Market Overview and Daily Performance

Tether/Mexican Peso (USDTMXN) opened at 18.87 on 2025-10-12 at 12:00 ET and closed at 18.54 by 12:00 ET on 2025-10-13. The pair reached a high of 18.98 and a low of 18.51 during the 24-hour window, with a total traded volume of 1,129,422 and a notional turnover of 20.99 million MXN. The price trend shifted decisively lower after a consolidation period, with bearish momentum confirming a potential short-term reversal.

Structure & Formations

Key support levels emerged at 18.50–18.55, as evidenced by a strong rejection of price during the 05:00–07:00 ET window. A large bearish engulfing pattern formed during the 03:30–03:45 ET candle, confirming a shift in sentiment. A doji at 04:45 ET also signaled indecision before the downward move accelerated.

Moving Averages and MACD

The 20-period and 50-period SMAs on the 15-minute chart crossed bearishly as the price dropped below both lines after 03:30 ET. MACD turned negative with a bearish crossover, reinforcing the downward bias. The 50-period daily MA is currently at 18.60, and the price is below this level, indicating a potential continuation of the bearish trend.

Volatility, Bollinger Bands, and Fibonacci

Bollinger Bands expanded significantly during the early morning hours, with the price trading near the lower band by 05:00 ET. The 61.8% Fibonacci retracement level from the recent high at 18.98 and low at 18.51 is near 18.57, which appears to be acting as a short-term floor. Price has yet to show signs of breaking this support convincingly.

Volume and Turnover

Volume spiked to over 82,000 units during the 03:30–03:45 ET candle, aligning with the bearish engulfing pattern. Notional turnover also surged during this window, confirming the bearish signal. A divergence in price and volume was observed during the 10:00–11:00 AM ET session, where volume remained subdued despite minor price rebounds, suggesting a lack of follow-through in buying interest.

Backtest Hypothesis

Given the bearish momentum and oversold RSI levels observed in this 24-hour window, a backtest strategy could focus on shorting USDTMXN when RSI drops below 30 and exits when it closes above 30, using a stop-loss above the 20-period SMA. This approach would align with the observed bearish patterns and high volume confirmation. Testing this strategy on a single security like USDTMXN would provide a clear view of how RSI and volume-driven entries perform in a low-latency, high-volume stablecoin pair.
