrase “after a decline” needs a timeframe. For manual analysis, look at the sequence of notable highs and lows; for repeatable research, write down an exact criterion and observation window.
In a practice test, you could, for example, require the close to have fallen over a chosen number of completed candles and a lower local low. This is one way to describe context, not a universal definition of a trend. What matters is not changing the window length after the subsequent move has become visible.
If the candle sits in the middle of an unclear range, you can leave it as “a candle with a long lower wick.” Not every silhouette needs a trading purpose. Renaming noise as a pattern adds no data, but it easily creates the feeling that such a “signal” can’t be missed.
Check the interval boundaries as well. A five-minute candle can combine a drop and a rebound into a single hammer; if the five-minute windows start at a different time, the same moves will be split across two candles. To compare terminals, you need the same source, timeframe and time boundaries. Otherwise, the argument about proportions begins before the input data has been aligned.
Color and size: what really changes
A hammer can close slightly above or slightly below its open. The color reflects that difference, but it doesn’t cancel out the long lower wick. With a small body, a few price ticks change the color while most of the geometry stays the same. That’s why a rule like “green means buy, red means sell” loses an important part of the context.
Compare the full range of the shape with the neighboring candles. A wick three bodies long can be tiny on the market’s scale if the body itself is almost zero. Another candle with the same ratio can be huge. The proportion is the same, but the possible late entry and the nature of the subsequent swings differ.
Near the doji boundary, the wick-to-body ratio becomes very large simply because the denominator is small. That’s not an infinitely stronger signal. In your practice rules, specify how to classify a near-zero body, so you don’t count the same case as a hammer one time and a dragonfly the next, depending on the outcome.
Confirmation needs an exact definition
“I’ll enter after confirmation” isn’t a rule yet. It could mean the next green candle, a close above the hammer’s high or a breakout from a local range. Pick one observable event. Then it will be clear when it has happened and when there’s no point waiting for it any longer.
Confirmation changes the entry price. If the price rose sharply after the hammer, a later decision is made on new terms. You can’t use that rise as an argument for entering and at the same time count the profit from the previous candle’s low. That trick makes the story convincing, but it can’t be reproduced in the terminal.
An extra condition can reduce the number of signals, but that alone doesn’t prove the results improve. Compare the variants on full samples with their own actual entries. A few nice confirmations show that a scenario is possible, not that it holds up.
A practice hammer test on intrade.bar
On the intrade.bar demo, choose an available currency pair and a five-minute TradingView chart. Before you start looking, write down the shape criteria: a small body in the upper part, a lower wick at least two bodies long, a short upper wick. Add one definition of a preceding decline and a consistent way to exclude near-zero bodies.
Wait for the candidate to close. For this exercise, confirmation will be the next five-minute candle closing above the hammer’s high. If that exact next candle doesn’t meet the condition, the case ends without an entry. Don’t wait indefinitely for a convenient confirmation of what is by then a different situation.
If the condition is met, you can open a practice Call trade with a fixed amount chosen in advance. Separately, fix a test expiry, for example fifteen minutes in Sprint, if it’s available. This is a parameter of the hypothesis in its own right, not a property of the hammer. Check the exact expiry and the payout in the trade form before opening.
Save the actual entry price, the time, the payout and the trade result. On intrade.bar, the profit on a winning outcome is known from the terms before the trade, so it’s easy to separate testing the candlestick pattern from the money arithmetic. If the payout changes from case to case, account for that in the final calculation, even with the same amount.
When the entry is cancelled
Skip the candle if its shape is still changing, the context doesn’t match the rule or the confirmation came after the allowed interval. Record lateness separately: if the planned moment of entry was missed, a trade at the new price no longer repeats the original condition. An imaginary trade on history is no substitute for a real one.
For an oversized confirming candle, you can set a distance filter in advance, for example not entering if the price has moved away from the hammer’s close by more than its full range. That filter also needs testing; you can’t add it only to future losing cases. Write it down before the series begins or test it as a separate version.
The amount should fit your personal budget, taking open trades into account. intrade.bar’s optional risk management can additionally stop new entries once the daily limit you’ve set is reached. But it doesn’t determine the quality of a hammer, and it doesn’t justify a bigger amount just because the wick looks impressive.
Expiry is not the same as a nice continuation on the chart
After a hammer, the price may dip first and then rise noticeably. On a wide view, this will look like a correctly spotted reversal, but a short contract can close during the initial dip. A digital trade needs a result at its exact expiry relative to the actual entry.
Don’t change the measurement horizon for each example. If you’ve chosen fifteen minutes, test fifteen minutes whether the rise comes early or late. Picking the best moment from the future tests your ability to tell a nice story, not a rule you could have used in advance.
The timeframe, the confirmation delay and the contract’s expiry are three separate values. Record them separately. Then you can see which change affected the result, instead of reaching a vague conclusion like “the hammer isn’t working today.” A different expiry will require its own test.
What to record after a series of observations
Keep every qualifying case, including the losing and cancelled ones. In separate notes, record the geometry, the context, the confirmation and the reason for skipping. In intrade.bar statistics, look at assets and expiries, and match the CSV against your notes: the built-in history doesn’t classify candlestick patterns for you.
Check whether the selection can be repeated without knowing the future. Then compare the regular hammer with the inverted one as separate groups, without changing expiries and amounts at the same time. Different market stretches matter too: one good day doesn’t describe how a pattern behaves in all conditions.
Start by learning to recognize the shape and with one consistent demo test. A good skill to take away from this article is being able to explain why a particular candle fit the rule and why another was skipped. Then the hammer stops being a promise of a reversal and becomes part of a clear decision-making process.
Questions and answers
What’s the difference between a hammer and a hanging man?
The shape is similar: a small body on top and a long lower wick. A hammer is considered after a decline, a hanging man after a rise. Without the preceding stretch, you can determine the geometry, but not the contextual name.
Does an inverted hammer mean a fall?
Not automatically. That’s the name for a shape with a long upper wick after a decline; a similar silhouette after a rise is a shooting star. The subsequent direction requires separate conditions and testing.
Must the wick be exactly twice as long as the body?
A two-to-one ratio is a common rule of thumb. For research, it’s more important to choose a definition in advance and apply it consistently. A small change in proportion doesn’t create a sudden jump in reliability.
Can I trade a hammer on intrade.bar without confirmation?
You can test that hypothesis separately on the demo, setting the actual entry moment, expiry and risk. But the results of the version with a later confirmation can’t be credited to an early entry. These are different rules with different prices.
