Matching Low Pattern: When Two Red Candles Close at the Same Price

Some candlestick setups shout. The matching low pattern barely clears its throat. Two red candles, a falling stock, and both days end at exactly the same closing price. That’s it. No long tail, no dramatic gap. Yet that quiet repeat of a closing level tells you something about who showed up at the end of each session, and it is worth knowing how to read it properly.

We’ll cover what the pattern is, what the textbook says it means, what testing on real price data says it actually does (the two don’t agree), and how to trade it on an Indian stock chart with a clear entry, stop and position size.

What the matching low pattern looks like

The pattern needs three things, in this order:

1. A downtrend going in. Price has been falling for a while. Without that, two equal closes are just noise.
2. A bearish first candle. A black (red) candle, normally with a long body, that keeps the decline going.
3. A second bearish candle that closes at the same price as the first. Also black, and its close matches the first day’s close.

The Candlesticker pattern reference describes it as two black candlesticks with equal closes during a downtrend, with the first one normal or long and the second closing exactly at the first day’s close. Thomas Bulkowski’s matching low page on ThePatternSite adds a useful detail: the first candle should have a tall body, but the second one need not.

It is the close that matches, not the low

This trips people up because of the name. Bulkowski is blunt about it: the closing price is what matches, not the low price. The two candles can have different intraday lows, different opens, different wicks. What has to line up is where each session ended. If it’s the lows that match instead, you’re looking at something closer to a tweezer bottom, which we cover in our guide to tweezer tops and bottoms.

The story the two candles tell

Think about the sellers. On day one they push the stock down hard and it closes near the bottom of a long red body. On day two the stock still closes below where it opened, so the bears won the session again. But they couldn’t get the close any lower than yesterday’s.

Candlesticker sketches the trading behaviour like this: after the strong black candle on day one, the market opens higher on day two, trades higher still, but ends up back at the previous close. Its reading is that this shows short-term support and starts to worry the bears, and that the identical closes, rather than the intraday action, carry the message.

Two sessions, two sets of sellers, one closing price. The question the pattern asks is whether that price is a floor or just a pause on the way down.

That’s the traditional view. The trouble is that a pause on the way down looks exactly the same on day two. You only learn which one it was after the pattern completes.

Theory versus testing: the 61% problem

Here is where it gets interesting. The matching low is classed as a bullish reversal. The TA-Lib technical analysis library, used by a lot of screeners and backtesting tools, treats its CDLMATCHINGLOW function as a bullish signal and only ever returns +100 when it finds one.

Bulkowski tested the pattern and found something else. On his page, the theoretical performance is listed as bullish reversal, but the tested performance is a bearish continuation 61% of the time. In plain words: in 61% of the cases he measured, price pushed through that “support” and kept falling, rather than turning up.

But don’t throw the pattern out yet. The same page lists these figures (all ranks are out of 103 candlestick patterns, where 1 is best):

• Overall performance rank: 8. That’s high, and it reflects how well price trends after the breakout, whichever way it goes.
• Frequency rank: 58, roughly the middle of the list. You’ll find it in a price history, but not every week.
• Best percentage meeting price target: 69%, in a bull market with an upward breakout.
• Best average move in 10 days: 7.15%, in a bear market with an upward breakout, which ranks 13th on 10-day performance.

Bulkowski also notes that the pattern does best after an upward breakout. Since price is falling into the pattern, that means the best results come when it actually works as a reversal, which is the minority case. So the honest summary is this: the matching low is more likely to break down than up, but when it does break up, the move tends to be worth having.

That combination tells us how to trade it. You don’t buy the pattern. You wait for it to prove which way it is going.

How to trade the matching low pattern

Step 1: Confirm before you act

Candlesticker sets the confirmation level at the midpoint of the first black candle’s body. Price should cross above that level before you treat the pattern as a buy signal. This filter matters because it throws out most of the cases that turn into continuations, since those never get back up to the midpoint.

Step 2: Place the stop

The same reference puts the stop-loss at the lower of the two candles’ lows. If price closes below that level after you’ve entered, the support idea has failed and there’s no reason to stay.

Step 3: Check where the pattern sits

Context does a lot of the work here. Bulkowski lists three tips from his Encyclopedia of Candlestick Charts:

• Matching lows that appear within a third of the yearly low perform best.
• Matching lows within a third of the yearly low also act as continuations most often.
• The setup he favours is trading the matching low as part of a downward retracement inside a bigger upward trend.

