Contentos/Tether (COSUSDT) opened at 0.003292 on 2025-09-18 at 12:00 ET and closed at 0.00321 at 12:00 ET on 2025-09-19. The 24-hour range extended from a high of 0.003322 to a low of 0.003165, with a total volume of 108,102,492.91 and a notional turnover of $289,094 (at mid-range estimate). The pair has shown a clear bearish bias, with price breaking below key support levels into a bear phase.

On the 15-minute chart, key support emerged around 0.003240–0.003260, with a cluster of bearish candlestick formations (including a large bearish engulfing pattern on 19:45 ET) suggesting a breakdown was in play. Resistance levels at 0.003300 and 0.003320 were decisively broken, with the latter acting as a strong ceiling after a brief rally. The 20- and 50-period moving averages both remained above price, suggesting a continuation of downward momentum is probable, though a return to the 0.003270–0.003290 range could test short-term sentiment.

The RSI reached overbought territory at 65 before the breakdown, then sharply declined below 35, reinforcing bearish conviction. MACD turned negative early in the session, with the signal line crossing below the histogram, indicating waning bullish momentum. Bollinger Bands narrowed significantly around 00:30–04:15 ET, followed by a breakout in line with the trend, signaling higher volatility. Price remained in the lower third of the bands for the majority of the session, consistent with a bearish profile.

Volume surged during the breakdown on 19:45–20:15 ET, with a notional turnover of approximately $75,000, reinforcing the move. A divergence was observed between volume and price during the 03:00–06:00 ET period, where turnover declined while price remained under pressure—this may suggest a potential exhaustion phase. Fibonacci retracements from the 0.003292–0.003322 swing align with key support levels at 0.003275 (38.2%) and 0.003248 (61.8%), both of which saw some buying interest but failed to hold.

In the coming 24 hours, the price of COSUSDT may test support at 0.003210–0.003205, with a breakdown risking a move toward 0.003170. A return above 0.003275 could trigger short-term buying interest, but the broader bearish bias appears intact. Investors should watch for volume confirmation at key levels and divergence in the RSI.

Backtest Hypothesis
The backtesting strategy under consideration involves entering a short position when the 50-period moving average crosses below the 200-period moving average (death cross) and the RSI drops below 50, with a stop-loss placed at the nearest Fibonacci retracement level. This approach is supported by today’s move, as both indicators signaled a bearish shift. A trailing stop could be added as price approaches the 0.003275–0.003290 range to capture potential short-covering rallies. Given the strong volume and turnover confirmation, the strategy appears well-aligned with recent price dynamics.
