The Yearn.finance/Tether (YFIUSDT) pair opened at $5362 on 2025-09-17 at 12:00 ET, reached an intraday high of $5568, and closed at $5555 by 12:00 ET on 2025-09-18. The 24-hour period saw strong accumulation above key resistance levels, with total volume of 124.9714 YFI and a notional turnover of $677,558.57. Price broke above a prior consolidation range and tested a 15-minute Fibonacci 61.8% retracement at $5564 before stabilizing.

Structure & Formations

Price advanced through several key levels on the 15-minute chart, with a notable bullish engulfing pattern forming around $5460 and a higher inside bar forming near $5564—both signaling strong accumulation. A descending triangle formation from $5340 to $5460 was decisively broken to the upside, with a prior high at $5568 offering immediate overhead resistance. The 50-period moving average on the 15-minute chart acted as dynamic support, while the 20-period line reinforced the bullish bias.

Moving Averages & Momentum Indicators

On the 15-minute chart, the 20-period and 50-period moving averages trended higher, with the 20-period line above the 50-period, confirming a bullish crossover. The MACD histogram showed positive divergence after a bearish crossover at $5450, while the RSI hovered near 75, indicating overbought conditions. On the daily chart, the 50-period and 100-period moving averages were aligned with the price action, suggesting that the short-term bullish trend is likely to continue unless a significant bearish reversal emerges.

Bollinger Bands & Volatility

Bollinger Bands expanded as price surged past the upper band on multiple occasions, particularly after the $5550 level. A period of tight consolidation between $5420 and $5460 was followed by a sharp breakout, indicating increased volatility. Price remains within a 1.5% range above the upper band, with a potential test of the 2.5% upper deviation expected if buyers remain aggressive.

Volume & Turnover Analysis

Volume spiked during the final push above $5560, particularly in the 03:00–04:00 ET window when price advanced from $5564 to $5582. Notional turnover confirmed the strength of the move, aligning with price and reinforcing the likelihood of a continuation pattern. However, a divergence between rising price and declining volume at the peak may indicate exhaustion. Investors should watch for a confirmation candle above $5582 or a rejection below $5550 to assess the sustainability of the trend.

Fibonacci Retracements

Recent 15-minute swings showed YFIUSDT testing the 61.8% Fibonacci retracement at $5564 and a 78.6% level at $5575, both of which acted as strong support during pullbacks. On the daily chart, a key Fibonacci 50% retracement is at $5498, and a 61.8% retracement at $5433 may serve as a critical support zone if the price corrects. A break below $5400 would invalidate the current bullish thesis and open the door to a deeper correction toward $5340.

Backtest Hypothesis

A backtesting strategy that targets long entries on a bullish engulfing pattern above a 20-period moving average and a RSI crossover above 50 may align well with the current setup. Given the strong volume confirmation and the recent price action near key Fibonacci levels, a buy signal triggered by a breakout above the $5564 level could be paired with a stop-loss just below $5540. A target of $5585–$5600 could be considered for a 1–2% move, with an exit on a close below $5530 if signs of bearish momentum emerge.
