Ladder bottom candlestick pattern: rules, examples and data

A ladder bottom is a five-candle bullish reversal that looks like price walking down the rungs of a ladder and then stepping off. Three black candles each open and close lower than the one before. A fourth black candle follows, but this one leaves an upper shadow, a first sign that buyers pushed back during the session. Then a white candle opens above the fourth candle's body and closes above its high.

It is the more common cousin of several rare bottoming patterns. Where the Concealing baby swallow: a rare four-candle bottom explained needs perfectly shadowless candles and almost never appears, the ladder bottom's conditions are loose enough that it showed up 60 times on 42 of the 60 large US stocks and ETFs in our two-year test.

This guide covers the shape, the rules Finabase's scanner actually applies (which are looser than the books), what the pattern says about the balance of buyers and sellers, two real ladder bottoms from the same day in March 2026, and the data.

Anatomy of a ladder bottom

1. Three black candles in a staircase. Each opens below the previous open and closes below the previous close, like a milder version of three black crows.
2. A fourth black candle with an upper shadow. Price still closes lower, but during the session it traded noticeably above where it ended. Some descriptions compare this candle to an inverted hammer.
3. A white fifth candle that opens above the fourth body, which is a gap relative to that body, and closes above the fourth candle's high.
4. A decline before all of it. The pattern describes the end of a sell-off, so it needs one.

The exact rules Finabase uses

TA-Lib's CDLLADDERBOTTOM, run on daily bars, checks:

Where it is more permissive than the textbook:

• Body size is never checked. The three staircase candles can be small. The textbook picture has long black candles that show determined selling; TA-Lib accepts a gentle drift as long as opens and closes keep stepping lower.
• The upper shadow can be short. One tenth of an average day's range is a small amount. In the Alphabet example below, the fourth candle's upper shadow was $0.67 on a stock trading near $275, about 13% of that day's range.
• Candle 4 is not tied to candle 3. The code does not require it to open or close below the third candle.
• No prior trend. The source says the pattern matters in a downtrend and leaves that judgment to the user. In our sample, 66.1% of detections followed a ten-session decline, so a third did not.

Why buyers read it as a turn

The staircase shows sellers in control for three sessions, with each open lower than the last: nobody was willing to pay up overnight. The fourth session is the first to crack. Sellers still win the close, but the upper shadow shows that buyers lifted price during the day and were turned back.

Then the fifth session opens above the whole fourth body. Overnight demand has returned, and buyers keep the initiative all day to finish above the fourth candle's high. Anyone who shorted during the staircase is now looking at a stock above the last two sessions' prices. That forced buying from shorts covering is part of what gives the pattern its bullish reputation.

Confirmation

A ladder bottom ends with a strong white candle, so it already contains some confirmation of its own. Practitioners still look for more:

• The next close above the white candle's high. This is the rule in our study, and it made the clearest difference (see the table below).
• A higher low. If the next pullback holds above the low of the staircase, the bottom has been tested and defended.
• Broader context. Ladder bottoms often appear on days when the whole market rebounds. A pattern that forms on a stock rising against a weak market says more about that stock than one that rides a market-wide bounce.

One day, two outcomes: March 31, 2026

On March 31, 2026, TA-Lib found ladder bottoms on nine of our 60 symbols at once: Alphabet, Citigroup, Goldman Sachs, Home Depot, Microsoft, Morgan Stanley, Nike, Oracle and UPS. That is 15% of every ladder bottom in two years, printed on a single session in which the broad market rallied. Two of them show how differently the same signal can play out.

Alphabet (GOOGL). After a 7.5% slide over ten sessions, GOOGL's staircase ran from March 25 to March 27, with opens of $293.44, $287.91 and $277.28 and lower closes each day. March 30 was black with a small upper shadow. On March 31 the stock opened at $278.04, above the $276.42 open of that fourth candle, and closed at $287.56, well above its $277.09 high. The next session closed at $297.39, above the white candle's high, so the pattern was confirmed. Ten sessions after the ladder bottom, GOOGL was 17.2% higher.

Nike (NKE). Nike's ladder bottom was textbook in shape: three lower black candles from March 25 to March 27, a black March 30 with an upper shadow, and a white March 31 from $51.93 to $52.82, above the prior high of $52.19. It was never confirmed. The next morning NKE opened at $46.56, about 12% lower, and closed the day 15.5% down. Ten sessions later it was still 14.0% below the ladder bottom's close. No five-candle pattern can see a gap like that coming, and the unconfirmed signal would have kept a cautious trader out.

What the data says

We ran CDLLADDERBOTTOM over daily bars from October 30, 2024 to October 29, 2026 for 60 large US stocks and ETFs.

(One detection was too recent to measure, so the hit rate covers 59 cases.)

The raw pattern was close to a random day. A 54.2% hit rate and a five-session average near zero leave no edge to speak of.

Ten-session returns were stronger at +2.04%, but that average leans on a few large winners from rebound days like March 31, 2026, and many ladder bottoms in the sample share the same few dates.

Confirmation helped, on a small base. Requiring the next close above the white candle's high, and measuring from that close, lifted the five-session hit rate to 63.2%. With 19 cases, the margin of error is wide enough to swallow most of that gap.

Ladder bottom versus similar patterns

An educational outline

How a practitioner might approach a ladder bottom. It is not a recommendation to trade.

1. Check the decline. Measure the fall before the staircase, and check whether the whole market is bouncing the same day.
2. Wait for the confirmation close above the white candle's high.
3. Put the invalidation point at the staircase low. A close below the lowest low of candles 3 and 4 means the bottom has failed.
4. Size from that distance. Ladder bottoms often form after wide-ranging sessions, so the stop can be far away.

How Finabase shows ladder bottoms

• On charts, the Ladder Bottom study puts a marker on the white fifth candle of each detection on a symbol's daily chart.
• In the scanner, TA-Lib's result is always positive, so ladder bottoms only ever appear on the bullish candlestick list. Expect bursts: on a broad rebound day the list can fill with several names at once.
• On the Signals tab, the symbol page's Candlestick gauge (for example AAPL's) gives this pattern a Buy vote for eight bars after a detection. Each of the 61 patterns votes from its latest non-zero reading in that window, and the votes are combined as (buy − sell) / (buy + sell + min(neutral, max(buy, sell))), with Buy at 0.2 or more and Strong Buy at 0.6 or more. A ladder bottom vote was present on only 1.6% of stock-days in our sample.

Frequently asked questions

Is a ladder bottom bullish?

Yes. It is a bullish reversal pattern, and TA-Lib only defines the bullish form, so every detection Finabase shows is scored +100.

What is the bearish version of a ladder bottom?

Some sources describe a mirror-image "ladder top", but TA-Lib does not implement it, and Finabase does not scan for it.

Does the white candle have to gap up?

It has to open above the fourth candle's body, which is a gap relative to that body. It does not have to open above the fourth candle's high, so the shadows may overlap.

Why did so many ladder bottoms appear on March 31, 2026?

Several stocks had drifted lower in step during late March and then rallied together on the same day. Candlestick patterns respond to the market's mood as much as to any single stock, so they tend to cluster around broad turns.

Summary

The ladder bottom pictures a staircase of selling that cracks on its fourth step and then gives way to a strong white candle. Finabase detects it with TA-Lib's lenient five-candle test, always scores it bullish and leaves the downtrend check to you. On 60 US large-cap cases the raw signal was barely better than a random day, while the 19 confirmed cases did noticeably better on a sample too small and too clustered to trust fully. Alphabet and Nike on March 31, 2026 show both sides of the same signal: confirm it, know where it fails, and check whether the whole market is doing the same thing.
