The same asset reads perfectly directional on the monthly horizon and almost purely choppy on the near-term one. ## Key takeaways - Solana flipped from conflicting back to aligned_down as the 3D trend turned over; price 73.38 is down 5.86% on the week, the largest decline of the three assets covered. - The monthly efficiency ratio reached 1.00 — the maximum the metric can register — while the 3D efficiency ratio collapsed from 0.21 to 0.08, the lowest reading in this week coverage. - The two-touch 3D support at 76.165 from last week no longer sits below price; the scan now flags 76.09 as nearest 3D resistance, in the same region. - Momentum cooled on all three horizons: 3D RSI 49.3 to 44.2, weekly 41.0 to 38.3, monthly 41.2 to 40.2. Price is 41.97% below the monthly 20-EMA at 126.45. - Near-term structure is thin — every 3D support flagged (67.50, 64.04, 60.13) carries a single touch — and no order block is flagged on the 3D or monthly in either direction. ## What changed since last week Last week Solana read **conflicting**, with the 3D trend having ticked up (weakly, efficiency ratio 0.21, RSI 49.3) against a down weekly and a strongly down monthly. That near-term uptick is gone. The 3D trend has flipped back to down and Solana is **aligned_down across all three timeframes** again. Price is 73.38, down 5.86% from 77.95 — the largest weekly decline of the three assets we cover. The two-touch 3D support at 76.165 flagged in last week snapshot no longer holds price above it; spot now sits 3.66% below that level, and our scan currently flags 76.09 as the nearest 3D resistance, placing the freshly-flagged overhead level in the same region that carried support a week ago. Momentum cooled on every horizon: 3D RSI 49.3 to 44.2 (neutral into bearish), weekly RSI 41.0 to 38.3, monthly RSI 41.2 to 40.2. And the two efficiency ratios moved in opposite directions — the monthly from 0.94 to **1.00**, the 3D from 0.21 to **0.08**. ## The efficiency-ratio split That divergence is the most distinctive thing in the Solana snapshot, so it is worth being precise about it. The efficiency ratio compares net directional travel to the total path taken: readings near 1.00 describe a move that went almost straight from start to finish, readings near zero describe a path that covered a lot of ground and ended near where it began. Solana currently registers both extremes at once. The **monthly** efficiency ratio of 1.00 is the ceiling of the metric — the monthly leg is as directionally clean as this measure can report, and it is a downtrend at strong strength, with price 41.97% below the monthly 20-EMA at 126.45. The **3D** efficiency ratio of 0.08 is the lowest reading anywhere in our three-asset coverage this week: near-term trade has been a grind rather than a slide, and the down label there carries only weak strength. The 3D moving averages say the same thing. Price at 73.38 is just 0.41% below the 20-period simple average at 73.68 — essentially on it — while sitting 3.05% below the 20-EMA at 75.69. On the near-term horizon, price is close to its own recent mean; on the monthly horizon it is far from it. ## The multi-timeframe read The **3D** is down at weak strength, momentum bearish at RSI 44.2, ATR 5.62 — about 7.7% of price, the widest ATR-to-price ratio of the three assets, as it was last week. The **weekly** is down at weak strength with an efficiency ratio of 0.26 and RSI at 38.3, the lowest weekly RSI in our coverage. Price is 7.20% below the weekly 20-EMA at 79.08, and weekly ATR of 9.78 runs about 13.3% of price. The **monthly** is the strong, directional one described above: down, strong, efficiency ratio 1.00, RSI 40.2. ## Levels and zones Near-term structure here is notably thin. Every 3D support the scan flags — 67.50, 64.04 and 60.13 — carries a **single touch**, as does the nearest resistance at 76.09. The most-tested resistance on the 3D is 92.322 with five touches, well above spot; on the weekly, the nearest support at 67.50 (one touch, 8.71% below price) is followed by 60.13. One transparency note on the monthly: the only support that scan returns is 15.9975 with four touches. That is an artifact of there being no intervening monthly pivot low between it and current price, not a level with any near-term relevance — we flag it rather than narrate it, and near-term structure in this asset rests on the 3D and weekly levels instead. On zones, the 3D and monthly scans flag **no order blocks in either direction**, and the only zone in the whole snapshot is a bearish weekly block at 132.67 to 143.48, now 29 bars old and far above price. Solana therefore has the emptiest zone map of the three assets this week — no unmitigated demand zone flagged beneath price on any timeframe, and no near-term supply zone above it either. ## Cross-asset context Running the same read weekly across BTC, ETH and SOL makes the rotation legible. Last week Ethereum and Solana both showed a 3D uptick while Bitcoin alone read aligned_down. Solana has now flipped back and joined Bitcoin in aligned_down, and Ethereum is the only one of the three left with a timeframe pointing up. --- *MoonWire surfaces and summarizes public crypto news.* **General information only — not financial advice.** MoonWire Ltd. is not licensed by ASIC and holds no AFSL.
