SUI Daily Pulse Aug 18, 2026: Flush Under $0.65

Where We Left It — Two for Two on the Channel Breakdown

Since yesterday's call, SUI dropped another 4.1%, sliding from around $0.675 down to roughly $0.65. Yesterday's short thesis — entry near $0.68, stop at $0.685 — hit its $0.66 target clean. That's two for two now on this channel breakdown thesis, and the trend that kicked off this Daily Pulse series is still doing exactly what it said it would do.

As of writing, SUI is changing hands around $0.65–$0.68 depending on the venue, down roughly 1.6%–4% on the day, with intraday lows near $0.646 and highs near $0.68 on major exchanges. Yahoo Finance data pegs the pair at $0.6734, down 1.61%, while Investing.com shows a slightly higher print of $0.6785 against a previous close of $0.6829 — the spread between venues itself is a tell we'll come back to later.

The Setup: Bearish Below the Mid-Sixties

SUI is trading around $0.65 right now, down over four percent on the day after sweeping through last week's support. Structure on both the fifteen-minute and four-hour charts is still making lower highs inside a descending channel. Momentum is neutral-to-soft — not oversold — which means there's room left to fall before this gets stretched.

Bias stays bearish below the mid-sixties unless buyers reclaim and hold that broken structure. In plain terms: the trend that started this pulse series is still intact, and nothing on the tape today has flipped it.

15-Minute Intraday — The Flush and the Fade

Zoom into today's session and you can see exactly where the pain happened — a single 15-minute candle wicked from around $0.67 down through $0.60 before buyers stepped back in. Since then, SUI's been chopping sideways right at the $0.65 mark, pinned under a descending trendline.

That wick is a liquidity grab, not a reversal signal yet — the structure above is still lower highs, lower lows. In plain terms: SUI crashed fast then went flat, and the trend is still pointing down.

4-Hour Structure — Channel Breakdown Confirmed

The four-hour view is the real story of the day. SUI had been grinding inside a tight descending channel since around August 9, and today it broke straight through the bottom of that channel on the heaviest volume bar we've seen in over two weeks. That's not a random wick — that's structural.

Until price reclaims back above roughly $0.68, this breakdown stays confirmed and the path of least resistance points lower. In plain terms: the price broke down through its trend channel on heavy volume today.

Short-Term Daily — Boxed In Between Two Walls

Pulling back to the daily chart, SUI's summer story is simple — a spike to $1.42 back in May, then a long, grinding bleed all the way back down. We're now testing the lower boundary of that multi-week range, with the $0.635 zone as the next real shelf of support.

Everything above that, back toward $0.70, is now acting as resistance instead of a floor. In plain terms: SUI gave back its summer bounce and sits near this range's bottom.

RSI (14) — Neutral, Not Oversold Yet

The daily RSI sits at 34 right now — that's the 14-period reading, and it's telling us momentum is weak but not yet exhausted. Thirty is the line most traders watch for oversold, and we're still six points above it.

No divergence has shown up yet either, meaning price and momentum are falling together, in sync. That's a sign this move could still have legs before buyers get a real edge. In plain terms: momentum is weak but not extreme — SUI could still fall further.

MACD — Bearish Cross Holding

The daily MACD confirms what the RSI is hinting at. The MACD line is under its signal line, both sitting below the zero line, and the histogram bars are red and growing — that's negative momentum building, not fading. There's no crossover forming yet that would flag a shift back toward buyers.

This lines up cleanly with the channel breakdown on the four-hour chart — momentum and structure are telling the same story today. In plain terms: the trend indicator confirms sellers are still in control right now.

Liquidation Heatmap & Positioning — Who's Actually Selling?

The key map today: a heavy bid wall of roughly 494,000 SUI sits at $0.60, the biggest support shelf on the book. Overhead, a much thinner ask wall of under 100,000 SUI sits at $0.70. In between, the last two weeks of liquidations have piled up right around $0.67–$0.68 above, and a dense $4.6 million cluster just below spot near $0.65 — that's a level that's already been fought over, not a target.

Funding, Positioning & Order Flow

A persistent positive premium is normally the fingerprint of US spot/ETF buying; a discount, like we're seeing now, means American holders are the sellers today. With retail and top traders both net long and aligned, positioning gives no obvious edge to fade right now.

Today's Drivers & The Desk's Trade Plan

Put it all together and today's tape is a genuine tug-of-war. Structure and momentum (RSI, MACD, the 4-hour channel break) all point down. But funding flipping negative, a crowded short base, and a magnet of short liquidations sitting just overhead argue for a sharp squeeze before any real breakdown continues. That's the layered setup this Pulse opened with.

The desk's read: risk/reward on the short side into the $4.6M liquidation cluster near $0.65 is roughly 1:3.1 — favorable, but not without teeth. The one level that kills the trade is a sustained reclaim of the $0.68 mid-sixties zone; above that, the crowded-short setup starts feeding a squeeze toward $0.70 instead of a continuation lower.

Summary

SUI got flushed nearly 5% overnight, structure remains broken on the 4-hour and daily, and RSI/MACD both confirm sellers are still in control — yet funding, open interest, and a discount on Coinbase versus Binance hint that the next sharp move could be a squeeze through the crowded short base above $0.68.

With SUI's market cap near $2.65B and price still miles above its $0.3648 all-time low, the mid-sixties remain the pivot that decides whether this is a healthy pullback or the start of a deeper leg down.

