The Diamond pattern (Diamond Top and Diamond Bottom) is one of the rarest yet most powerful reversal patterns in technical analysis, named for its uncanny resemblance to a perfectly cut rhombus diamond. Its defining structure is 'expand first, then contract' - the left half is a broadening megaphone, the right half is a symmetric triangle, and together they trace out a complete rhombus. Diamonds appear less often on Binance Futures than triangles, flags, or even head-and-shoulders (statistically about 1/3 the frequency of H&S), but when they form, win rate is high (~70%) and the resulting reversal often exceeds 80% of the prior trend leg. This guide ports the pattern to crypto futures with BTC and ETH data, covering the diamond's definition, 5 identification rules, volume signature, comparisons with wedge / H&S / broadening, entry and exit strategy, precise stop-loss and take-profit math, real Binance Futures examples, and common failure modes, ending with 10 high-frequency FAQs.

The Diamond Top / Diamond Bottom was first systematized by Edwards and Magee in Technical Analysis of Stock Trends and is one of the most distinctive yet least common reversal patterns in technical analysis. Its standard definition: price first goes through a phase of expanding amplitude (a broadening megaphone), followed by a phase of contracting amplitude (a symmetric triangle), the two halves together forming a rhombus diamond shape.
Core components:
On Binance Futures, diamonds typically appear in three contexts:
The diamond's core value is that it draws the entire arc from 'expanding disagreement' to 'converging consensus' on a single chart. When expansion gives way to contraction and contraction gives way to breakout, a trend-level reversal usually follows.
The diamond visualizes a two-stage evolution of market sentiment: first, disagreement intensifies (expansion); second, consensus consolidates (contraction); finally, the consensus direction breaks the equilibrium (breakout).
At the end of the prior trend, bulls and bears clash over future direction. Bulls add on strong fundamentals; bears short the technical top. Neither side yields, and every candle tries to set a new ceiling or floor. Volume surges erratically - each reversal comes with a sharp burst that doesn't last. This is the engine of a broadening megaphone.
The diamond's widest point coincides with peak market disagreement. Often there is a major catalyst - regulation, an ETF decision, a critical data print - and both sides put real money behind their convictions. This phase is the shortest in time but the most violent in motion - the most dangerous and most informative segment of the entire pattern.
The extreme volatility burns through both sides' ammunition. Bulls realize the ceiling won't break; bears realize the floor will hold. Both gradually drop their extreme positions and converge toward neutral. Amplitude shrinks rapidly, volume decays steadily, and the pattern transitions into a symmetric triangle. This is the diamond's most critical 'preparation phase' - consensus is forming silently, just one candle away from ignition.
When the contracting half nears its right apex, volume freezes, and both sides are exhausted, even a faint signal (a single high-volume candle, a piece of decisive news) can trigger a collective directional choice. The breakout direction is the new trend's direction. This is why diamond breakouts have such persistent follow-through - it isn't one side winning, it's the market making a collective decision after a long standoff.
A diamond requires 30-60 bars on the 4H chart (5-10 days) or longer, plus strict trendline conditions on both halves. This high bar filters out almost all coincidental price action. Backtest on Binance Futures 2023-2025 data: a confirmed daily diamond breakout produces a 10%+ reverse move within 3 weeks roughly 75% of the time on BTC/ETH - far above any single-candle signal. That 'rare but precise' quality is the diamond's highest virtue.

| Volume signature | Irregular surges left, steady decay right, breakout candle expansion | Same - irregular surges left, decay right, breakout expansion |

\/| Trendline | Pass criterion | Fail flag |
|---|---|---|
| Left-upper (rising highs) | Connects at least 2 rising highs, positive slope | Can't form a straight line → not broadening |
| Left-lower (falling lows) | Connects at least 2 falling lows, negative slope | Can't form a straight line → not broadening |
| Right-upper (falling highs) | Connects at least 2 falling highs, negative slope | Can't form a straight line → not symmetric triangle |
| Right-lower (rising lows) | Connects at least 2 rising lows, positive slope | Can't form a straight line → not symmetric triangle |
All 4 lines must enclose a closed rhombus. If only 3 of them work, you're looking at a different pattern.
