Structure & Formations

The price of Bitcoin/Zloty formed a distinct intraday swing pattern as it broke below a consolidation range in the 15-minute chart after reaching a low at 418,225.0. A strong rebound followed into the later part of the session, forming a bullish reversal candlestick formation around the 19:30–20:30 ET timeframe. A notable 15-minute bearish engulfing pattern emerged near the session low, suggesting initial downward pressure. Later, an engulfing bullish pattern indicated a short-term reversal. A key support level was identified at 418,225.0, and a resistance level appeared at 422,525.0. A doji candle at 03:30 ET suggested indecision during a sharp sell-off. The price structure points to a potential test of the 422,525.0 resistance in the near term, with 418,225.0 serving as the first line of defense.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages showed a tightening crossover at around 419,600.0–420,000.0, confirming a potential short-term reversal in the trend. On the daily chart, the 50-period moving average (approx. 419,500.0) appears to be a critical support level, while the 200-period moving average (approx. 418,400.0) acts as a baseline for long-term trend direction. The price closing above the 50-period line signals a potential continuation of the upward bias into the next 24 hours.

MACD & RSI

The MACD line crossed above the signal line in the latter half of the session, confirming a bullish momentum shift following the initial sell-off. The RSI reached overbought territory near the 80 level during the intraday high at 422,525.0, which typically indicates a possible pullback. However, the price remained above the 50 RSI level for most of the session, suggesting a continuation of buyer dominance. The divergence between the RSI and price was minimal, reinforcing the integrity of the recent upward move.

Bollinger Bands

Bollinger Bands showed significant expansion during the sharp intraday rally and sell-off, indicating increased volatility in the market. The price briefly touched the upper band at 422,525.0, signaling strong momentum, and tested the lower band during the consolidation phase. The mid-band hovered around 419,500.0, which coincides with key moving averages. The expansion in band width suggests a potential for further price discovery, particularly toward the upper side if the current bullish trend continues.

Volume & Turnover

Volume remained relatively subdued during the initial sell-off but increased sharply during the late session rebound. The volume spike at 19:30–20:30 ET coincided with a sharp price reversal, confirming the move’s legitimacy. Notional turnover followed a similar pattern, with a significant increase during the late rebound. The divergence between volume and price wasn’t evident, indicating that the move was supported by genuine buying interest rather than thin liquidity.

Fibonacci Retracements

Applying Fibonacci retracements to the 15-minute swing from the low of 418,225.0 to the high of 422,525.0, key levels were identified: the 38.2% retracement at ~420,200.0 and the 61.8% retracement at ~419,800.0. The price closed near the 38.2% level, suggesting a possible continuation of the upward movement if the 422,525.0 resistance is tested and held.

Backtest Hypothesis

A potential backtesting strategy could be built on the convergence of the 15-minute MACD crossover with a bullish engulfing pattern and a retest of the 38.2% Fibonacci retracement level. This combination of price action and momentum indicators could form the basis for a buy signal with a stop-loss below the recent support at 418,225.0 and a take-profit near the 422,525.0 resistance. Over a 48-hour time horizon, this strategy might capture short-term bullish momentum while managing risk with clear price barriers.
