The pair reached a high of 4.5e-06 and a low of 4.21e-06, reflecting strong buyer participation.

The price action unfolded in a bullish manner, with a steady climb supported by increasing volume in the late hours of the previous day and early morning of 2025-09-18. A key breakout above the 20- and 50-period SMAs confirmed a shift in sentiment. A bullish engulfing pattern appeared around the 22:45 candle (ET) and was followed by a series of higher closes and rising highs. The price is currently sitting just below the upper Bollinger Band, indicating elevated volatility and potential continuation of the uptrend.

Relative Strength Index (RSI) reached 61.8 at the session high, signaling overbought territory, while MACD showed a positive divergence with price, suggesting that the bullish momentum may persist despite the elevated RSI. A notable bullish divergence was observed in the volume profile: higher closes were accompanied by increasing notional turnover, especially after 21:00 ET, which reinforced the validity of the uptrend.

The 4.47e-06 level has emerged as a critical price point, with support expected to test at 4.42e-06 (a recent pullback low) and resistance likely at 4.5e-06. The 61.8% Fibonacci retracement of the most recent swing up is aligned with this level, making it a potential confluence area of importance.

The Backtest Hypothesis involves a breakout strategy where trades are triggered when price closes above a 20-period SMA with increasing volume and divergent RSI behavior. Given the current setup—price above moving averages, rising volume, and diverging RSI—this strategy could align well with the ARBBTC pair over the next 24 hours. A stop-loss could be placed below 4.42e-06, while targets could be set at 4.5e-06 and 4.53e-06 for a conservative to aggressive approach.
