Sunday's quote of $81,631.68 on CoinDesk's front page left bitcoin almost exactly where Friday ended. Bitcoin.com News, in a report published October 17 at 4:30 p.m. Eastern, put it near $81,500 inside a 24-hour band of $81,108.80 to $81,733.01, on $13.967 billion of volume and a market cap of about $1.639 trillion. A quiet weekend followed a rough week, and the chart carries both. Price sits under the short averages, the 10-period exponential at $82,343 and the 20-period simple at $83,405, yet still above the 50-period pair at $80,416 and $81,322: short-term trend down, medium-term trend intact. Momentum adds little clarity, with the relative strength index at 46 and an overall neutral technical rating. Support stacks up at $81,000, then $80,000, then $79,694 on the four-hour chart, and a daily break would open $78,000. Above, sellers have appeared at $81,700 to $82,000 and again at $82,500, with heavier resistance at $83,000 and the $84,254 rejection. When price coils this tightly the eventual move tends to be larger, and the Fed meeting on October 27 and 28 looks like the likeliest trigger.
