Structure & Formations

The candlestick structure shows several bearish patterns, including a bearish engulfing pattern around $4.51 and a long-legged doji near $4.456, indicating indecision and possible exhaustion of sellers. The most notable support level is forming around $4.45, where the price has tested twice within the 24-hour period. Resistance appears to be strengthening around $4.485–$4.495, with failed breakouts evident in the later ET hours.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages are both in a steep downward bias, with the 20-period slightly above the 50-period, suggesting a short-term bearish trend. The daily chart shows the 50, 100, and 200-period EMAs converging between $4.47 and $4.50, with the price currently below all three, indicating potential further downside.

MACD & RSI

The MACD histogram has turned bearish, with the line falling below the signal line during the price drop to $4.45. The RSI has pushed into oversold territory at 28 but has shown signs of divergence—prices continued to drop while RSI failed to make new lows. This may suggest a weakening bearish momentum or a potential short-term bounce, though the broader trend remains bearish.

Bollinger Bands

Bollinger Bands have widened in response to the increased volatility, with the price touching the lower band multiple times as it approached $4.45. This indicates a period of heightened risk and the potential for a rebound or consolidation near support. Price appears to be consolidating in a tight range between $4.45 and $4.47, suggesting a possible breakout or breakdown setup in the near term.

Volume & Turnover

Volume spiked significantly in the 15-minute candle on 2025-09-20 02:15 ET, where the price dropped sharply from $4.478 to $4.435 on high turnover. This suggests heavy liquidation pressure from large holders or algorithms. However, subsequent volume has been declining, indicating potential exhaustion of sellers or reduced conviction in the current downtrend. The price/turnover relationship shows divergence—higher volume is not supporting lower prices—possibly signaling a near-term bottom or a consolidation phase.

Fibonacci Retracements

Applying Fibonacci retracements to the recent 15-minute swing (from $4.512 to $4.420), key levels are forming at 38.2% ($4.477) and 61.8% ($4.457). The price currently appears to be consolidating near the 61.8% level, which has historically acted as a pivot point. A break below $4.45 could target the next level at $4.444, where the 78.6% retracement aligns with the 90% Fibonacci extension from earlier support.

Backtest Hypothesis

The backtesting strategy described involves entering short positions on ATOMUSDT when a bearish engulfing pattern forms and the RSI crosses below 30, while placing a stop above the high of the engulfing pattern. The initial target is set at the 61.8% Fibonacci retracement of the preceding bullish swing, with a trailing stop initiated upon a 10% pullback. Given the recent candlestick patterns and RSI divergence, this strategy would have triggered a short signal near $4.494 and targeted a stop-loss at $4.526, with the first profit target aligned with the current price near $4.457. The current setup appears to confirm the assumptions of the backtest, though the divergence in RSI suggests caution before entering new short positions.
