The Tether/Brazilian Real (USDTBRL) pair opened at 5.6198 on October 11 at 12:00 ET, surged to a high of 5.6500, dropped to a low of 5.5750, and closed at 5.6215 on October 12. The total volume traded over the 24-hour window was 10.1M BRL, with notional turnover reaching approximately 56.3M BRL.

The 15-minute OHLCV data revealed multiple key support and resistance levels. A strong bearish breakdown occurred after 03:30 ET when the price dropped from 5.6240 to 5.6101, forming a bearish engulfing pattern. A notable support was found at 5.5750, where the price consolidated briefly. Resistance levels were identified around 5.6300 and 5.6400, with price failing to hold above either during the session. A bullish engulfing pattern emerged at the session start, suggesting short-term buying pressure, but was ultimately negated by larger bearish volume.

The 20-period and 50-period moving averages on the 15-minute chart indicated a bearish crossover in the late hours of the session, aligning with the price’s sharp drop. On the daily chart, the 50-period moving average currently sits above the 200-period line, but the price is below both, indicating short-term bearish momentum and a possible consolidation phase.

MACD diverged from price action in the early morning hours, with momentum turning negative while the price remained flat. RSI reached oversold territory (below 30) by 05:15 ET, signaling a possible short-term rebound. Bollinger Bands showed expansion during the late night selloff, with price dropping significantly below the 20-period lower band before consolidating in the morning.

The Fibonacci retracement levels from the 5.5750 to 5.6500 swing identified key retracement levels at 5.6125 (38.2%) and 5.5965 (61.8%). Price found support around the 38.2% level and bounced off it briefly, but failed to sustain a recovery.

Volume and turnover data showed a clear divergence after the 03:30 ET selloff. While volume surged to over 1.3M BRL, turnover dropped sharply, indicating that large volumes did not translate to sustained price movement. This divergence suggests a lack of conviction in the move lower and could hint at a possible consolidation or reversal.

Looking ahead, the market may test the 5.6125 level again for support, with a potential bounce back to the 5.6300–5.6400 resistance range if buyers step in. Traders should remain cautious, however, as the recent volatility and divergences in volume and momentum suggest the market is in a transitional phase. A break below 5.5900 could signal further downward risk, while a recovery above 5.6300 could indicate renewed buyer interest.

Backtest Hypothesis

A potential backtesting strategy involves using the 20-period and 50-period moving averages on the 15-minute chart for entries and exits, combined with RSI for filtering overbought/oversold conditions. Long entries could be triggered when the 20-period MA crosses above the 50-period MA and RSI is below 30, while short entries could be initiated when the 20-period MA crosses below the 50-period MA and RSI is above 70. Stop-loss levels could be placed at key Fibonacci retracement levels, such as 5.6125 and 5.5965, with take-profit targets aligned with the 5.6300–5.6400 resistance cluster. This strategy leverages the recent trend divergence and volatility to capitalize on short-term reversals or continuation moves.