A valid diamond should contain: 2 rising highs + 2 falling lows = 4 broadening pivots on the left half; 2 falling highs + 2 rising lows = 4 contracting pivots on the right half - 6-8 clear pivots in total. The two extremes at the widest center can act as shared pivots between the two halves.
| Width metric | Pass criterion | Note |
|---|---|---|
| Maximum width (center waist) | >= 15% of prior trend leg | Too narrow gets eaten by noise |
| Maximum width (center waist) | <= 50% of prior trend leg | Too wide isn't a reversal, may be a new trend |
| Left/right half width ratio | 0.7 - 1.4 | Severe asymmetry undermines the pattern |
| Timeframe | Valid bar count | Real time |
|---|---|---|
| 1H | 80-200 | 3-9 days |
| 4H | 30-60 | 5-10 days |
| Daily | 20-40 | 3 weeks - 2 months |
| Weekly | 10-20 | 2-5 months |
Use 4H and daily on Binance Futures. Anything below 1H is too noisy.
Whichever strategy you choose, the breakout candle must hit at least 1.5x the 20-bar average volume, and volume should stay elevated for 1-3 bars after the break. Otherwise it's likely a fakeout - exit immediately on a re-entry into the diamond.
Top traders demand that on a 4H diamond breakout, the daily already shows directional bias (e.g. EMA20/EMA60 cross), and 1H RSI isn't at an extreme. With three-timeframe alignment, win rate climbs to 85%+.
| Style | Stop location | Typical stop distance |
|---|---|---|
| Aggressive | 0.3% beyond the breakout candle's far edge | 1%-2% |
| Standard | 0.5% beyond the most recent counter-extreme inside the diamond | 2%-4% |
| Conservative | 1% beyond the diamond's opposite apex | 5%-8% |
Iron rule: stops must sit outside the diamond's interior. Once price re-enters the diamond by more than 15% of the pattern's width, the structure has failed - exit.
Three classic methods:
10,000 USDT account, 1% risk per trade (100 USDT). Entry 65,000 → stop 67,000 (Diamond Top short, 3.1% distance). Position size = 100 / 3.1% ≈ 3,225 USDT. With 3x leverage, margin used ≈ 1,075 USDT. TP2 at 60,500 gives ~4,500 USDT profit potential vs ~2,000 USDT risk - a 4.5:1 reward:risk, well above the 3:1 minimum.

Mnemonic: Diamond = 'fight first, agree later'; Wedge = 'silently compressing a spring'; H&S = 'three tests then exit'; Broadening = 'disagreement keeps growing, no conclusion'.
BTC rose from 38,000 to 73,500 (+93%), then from 2024-03-14 entered a ~45 bar 4H diamond. Left half (22 bars) shows a clear megaphone: highs 70,200 → 72,400 → 73,500 (rising), lows 67,800 → 65,500 → 63,800 (falling). Max width ~9,700 USD (73,500-63,800), about 27% of the 35,500 USD prior leg - well within range. Right half (23 bars) shows a symmetric triangle: highs 73,500 → 71,200 → 68,800 (falling), lows 63,800 → 65,800 → 67,200 (rising). On 03-30 the 46th 4H bar broke down through 67,800 on 2.6x average volume - a textbook Diamond Top. Standard short entry at 67,500, stop 71,500 (0.5% above right-half high, 5.9% distance). TP1 = 67,500 - 9,700 = 57,800 (hit at 56,800 five days later). TP2 = 67,500 - 19,400 = 48,100 (price hit 47,800 17 days later, trailing stop fired at 50,500). Reward:risk ~4.6:1.
