On September 15, 2025, Optimism/Tether (OPUSDT) opened at $0.7776 at 12:00 ET-1 and closed at $0.7995 at 12:00 ET, reaching a high of $0.8057 and a low of $0.7744. Total 24-hour volume was 12.65 million, with a notional turnover of $10.02 million.

The structure of the 24-hour price action was defined by a strong impulse wave from around $0.7840 to $0.8057, supported by high volume and tight range consolidation. A notable bullish engulfing pattern formed at the start of the upward leg, followed by a series of higher highs and tighter ranges, indicating strong demand. Key support levels include $0.7933 (38.2% Fib) and $0.7891 (61.8% Fib), while resistance is expected around $0.8021 and $0.8057. A long lower shadow at $0.7840 and a morning doji near $0.7985 suggest potential indecision in short-term traders.

Moving averages indicate that the price crossed above both the 20 and 50 EMA on the 15-minute chart during the breakout phase. On the daily chart, the 50 EMA is approaching the 100 EMA from below, suggesting potential for a golden cross. The 200 EMA remains a significant baseline, currently positioned at approximately $0.7795, and could act as a psychological floor if the rally falters.

MACD turned positive early in the 24-hour period and remained above the signal line, confirming bullish momentum. RSI reached overbought levels near 75 during the late morning and afternoon, suggesting exhaustion could follow. However, the price did not retrace aggressively, indicating the market may remain in a short-term rally phase. Bollinger Bands widened as volatility increased, particularly between 04:30 and 05:30 ET, aligning with the breakout. Prices have since been consolidating within the upper third of the bands, suggesting continued risk-on sentiment.

Volume and notional turnover spiked between 05:30 and 06:30 ET, with over 665k units traded at an average price above $0.8030. This aligns with the MACD divergence and confirms the breakout. However, a divergence in volume occurred during the 06:30–06:45 ET window, as the price declined sharply but volume remained moderate, raising concerns about short-term sustainability.

Backtest Hypothesis

The recent OPUSDT price action aligns well with a breakout and pullback-based backtesting strategy, which targets long entries after a confirmed breakout above a key resistance level and a retracement to the 38.2% Fibonacci level. In this case, the breakout above $0.8057 was confirmed by high volume and a strong MACD, followed by a pullback to $0.7995—close to the 38.2% level. A stop-loss could be placed below $0.7933 to manage risk. This approach would have captured the upward leg while minimizing exposure to a potential reversal. The success of this strategy would depend on the stability of volume and the RSI staying above 50 to confirm ongoing bullish momentum.
