The Cosmos/Tether pair (ATOMUSDT) opened at $3.997 on 2025-09-30 12:00 ET and surged to a high of $4.257 by 09:15 ET on October 1. A low of $3.995 was recorded just before the session began, and price closed at $4.194 at 12:00 ET on the 1st. Total volume for the 24-hour period was 1,150,125.16 ATOM, with notional turnover reaching $4.62 million.

The price action displayed a strong bullish bias during the first half of the session, with a decisive break above prior resistance at $4.200 triggering a wave of accumulation. The move higher saw a strong confirmation from volume and turnover, particularly between 08:45 and 09:30 ET, where large orders pushed the price past 4.230. A doji at 09:30 ET suggested hesitation before the pullback began. The 15-minute chart formed a small bearish engulfing pattern near 4.232, followed by a bearish divergence in RSI and MACD, hinting at short-term profit-taking.

Bollinger Bands were at their widest in the morning session, with price reaching the upper band before reversing lower. This expansion suggests increased market participation and heightened risk. The RSI climbed to 73 at the peak, indicating overbought conditions, while MACD showed a bearish crossover during the pullback phase. The 20-period EMA crossed above the 50-period line in the morning, confirming bullish momentum initially, but the 50-period line began to act as dynamic resistance as the price declined in the afternoon.

Fibonacci levels on the 15-minute chart revealed a 61.8% retracement at 4.204, which became a key pivot. On the daily chart, the 50-day MA (4.150) and 200-day MA (4.120) are close to converging, which could lead to a potential crossover if the current downward trend continues. Volume and turnover diverged in the afternoon, with price falling while turnover remained elevated, indicating possible distribution. The next 24 hours may bring a test of the 4.195–4.200 range, with the 20-period EMA likely to offer support. Investors should watch for a breakdown below 4.180 to confirm a bearish bias.

The 15-minute MACD histogram shows a bearish crossover coinciding with the pullback. RSI peaked near overbought levels before a reversal, signaling a potential exhaustion in the bullish momentum.

Backtest Hypothesis
A backtesting strategy could look to capture the pullback from the overbought RSI peak by entering short positions on a close below the 20-period EMA with a stop loss just above the recent high of 4.218. This approach would aim to capitalize on the bearish engulfing pattern and MACD divergence while limiting downside risk. A trailing stop could be implemented as price consolidates near the 4.195–4.200 zone.