SUI Daily Pulse Aug 17: Bounce Fades Under $0.68

Where We Left It: The Prior Call Is Still Live

Yesterday's Daily Pulse flagged a short from $0.682, targeting $0.664. Since then, SUI hasn't moved much at all — it slipped roughly half a percent, drifting from around $0.678 down to about $0.675. That's not a victory lap, but it's not damage either.

As of writing, SUI is quoted at $0.6779 on CoinMarketCap, up a marginal 0.24% on the day, while CoinGecko shows a nearly identical $0.6767. Coinbase data via Yahoo Finance had SUI slightly higher at $0.6814 in its most recent daily close — small cross-venue gaps like this are normal and, as we'll see later, actually tell a story of their own.

Today's Bias: Fade the Bounce, Don't Chase the Breakout

SUI is trading around $0.675 right now, down slightly on the day after tagging a high near $0.68 overnight. The bigger picture still favors sellers. Price is capped under a descending trendline on the 4-hour chart, and the daily chart remains stuck inside a downward channel that's been intact since July.

Momentum indicators are trying to turn — more on that below — but market structure hasn't confirmed a reversal. That combination is what makes this a fade-the-bounce environment rather than a breakout setup, at least for now.

• Spot: ~$0.675, down modestly on the day
• Overnight high: ~$0.68 (rejected twice)
• 4H structure: capped by falling ceiling
• Daily structure: inside downtrend channel since July peak near $0.80

Chart Breakdown: 15-Minute Squeeze Meets a Falling Ceiling

15-Minute Intraday — Ascending Channel, Losing the Top

Zoom into the 15-minute chart and you can see today's whole story play out. SUI pushed up inside a rising channel, tapped resistance near $0.68 twice, and got turned away both times. It's now drifting back down toward the $0.675 line, which has acted as a magnet for price all session.

The channel is technically still rising, but the swings inside it are getting tighter. That kind of compression usually snaps hard in one direction — and the double rejection at the top is the first tell to watch.

4-Hour Structure — Capped by a Falling Ceiling

The 4-hour chart shows a wedge that's been building since August 9. Every rally since then has run into the same falling trendline, and every dip has found buyers along a rising support line underneath — classic compression where the market can't decide, so it keeps squeezing tighter.

Right now price sits in the middle of that wedge, closer to the lower half. That tells you sellers still hold the last word until the descending line is actually reclaimed.

Short-Term Daily — Still Inside the Downtrend Channel

Stepping back to the daily, SUI has been grinding lower inside a clean channel since the July peak near $0.80. The support zone around $0.65 has been tested and held multiple times, making it the line in the sand for bulls.

Today's price near $0.675 sits comfortably above that floor but still trapped under the channel's falling ceiling. Nothing's broken yet — this is consolidation inside a downtrend, and that distinction matters for how you size any trade.

Momentum Check: RSI Cooling, MACD Flickers Bullish

RSI (14) — Cooling, Not Crashing

The daily RSI sits at 42 — dead-center neutral, neither overbought nor oversold. It's cooled off from the mid-50s back in July, which lines up with price grinding lower, but it hasn't crashed into the 30-zone the way it did in June when SUI truly capitulated.

In plain terms: momentum is calm, not panicked. That leaves the next few candles to decide direction rather than any single indicator.

MACD — A Quiet Bullish Cross, Still Below Zero

Here's the one real divergence today. The daily MACD just flipped bullish — the MACD line crossed above its signal line, and the histogram turned green. Normally that's a green light for bulls.

Liquidation Heatmap and the Levels That Actually Matter

The map above spot shows an ask wall at $0.72 and a dense liquidation pocket near $0.693 — that's the ceiling. Below, the order book's biggest bid wall sits at $0.65, backed by daily support at $0.651, with a liquidation cluster at $0.671 sitting in between.

Spot right now, around $0.675, is sandwiched almost exactly between those two liquidation pools — which is exactly why it's chopping instead of trending.

Positioning, Order Flow, and the Desk Snapshot

Funding is near neutral at roughly +4% annualized — no real skew paying either side. Open interest sits around 116.7 million SUI tokens, basically flat over the week.

Here's the catch: retail accounts are net long at 2.11, and so-called top traders are even longer at 2.53. They're aligned, not fighting each other — which means there's no obvious crowded-short or crowded-long squeeze to fade right now.

Taker flow is balanced near even, and the order book leans 54% bids, with that heavy $0.65 wall doing the real support work. Because retail and top traders are pointed the same direction, positioning alone doesn't hand either side a clean edge today.

The Trade Setup — A 1:2.5 Plan

Putting the structure, momentum, and liquidation map together: SUI is boxed between a $0.693 liquidation pocket above and a $0.671 cluster just below spot, inside a daily downtrend that hasn't been broken since July. The bullish MACD cross is real but unconfirmed — and history (April, July) says these flicker-crosses inside a downtrend tend to fade rather than run.

Summary: What Would Actually Flip This Bearish Bias

SUI's momentum just turned green on the daily MACD, but price is still red on the day, still under the $0.68 ceiling, and still inside a channel that's been falling since July. Retail and top traders are both leaning long, funding is neutral, and the Coinbase-Binance spread shows US-side selling — none of that screams reversal yet.

• Bias flips bullish only on a clean daily close above the falling channel ceiling and a reclaim of $0.693
• Bias stays bearish while price holds under $0.68 with RSI capped near 42-45
• $0.65 remains the line in the sand — a break there opens the door to a deeper leg down