ETH fell from 3,850 to 1,980 (-48%), then from 2025-08-25 entered a ~36 bar 4H diamond. Left half (18 bars): lows 2,050 → 1,995 → 1,980 (falling), highs 2,120 → 2,185 → 2,240 (rising). Max width ~260 USD, about 14% of the 1,870 USD prior leg - just barely passing. Right half (18 bars): highs 2,240 → 2,185 → 2,130 (falling), lows 1,980 → 2,030 → 2,080 (rising). On 09-12 the 37th 4H bar broke up through 2,150 on 1.9x average volume - a textbook Diamond Bottom. Standard long entry at 2,155, stop 1,990 (0.5% below right-half low, 7.7% distance). TP1 = 2,155 + 260 = 2,415 (hit 2,430 four days later). TP2 = 2,155 + 520 = 2,675 (price hit 2,680 11 days later, trailing stop fired at 2,580). Reward:risk ~3.5:1.
SOL fell from 245 to 152, then entered a chop zone that looked like a diamond. But the left half had only 3 pivots (rule requires at least 4) and the right-half volume failed to decay properly (only 70% of the left peak, well above the 50% maximum). Aggressive traders who scaled in long got run over: price popped to 167, stalled, then dropped back to 154 two days later, hitting stops at 148. About 12% loss. This is the most common diamond failure: too few pivots + insufficient volume decay. Strict adherence to the 5 rules in this guide would have filtered the trade out.
Chop is not a diamond. A real diamond requires you to draw 4 clean trendlines (left-upper, left-lower, right-upper, right-lower) that enclose a rhombus. If price just oscillates randomly with no straight-line geometry, it's a normal range with no diamond reversal energy.
Expansion only = broadening triangle (~50% win rate). Contraction only = wedge or symmetric triangle (direction unclear). You need both phases, in the order 'expand then contract', to call it a real diamond. The reverse order ('contract then expand') is a different and far less reliable structure.
Without U-shape or decay volume, the rhombus is probably coincidence. Around 35% of suspected diamonds on Binance Futures fail because volume doesn't cooperate. Breakout candle must hit at least 1.5x average; otherwise treat it as a fakeout.
Diamonds need at least 6 clear pivots. If you can only count 4-5, it's likely a broadening + triangle composite, not a true diamond. The more pivots (ideally 8), the more reliable the pattern.
On 1H or 15m there are too many 'rhombi' but most are noise. Diamond statistical edge is built on 4H and daily timeframes. For thin altcoins, restrict to daily charts only.
When a diamond fails (price re-enters by >15% of width), the prior trend often resumes rather than reverses. Holding without a stop gets you steam-rolled.
Depends on location. Diamond Top at the end of an uptrend is bearish; Diamond Bottom at the end of a downtrend is bullish.
Broadening has only the megaphone; diamond is 'expand then contract', a complete rhombus. Diamond win rate (~70%) is meaningfully higher than pure broadening (~50%).
Wedge is pure contraction (narrow cone), mainly continuation. Diamond expands first then contracts (rhombus), mainly reversal. The shapes are clearly different.
(1) End of clear trend; (2) 6-8 clear pivots; (3) U-shape or decay volume; (4) Width 15-50% of prior leg; (5) At least 30 bars on 4H or 20 on daily.
Standard: enter on the close of the breakout candle on >= 1.5x volume (~70% win rate, recommended). Conservative: wait for retest (~80%).
Standard: 0.5% beyond the most recent counter-extreme inside the diamond. Iron rule: stops must sit outside the diamond's interior.
Three methods: width projection (breakout ± diamond width), prior-trend projection (breakout ± 60%/100% of prior leg), Fibonacci extension (1.272/1.618/2.0). Scale out 40%/30%/30%.
Rarely. When the diamond appears mid-trend and the breakout direction matches the prior trend, it's a continuation pattern, ~60% win rate (vs ~70% for reversal diamonds).
About 55% of the time. If the retest pushes more than 15% of the diamond's width back inside, the pattern has failed.
Daily most reliable, 4H most opportunities, 1H and below too noisy. BTC/ETH daily diamond breakouts produce a 10%+ reverse move within 3 weeks ~75% of the time; 4H ~62%; 1H under 40%.
