Structure & Formations

API3USDT displayed a volatile 24-hour range, forming key support levels at 0.9143 and 0.9200 and resistance at 0.9260 and 0.9365. Notable patterns included a bearish engulfing pattern at the 22:30–23:00 ET window and a bullish harami near the 0.9200 level in the early hours of September 17. A doji at 0.9244 on September 16 signaled indecision, followed by a strong bearish continuation in the next time window.

Moving Averages

On the 15-minute chart, price hovered below the 20-period and 50-period moving averages for much of the 24-hour window, indicating bearish bias in the short term. On a daily basis, price held above the 50-period MA but below the 200-period MA, suggesting mixed signals between medium-term strength and long-term bearish pressure.

Backtest Hypothesis

Given the recent volatility and defined support/resistance levels, a mean-reversion strategy using a 20-period and 50-period EMA crossover could be applied. When price closes below the 20-period EMA and retests the 50-period EMA, a long entry may be considered if the RSI shows oversold conditions. Stops would be placed below key support levels, and targets would align with Fibonacci retracements from the 0.9143–0.9365 swing.

MACD & RSI

The MACD line crossed below the signal line in the early evening hours of September 16, confirming a bearish momentum shift that continued through the night. RSI moved into oversold territory below 30 at 0.9175 but failed to hold above that level, suggesting a lack of buying interest. A potential rebound occurred after 05:00 ET as RSI crossed back above 40, indicating a possible short-term recovery.

Bollinger Bands

Price traded within a tight Bollinger Band range from 0.9200 to 0.9260 for several hours before breaking out to the upside in the early hours of September 17. The upper band was tested and rejected at 0.9365, which may act as a near-term ceiling. A contraction in band width earlier in the session suggested increased volatility ahead, which materialized as price broke out of the range.

Volume & Turnover

Volume spiked dramatically at 02:30–02:45 ET and again at 05:00–05:15 ET, both times coinciding with significant price moves. Notional turnover also surged during these intervals, confirming the strength of the price movements. Divergence was observed in the morning hours when volume increased but price declined, suggesting potential bearish exhaustion or consolidation.

Fibonacci Retracements

Applying Fibonacci retracements to the 0.9143–0.9365 swing, key levels at 0.9256 (38.2%) and 0.9296 (61.8%) were tested multiple times. The 61.8% level held firm as resistance in the early morning of September 17, after which price reversed lower. These levels may continue to influence short-term behavior and could be used as reference points for potential entries or exits.

Forward-Looking View and Risk Caveat

Looking ahead, traders should monitor the 0.9200–0.9260 range for potential consolidation or breakout, as well as RSI for signs of overbought or oversold conditions. While the 0.9200 level provides near-term support, a breakdown could lead to a retest of 0.9143. Volatility remains elevated, and sudden moves are possible, especially as volume shows signs of increasing in key time windows.
