Bitcoin volatility back for monthly close
Data from Cointelegraph Markets Pro and TradingView showed BTC/USD gaining 3% in a single hourly candle to hit local highs of $20,171 on Bitstamp.
The move followed predictions from traders, who were looking for slightly higher levels to precede a fresh downside move.
“Moving my stop to my entry now at 19.3k but letting it ride first to 21.7k where I think there’s some major resistance,” popular trader Pentoshi wrote in part of a fresh Twitter update about his trading plans.
“Looks like strength to me,” trading account IncomeSharks continued.
“Great way to finish the week off after seeing people switch back to being bearish every other day depending on the candle color.”
Fellow trader Cheds called $20,000 a “pivot,” focusing attention on the psychologically significant level, having previously flagged declining U.S. dollar strength — a classic catalyst for risk asset performance. 
The downturn in the U.S. dollar index (DXY) continued on the day, approaching 112 points after meeting resistance during a rebound.

A further macro catalyst came in the form of United States Personal Consumption Expenditures Price Index (PCE) data, which came in hotter than expected, increasing pressure on the Federal Reserve.
In Europe, record Consumer Price Index (CPI) readings caused shock for some, highlights including The Netherlands’ 17.1% year-on-year increase.
The fate of September’s candle hangs in the balance
