The YFIUSDT pair opened at 5357 on 2025-09-19 at 12:00 ET and reached a high of 5389 before closing at 5385 on 2025-09-20 at the same hour. The 24-hour total volume was approximately 106.87 BTC, with a notional turnover of $578,347. Price action featured a sharp decline to 5265 followed by a partial recovery, with key resistance appearing around 5370–5380 and strong support at 5290–5300. A notable bearish engulfing pattern was observed in the 19:00–20:00 ET timeframe, followed by a bullish reversal late in the session.

The 20-period moving average on the 15-minute chart currently sits near 5330, below the 50-period at 5350, suggesting a bearish bias in the short term. The daily 50-period MA is at 5365, while the 200-period MA sits near 5270, indicating a more neutral-to-bullish outlook over a longer horizon. MACD crossed below the signal line in early hours, confirming bearish momentum that faded somewhat toward the close. The RSI moved into overbought territory as price closed near intraday highs, suggesting a potential short-term correction.

Volatility increased significantly during the price decline, with Bollinger Bands expanding from a narrow range. Price spent several hours outside the upper band during the recovery phase, suggesting strength in the move. However, the divergence between the high-volume decline and the low-volume recovery suggests caution. The 38.2% Fibonacci retracement level at 5346 was broken early, but the 61.8% level at 5371 acted as a pivot during the recovery. This suggests that key support and resistance levels are being tested and may remain relevant.

Backtest Hypothesis
The data aligns with a backtest strategy focusing on Fibonacci levels and RSI signals. A short bias could have been triggered when RSI crossed below 50 and the price broke the 38.2% retracement level during the early decline. A long entry could have followed when RSI crossed back above 50 and the price crossed the 61.8% retracement level. This strategy would need to incorporate a stop-loss below key support at 5290 and a take-profit near 5380. Given the high volatility and mixed volume signals, this approach should include a trailing stop to manage risk effectively.
