Structure & Formations

The 24-hour chart shows a bearish bias, with price breaking below the 423,500 psychological level and testing the 419,000–420,000 zone. A bearish engulfing candle formed at 423,653 on 19:45 ET, followed by a large bearish gap and a deep sell-off to 419,401. A 15-minute doji appeared at 421,728 on 07:00 ET, suggesting short-term exhaustion, though this was followed by renewed selling. Key support levels are forming around 419,000 and 418,000, with 415,000 as a potential deeper target. Resistance remains at 423,500 and 425,500.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages both trended lower during the session, with price remaining below both in the final hours. The 50-period MA at ~422,000 failed to hold, reinforcing the bearish momentum. On the daily timeframe, the 50/100/200-period MAs are all in a descending order, with BTCPLN closing below all three, confirming a broader bearish trend.

MACD & RSI

The MACD line showed a bearish crossover, with the histogram narrowing as the sell-off accelerated during the 19:45–20:45 ET period. RSI dropped below 30 early in the morning, hitting a low of 28, signaling oversold conditions. However, buying interest remained weak, as volume failed to rise proportionately. The divergence between RSI and price suggests caution about a potential bounce, though a reversal is not yet confirmed.

Bollinger Bands

Volatility expanded during the session, with the Bollinger Band width reaching a 15-minute high of 4,359 (425,495–421,136) during the 10:15–10:45 ET window. Price spent the majority of the session below the lower band, indicating bearish pressure and a consolidation toward the lower end of the channel. The 20-period standard deviation was elevated, consistent with increased uncertainty and risk of further downside.

Volume & Turnover

Volume spiked during the 19:45–20:45 ET period as price broke through the 423,500 level, with a notable 0.17662 BTC traded in the 19:45 candle. Notional turnover also surged during the same period, confirming the bearish breakout. However, volume during the morning session was relatively weak despite a rebound in price, suggesting a lack of conviction in buying. The divergence between price and volume raises questions about the sustainability of any near-term bounce.

Fibonacci Retracements

Applying Fibonacci retracement levels to the recent swing high of 425,495 and low of 418,011, the 61.8% retracement level is at ~421,300, which was tested and failed to hold. Price now appears to be targeting the 38.2% level (~423,300) as a potential short-term resistance. On the daily chart, the 61.8% retracement level from a broader 2025 high remains above 450,000, indicating a longer-term bearish outlook unless bullish volume emerges.

Backtest Hypothesis

The backtesting strategy outlined in the provided text is based on a combination of RSI divergence, moving average crossovers, and volume confirmation. Given the current setup, a potential short-term reversal could occur if RSI rises above 30 with a surge in volume and price stabilizes above 419,401. However, the broader trend remains bearish, and a test of 418,000 is likely. The strategy would need to factor in the recent bearish engulfing pattern and the failure of the 423,500 level as key entry and exit signals. A stop-loss just above 425,500 may also be prudent to manage risk in a volatile market.
