Structure & Formations

The 15-minute OHLC data shows a strong bullish reversal pattern forming at the 0.6970–0.7002 range, with an engulfing candle at 18:45 ET (0.7050–0.6934). Later, a high-volume bearish candle at 19:45 ET (0.7063–0.7066) suggested short-term profit-taking. A significant bullish trend emerged after 20:15 ET, forming a clear ascending triangle pattern, with resistance at 0.7111–0.7166 and support at 0.7111–0.7104. This area appears to be a key battleground for buyers and sellers in the next 24 hours.

Moving Averages

On the 15-minute chart, the 20-period and 50-period EMA crossed above the price in the late night hours (03:15–05:00 ET), reinforcing the bullish bias. On the daily chart, the price remains above the 50, 100, and 200 EMA lines, suggesting the longer-term trend remains intact. However, the 50 EMA is beginning to flatten, signaling a potential slowdown in bullish momentum. The 15-minute MA crossover could serve as a near-term signal for short-term traders.

MACD & RSI

The 15-minute MACD showed a bullish crossover just after 03:15 ET, with a histogram that gradually expanded until 05:30 ET before tapering off. RSI reached overbought territory (70+) at 04:30 ET, confirming the aggressive rally. A bearish divergence appears as RSI peaked at 72 while price continued to climb. This divergence suggests the upward momentum may be waning.

Bollinger Bands

Volatility expanded sharply around 18:15 ET as the price broke out of a tight Bollinger band contraction. Price remained above the midline for much of the night, with a brief retest at 0.7175–0.7185. The 15-minute Bollinger bands widened to ~0.0050–0.0065 range by 02:00 ET, indicating increased uncertainty. If the price continues to stay within the bands, it may consolidate into a higher range for the next 24 hours.

Volume & Turnover

Trading volume spiked to 85,923.3 at 20:15 ET and remained above 40,000 until 04:15 ET, with notional turnover rising in tandem. A divergence between price and volume occurred after 05:30 ET, with price continuing higher while volume declined. This suggests a possible exhaustion phase in the rally. However, a strong volume spike at 03:15 ET confirmed the reversal at the 0.7104 level, indicating a valid short-term pivot.

Fibonacci Retracements

Applying Fibonacci to the 15-minute swing from 0.6973 to 0.7047 (09:30–10:45 ET), the 0.7104 level aligns with the 61.8% retracement level. This level held as support at 04:30 ET. For the daily swing from 0.6926 to 0.7099 (19:15 ET 2025-09-17 to 18:30 ET 2025-09-18), the 0.7175 level coincides with the 38.2% retracement, where price found strong support overnight. These levels may continue to act as pivot points in the near term.

Backtest Hypothesis

A potential backtesting strategy for DIA/Tether could involve entering long positions at the 61.8% Fibonacci retracement level when the 20 EMA crosses above the 50 EMA, with a stop-loss placed just below the 38.2% retracement. A profit target could be set at the most recent swing high on the 15-minute chart. This strategy would leverage the convergence of trend and momentum indicators, with the Bollinger bands and RSI overbought/oversold levels providing risk management signals. Given the recent price behavior, this approach may yield favorable risk-to-reward ratios during periods of high volatility, especially when volume confirms key price levels.
