Structure & Formations

The 15-minute OHLCV data reveals a bearish trend with key support levels forming around 407,800–408,000 PLN and resistance near 418,500–419,000 PLN. Notable bearish engulfing patterns emerged in the early morning hours, especially between 04:00 and 05:15 ET. Doji and long lower shadows appeared in the 08:00–09:00 ET timeframe, hinting at indecision among traders. The most recent candle at 16:00 ET closed near the lower end of its range, reinforcing bearish sentiment.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages are both bearishly aligned, with the price trading below both and converging toward the lower end of the range. On a daily timeframe, the 50-period MA is above the 100- and 200-period MAs, but the recent daily close failed to cross back above the 50-period MA, suggesting ongoing bearish momentum.

MACD & RSI

The MACD line crossed below the signal line in the early hours of the morning, forming a bearish crossover. The histogram has been negative for most of the 24-hour period, indicating weakening bullish momentum. RSI fell into the oversold zone (~30) in the early morning hours and has remained there, but without a corresponding rally in price, this suggests a possible continuation of the bearish trend or a deepening of oversold conditions.

Bollinger Bands

Bollinger Bands have widened significantly as price volatility increased. The closing price of the latest candle (407,897 PLN) sits near the lower band, suggesting a possible bounce or a continuation of the bearish move. The bands also show a moderate contraction during the overnight hours, indicating a period of consolidation before renewed bearish pressure emerged.

Volume & Turnover

Volume spiked in the early morning hours (04:00–06:00 ET) during the sharp price drop to 406,161 PLN, with a total of ~0.31 BTC traded during that time. However, notional turnover (value of BTC traded) remained relatively flat, suggesting that large BTC amounts were traded at lower price levels. This divergence indicates a bearish continuation scenario rather than a short-term bounce.

Fibonacci Retracements

Applying Fibonacci retracement to the 24-hour high of 419,351 PLN and low of 406,161 PLN, the 61.8% level is at ~409,765 PLN and the 38.2% level is at ~413,899 PLN. The price has tested both of these levels and failed to hold, indicating continued bearish pressure. On the 15-minute chart, retracements from the overnight high (~419,351 PLN) to the 06:00 ET low (~406,161 PLN) show the 61.8% level at ~411,600 PLN, which the price has also failed to hold.

Backtest Hypothesis

A potential backtesting strategy for BTCPLN could focus on short-term mean reversion signals within Bollinger Bands. Triggers could include a price crossing the lower band with a MACD bearish crossover and RSI in oversold territory. Stop-loss levels could be placed just above the 61.8% Fibonacci retracement level at ~409,765 PLN. Given the observed behavior of BTCPLN over the past 24 hours, this strategy could be backtested using a 15-minute timeframe with a 20-period Bollinger Band and 20-period EMA. The recent price behavior suggests the strategy may yield profits in a continuation of bearish momentum but may fail during periods of consolidation.
