Buy signals for Ethereum and ADA appeared on the 3-day chart

Ethereum (ETH) and Cardano (ADA) have flashed TD Sequential buy signals on their 3-day charts, with a similar setup forming on Solana (SOL), according to analyst Ali Martinez. The signals follow a market pullback triggered by a $6.3 billion Binance hack and elevated volatility around the U.S. midterm elections, after which several altcoins staged V-shaped recoveries over the past 24 hours. TD Sequential is a technical indicator used to identify potential trend-reversal points, and the 3-day timeframe aggregates three days of price action into a single candle. The appearance of buy signals on higher-timeframe charts matters because it suggests selling pressure may be exhausting, though confirmation depends on whether price actually reverses. Traders will watch whether ETH, ADA and SOL follow through with sustained upside in the coming sessions or whether the signals fail amid lingering macro and exchange-related risk.
