Tweezer Tops and Bottoms: What 85 SPY Cases Showed
A tweezer top is a two-candle pattern in which consecutive sessions reach the same high after a rise, the first closing up and the second closing down. A tweezer bottom is the mirror, two matching lows after a decline, and both are read as a level the market tested twice and failed to break.
Two candles touch the same price and turn away. The pair looks like the two prongs of a set of tweezers, and it is read as a ceiling or floor the market tested twice in a row. This page pins down what “the same price” means, walks through an exact tie on SPY in January 2026, and counts every case on SPY since 1993 and on five large caps since 2000.
How it forms
A tweezer top needs a rise and two sessions that stall at one price. The first day closes up and reaches a high. The second day climbs back to that high, fails to get past it, and closes down. The matching highs are the prongs.
A tweezer bottom is the same picture upside down. After a fall, a red day sets a low, the next day comes back to that low, holds it, and closes up.
The reading is about a level, not a candle shape. The bodies can be any size and the shadows any length. What carries the idea is that buyers twice pushed to one price and twice gave way, which is the two-day version of a double top.
The version counted here adds a color change. An up day followed by a down day for a top, and the reverse for a bottom. Without it, any two days that happen to share a high would qualify.
How close counts as matching
The match width has to be set in numbers, because it decides the count. Two highs can be equal to the cent, a few cents apart, or a few dollars apart on a high-priced stock. The rule used here: the two highs (or lows) are within 0.05% of the first day’s high (or low), about $0.38 on a $760 SPY.
Exact ties are rare, and rarer now than they were. SPY priced its bars in fractions of a dollar in this file until 26 January 2001, and a coarse price grid makes equal highs common. From 1 February 1993 to 26 January 2001, 46 of 2,018 back-to-back SPY sessions had exactly equal highs, 2.3%. From 29 January 2001 through 2009 it was 18 of 2,245 (0.8%), in the 2010s 8 of 2,516 (0.3%), and since 2020, 2 of 1,692 (0.1%).
A percentage match stays steadier. Within 0.05%, the share of back-to-back sessions with matching highs was 6.5%, 7.3%, 9.1% and 5.9% across the same four eras. That is why a count built on exact ties mostly measures the tick size, and why every price here is compared unrounded: rounding the old fractions to decimals would split real ties or create false ones.
The full rule used here
The full rule, written out. Tweezer top: highs within 0.05%, day 1 closes above its open, day 2 closes below its open, the higher of the two highs is the highest high of the 20 sessions ending on day 2, and the close before day 1 is above the close 10 sessions before that. Bottom: the mirror with lows, a red day then a green day, a 20-session low and a falling close. The outcome is the close five sessions after day 2 against day 2’s close.
A worked example
SPY printed an exact tweezer top on 12 and 13 January 2026. On Monday 12 January it opened at $690.68, reached $696.09 and closed at $695.16, a green day. On Tuesday 13 January it opened at $695.49, reached $696.09 again, and closed at $693.77, a red day. The two highs were equal to the cent.
The context rules held. $696.09 was the highest high of the 20 sessions from 15 December 2025 to 13 January. The close on 9 January, $694.07, was above the $690.38 close of 24 December, so prices had been rising.
This one was followed by the drop it is read for. On 20 January SPY closed at $677.58, and five sessions after the pattern, on 21 January, it closed at $685.40, 1.21% below the $693.77 close. It was one of only two SPY sessions since 2020 whose high exactly matched the day before’s.
The original data
From 1993 to 2026, 70 SPY tweezer tops and 15 tweezer bottoms met the full rule. Without the trend and 20-session rules, the matching-and-color shape alone appeared 218 times at highs and 143 times at lows.
Tops were followed by a lower close less often than comparable days were. 28 of the 70 closed lower five sessions later, 40.0%, with a median change of +0.23%. On all 1,638 SPY days at a 20-session high after a rise, 717 closed lower five sessions later, 43.8%. The gap is small and points the wrong way for the bearish reading; an exact binomial test gives p = 0.549, well within chance.
Bottoms were too few to judge. 5 of the 15 closed higher five sessions later, 33.3%, against 401 of 665 comparable days, 60.3% (p = 0.061, not clear of chance). Fifteen cases can swing several points on one or two sessions.
The large caps leaned the other way on tops. Across AAPL, MSFT, JPM, XOM and KO from 2000, 68 of 133 tweezer tops closed lower five sessions later, 51.1%, against 45.1% of 4,945 comparable days (p = 0.191). 25 of 54 bottoms closed higher, 46.3%, against 56.5% of 2,920 (p = 0.134). Neither gap clears chance, and the SPY and large-cap tops disagree on direction. Every case is in the tweezer events file.
The match width changed the count far more than the result. With exact ties only, SPY had 7 tweezer tops and 1 bottom; at 0.05%, 70 and 15; at 0.10%, 161 tops and 29 bottoms. The share of tops followed by a lower close was 42.9%, 40.0% and 42.9%.
When it fails
The level breaks on the next push. Two equal highs mark where sellers showed up twice, not where they will show up a third time. On SPY, 42 of the 70 tops closed higher or level five sessions later rather than lower.
The match is too loose. At 0.10%, a pair of highs about $0.76 apart on a $760 SPY counts as matching. Widen the tolerance and the pattern stops describing a precise level and starts describing any two days near a high.
The bottoms are thin. With 15 SPY cases, one or two sessions move the share by several points, and the 33.3% figure is as likely to reflect the handful of dates as anything about the shape.
The exact version depends on the tick. A rule that demands equal-to-the-cent highs finds fewer cases every decade as prices rise and the price grid gets finer. The 2 exact matches since 2020 are too few to test anything.

The double top page covers the same tested-twice idea spread over weeks, where the peaks are further apart and the count behaves differently. Support and resistance explains why a price that stops a move once gets watched the next time. And the candlestick patterns overview puts the tweezer beside the other two-candle formations, including the harami and the bearish engulfing.
Treat matching highs as a level worth marking, not as a sell signal. Before I act on one, I check how close the two highs really are in cents, because a loose match turns almost any pair of days at a high into a tweezer.
