Over the 24-hour period, total volume traded amounted to 65,797.0 units, with notional turnover reaching 1,354,583.61 CZK. Price action reflected a bearish correction from 20.66 toward key support levels in the 20.58–20.61 range.

Structure & Key Levels

Price tested the 20.66 resistance in the early hours of the session with a brief bullish breakout, but failed to hold above that level, retreating toward 20.61–20.58, where a cluster of bullish volume and a doji-like structure suggest accumulation. A bearish engulfing pattern was visible between 04:45 and 05:00 ET as price fell from 20.63 to 20.61, reinforcing the bearish sentiment. The 20.53–20.55 range now acts as a critical support level, with a potential bounce or breakdown possible in the next 24 hours.

Technical Indicators and Momentum

On the 15-minute chart, the 20-period and 50-period moving averages remained in a bullish alignment, but price has crossed below both, suggesting short-term bearish momentum. MACD is in a bearish crossover, with a recent negative divergence visible as price bottomed at 20.53 while the MACD line failed to do the same. RSI is in neutral territory, hovering around 50, indicating a potential pause in directional bias. Bollinger Bands show a wide range during the overnight session, with a reversion toward the mid-band occurring after 08:00 ET.

A key Fibonacci retracement level at 20.63 (61.8% of the 20.53–20.66 move) appears to be a key psychological level, with price bouncing off it in multiple instances. Further downward movement could test the 20.56 (38.2%) and 20.53 (61.8%) retracement levels, where a bullish reversal or continuation may be determined.

Backtest Hypothesis

The backtesting strategy in question relies on a breakout confirmation system using Bollinger Bands and RSI. A long signal is triggered when price breaks above the upper Bollinger Band and RSI closes above 55, suggesting momentum. Conversely, a short signal occurs when price drops below the lower Bollinger Band and RSI falls below 45, indicating bearish strength. Given the current setup, with price near the lower Bollinger Band and RSI stabilizing around 50, a bearish trigger may be in the works, provided price does not rally above 20.63–20.64. This strategy would need to be paired with a stop-loss at the next Fibonacci level (e.g., 20.63 for short bias) to manage downside risk.
