Aptos/Yen (APTJPY) opened at 665.3 Yen on 2025-09-12 at 12:00 ET and closed at 689.2 Yen at 12:00 ET the following day. The pair reached a high of 700.4 Yen and a low of 680.6 Yen, with a total volume of 6,494.79 and notional turnover of 4,563,394.94 Yen over the 24-hour period.

Structure & Formations

Price action on the 15-minute chart revealed several key support and resistance levels. A strong resistance cluster formed between 690.0 and 695.0 Yen, which was tested and broken late in the session. A bullish engulfing pattern was identified at 693.3 Yen, followed by a continuation rally. A notable bearish reversal pattern emerged at 688.5 Yen, where price paused briefly before resuming higher. The 680.0–685.0 Yen range appears to be a critical support zone, with price bouncing from it multiple times.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages both trended upwards, with price above both. This suggests a short-term bullish bias. On the daily chart, price remained above the 50 and 100-period moving averages but approached the 200-period, indicating potential for a reversal or consolidation phase.

MACD & RSI

The 15-minute MACD showed a bullish crossover early in the session, followed by a strong positive divergence with price in the afternoon. RSI reached overbought territory multiple times, most recently at 700.4 Yen, suggesting a possible pullback. However, bullish momentum appears to be maintaining upward pressure, especially during high-volume periods.

Bollinger Bands

Volatility expanded significantly during the session, with Bollinger Bands widening to a range of approximately 20 Yen. Price spent most of the session near or above the upper band, indicating strong buying pressure. A brief contraction occurred around 688.5 Yen, followed by a sharp breakout. Price remains above the 15-minute band in a potential overbought condition.

Volume & Turnover

Volume spiked during the morning hours and again in the late afternoon and evening, coinciding with strong upward moves. Notional turnover confirmed these rallies, suggesting liquidity and order flow support the bullish trend. However, a divergence in the early morning at 688.5 Yen, where price fell but volume remained low, could signal a potential short-term reversal.

Fibonacci Retracements

On the 15-minute chart, price broke above the 61.8% Fibonacci level at 690.0 Yen, extending into the 70.2% zone at 697.6 Yen. On the daily chart, the 38.2% level at 693.0 Yen was briefly tested but not decisively broken. These levels will be key for determining the sustainability of the current rally.

Backtest Hypothesis

Given the strong volume and price action observed, a potential backtest strategy could involve entering a long position when price breaks above the 690.0 Yen resistance, confirmed by a bullish engulfing candle and a positive MACD crossover. A stop-loss could be placed just below the 688.0 Yen pivot, with a target at the 70.2% Fibonacci extension level. This approach aligns with the observed support and resistance levels and leverages the strong volume and momentum signals observed in the past 24 hours.
