Renowned cryptocurrency analyst Ali Martinez has spotted a buy signal for SEI, one of the 5 altcoins that analysts believe matter for an August bull run. The signal has appeared on the 4-hour chart for SEI’s perpetual contract, pointing to a rebound on the horizon. In his latest post on X, Martinez highlighted that the signal comes from the Tom DeMark (TD) Sequential indicator. According to the analyst, this specific indicator has been “spot-on” in predicting every major SEI move over the last three weeks, lending significant weight to its latest signal. Every $SEI move in the last 3 weeks was spot on by the TD Sequential… And now the signal says BUY! pic.twitter.com/8Me9sDRG01 — Ali (@ali_charts) August 20, 2025 A powerful indicator in line with SEI’s trend For context, the TD Sequential is a financial market analysis tool developed by Tom DeMark to identify potential reversals. The technical indicator functions in a two-phase process: Setup and Countdown. It analyzes price sequences and pinpoints exhaustion points. Those are the regions where trends end and the market changes direction. Martinez’s latest highlight suggests an end to a downtrend that has lasted for the past seven days. It is a pullback that saw SEI decline from $0.3640 to $0.2958, reflecting an 18.5% pullback within one week. Despite this recent dip, SEI remains in a broader uptrend, having previously rallied even in the face of Weekly Token Unlocks. TradingView’s data shows that the cryptocurrency has gained over 200% since the beginning of Q2 2025. However, the latest pullback leaves the profit at 130%, even though the bullish momentum remains intact. Crucial alignment with Fibonacci Retracement SEI traded at $0.3 at the time of writing, coinciding with the 0.382 Fibonacci retracement on its daily chart. A combination of the Fibonacci support and the TD Sequential boosts the confidence of traders who believe in Martinez’s idea of an upcoming trend reversal. However, cautious traders would investigate a potential break below this level, which could lead to a further decline in the SEI price. Breaking below the current support would open the way for SEI’s price to head toward the 0.5 Fibonacci level, coinciding with $0.2744. Nonetheless, the trend remains bullish, and Martinez expects the price to reverse and SEI to move to higher levels.