The first two look like they contradict each other, but they don’t. Near the yearly low, the pattern breaks down more often, and when it does break up, the moves are larger. That’s exactly why confirmation matters more there, not less.

The third tip is the one we like most. A stock in a healthy uptrend pulls back for a few days, prints two red candles closing at the same level, then pushes back above the first candle’s midpoint. Now the pattern is lining up with the bigger trend instead of fighting it. If you’re not sure how to judge the bigger trend, our technical analysis guide for Indian stocks walks through the basics.

Don’t buy the pattern. Buy the confirmation, and only when the bigger trend is already on your side.

Worked example: a hypothetical trade

The figures below are made up to show the arithmetic. They are not from any real stock.

Say a stock has been sliding for two weeks. Its 52-week range is ₹400 to ₹700.

• Day 1: opens ₹520, low ₹487, closes ₹490. A black candle with a ₹30 body.
• Day 2: opens ₹497, high ₹500, low ₹484, closes ₹490. Another black candle, closing at exactly the same ₹490.

That’s a matching low: downtrend, long black first candle, second black candle with an identical close. The lows are different (₹487 and ₹484), which doesn’t matter.

Where does it sit in the yearly range? The range is ₹700 minus ₹400, or ₹300. A third of that is ₹100, so the bottom third runs from ₹400 to ₹500. At ₹490, the pattern is inside the bottom third. Per Bulkowski’s tips, that means bigger potential if it works, but a higher chance it doesn’t.

Confirmation level: the midpoint of the first black body is (₹520 + ₹490) ÷ 2 = ₹505. We do nothing until price trades above ₹505.

Stop-loss: the lower of the two lows is ₹484.

Entry and risk per share: suppose day 3 rallies and we buy at ₹506, just above confirmation. Risk per share is ₹506 minus ₹484, which is ₹22.

Position size: with a ₹5,00,000 trading account and a rule of risking 1% per trade, the maximum loss is ₹5,000. Dividing ₹5,000 by ₹22 gives 227.27, so we’d buy 227 shares. That’s a position worth 227 × ₹506 = ₹1,14,862, and if the stop is hit cleanly the loss is 227 × ₹22 = ₹4,994.

The other outcome: now suppose day 3 doesn’t rally. Instead it opens ₹488 and closes ₹476, below both lows. The ₹490 “support” is gone, price never touched ₹505, and we never entered. That’s the 61% continuation case, and the confirmation rule just kept us out of it at zero cost.

Using a screener to find it

If you scan for this pattern with software, know what the scan is really checking. According to the TA-Lib documentation, its matching low function looks for two consecutive black candles whose closes are equal within a tolerance. It checks no shadow, body-size or gap conditions, and the bullish reading assumes a prior downtrend that the function itself does not verify.

So a raw scan will throw up plenty of junk: two small red candles in a sideways market, or a pair halfway through a rally pullback with no real trend behind them. Use the scan to build a shortlist, then check each chart by eye for a genuine downtrend and a long first candle.

Also, “equal” is a judgement call on Indian stocks. A ₹2,500 stock that closes ₹2,481.10 and ₹2,481.35 is, for practical purposes, a match. Most screeners handle this with a tolerance setting, and it is worth knowing what yours uses.

Mistakes we see traders make

• Buying on day two. The pattern isn’t complete until you know which way it breaks. Given the 61% continuation figure, an early buy is betting on the less likely outcome.
• Confusing matching closes with matching lows. Equal lows point to a different pattern. Check the closing prices.
• Ignoring the bigger trend. A matching low inside a long-term downtrend is a much weaker setup than one inside a pullback in an uptrend.
• Skipping the stop. If price closes below the lower of the two lows, the idea is dead. Exit and move on.
• Trading it alone. Look for agreement: a bounce off a known support level, a pickup in volume on the breakout day, or another reversal candle nearby such as a hammer or a harami cross.

The matching low pattern in one paragraph

The matching low pattern is two black candles in a downtrend that close at the same price. Tradition calls it a bullish reversal. Bulkowski’s testing says it continues lower 61% of the time, yet it still ranks 8th of 103 patterns for overall performance because the upside breakouts, when they come, travel well. Treat it as a question, not an answer. Wait for price to clear the midpoint of the first candle’s body, keep a stop under the lower of the two lows, size the trade so that stop costs you a fixed slice of your capital, and favour the setups that show up as a pullback inside a bigger uptrend.
