Bitcoin/Mexican Peso (BTCMXN) opened at 2154996 MXN at 12:00 ET - 1 and closed at 2141101 MXN by 12:00 ET, trading as high as 2165350 MXN and as low as 2133712 MXN. Total trading volume was 1.298 BTC, with a notional turnover of approximately 281.7 million MXN.

The 24-hour period was marked by a decisive breakdown after a failed attempt to test resistance at 2165k. A bearish engulfing candle at 16:00 ET - 1 initiated the decline, followed by a series of lower closes and expanding volatility as price moved below 2152k and tested 2140k. This breakdown appears to have confirmed a medium-term bearish bias, with the 50-period MA (15-min chart) now acting as a dynamic overhead pressure at ~2165k.

Key support levels emerged at 2152k and 2140k, with the latter being a prior consolidation zone. A doji at 2140000 MXN on 15:00 ET suggested a temporary pause, but bearish momentum regained control in the afternoon session. The 200-period MA on the daily chart is estimated at ~2185k, providing a potential long-term resistance target. A retest of 2140k may trigger further consolidation, with 2130k as the next likely support threshold.

On the momentum front, the 15-minute RSI dropped below 30 into oversold territory, indicating potential for a short-term bounce. However, the MACD histogram remained bearish with a negative divergence to price, suggesting caution on long bias. Volatility as measured by Bollinger Band width increased significantly before the breakdown, aligning with the sharp sell-off. Price closed near the lower band at 12:00 ET, reinforcing the bearish narrative.

Backtest Hypothesis
Given the breakdown pattern and RSI divergence, a backtest strategy could focus on shorting BTCMXN at key support levels with stops above 2152k and targets at 2130k and 2120k. A potential long bias may be considered if price retests 2140k with a bullish reversal candle, but this should be cautiously approached due to the recent bearish momentum. Using 50-period and 20-period MAs as dynamic levels can help refine entry and exit points.
