A 21:45 ET candle saw a 5.3408 to 5.3464 move, followed by consolidation and a strong rally to 5.3527. Key support appears at 5.346–5.349, while resistance is at 5.3523–5.3527. A bullish engulfing pattern is visible in the 23:30 ET candle, signaling a potential continuation of the upward trend.

Moving averages on the 15-minute chart (20/50) suggest a strong short-term upward bias, with price above both. The 20SMA is rising and approaching the 50SMA, hinting at a potential golden cross if this trend continues. On the daily chart, 50/100/200-day moving averages are not provided, but the 15-minute indicators suggest a continuation of the bullish momentum.

MACD shows a strong positive divergence, with the histogram expanding and the line crossing above zero. RSI approaches overbought territory near 70, suggesting exhaustion of the bullish momentum. However, price remains above key moving averages and appears to be consolidating rather than overextended.

The total 24-hour volume is ~32.07 million tether units, and the notional value is ~5.55 billion BRL. There is no clear divergence between volume and price, suggesting strong confirmation of the rally. The final hours show a strong volume spike, particularly in the 14:00–15:30 ET time frame.

Fibonacci retracement levels applied to the recent 15-minute swing from 5.3260 to 5.3527 highlight key levels at 5.3405 (38.2%), 5.3357 (50%), and 5.3309 (61.8%). Price consolidation in the 5.3510–5.3525 range suggests a potential retest of these levels or a breakout above 5.3527.

The next 24 hours may see a test of the 5.3527 level, with a potential continuation of the rally or a pullback to test support at 5.346–5.349. Investors should remain cautious as overbought RSI levels and a consolidating price suggest short-term exhaustion. A break above 5.3527 could signal a broader bullish trend, while a failure to hold above 5.349 may trigger a deeper pullback.

Backtest Hypothesis

The described backtesting strategy suggests a momentum-based approach, emphasizing the use of MACD and RSI as entry signals. Given the current MACD divergence and the RSI near overbought levels, a potential reversal strategy—such as a short bias on a break below 5.3510—may be considered. A long bias could also be justified if price breaks above 5.3527 and confirms with a strong volume spike. However, the consolidation in recent candles and the lack of a strong breakout signal caution in overleveraging. This approach would need to be tested over multiple cycles to ensure it captures the market’s behavior accurately and consistently.
