Bitcoin has received a fresh buy signal from the Supertrend indicator, which turned green again as the cryptocurrency traded around $84,000. Crypto commentator Rand Group noted that the previous green signal appeared near $16,000 and remained in place for about three years, during which Bitcoin rose roughly 700%. Bitcoin later surpassed $100,000 in December 2024 and reached around $120,000 by October 2025 before the signal eventually turned into a sell indication. After falling from above $100,000 to about $57,700 in July 2026, Bitcoin has surged 51% from that cycle low over the past two months. The Supertrend, which combines price and volatility to indicate market direction, generally uses green for an upward trend and red for a downward trend. The latest signal points to a possible recovery but does not ensure a repeat of the earlier rally. Bitcoin also moved back above its 365-day moving average near $83,000. CryptoQuant founder Ki Young Ju identified that move as the signal traders were watching for the bear market to end and institutional FOMO (fear of missing out) to return. Analyst Ted Pillows cited a higher weekly high and a move above the 50-week moving average as evidence that Bitcoin's bottom may already be in. The next major technical level is around $88,761, representing Bitcoin's two-year moving average. Bitcoin's September 20 weekly close at $81,159 was about 3% above its 50-week moving average and 24% above its 200-week moving average, marking the first close above the 50-week average in 45 weeks. Historically, recoveries above that average have often been followed by further gains.
