Ever since the clock first struck midnight turning into the new year, altcoins like XRP, Ethereum, Litecoin, and many others have been tearing up the price charts and going on massive price rallies. But those rallies have now triggered a sequence of candlesticks that according to a world-renowned market analyst typically result in a reversal and selloff following. XRP, Ethereum, and Litecoin Trigger TD9 Sell Signal On Sequential Indicator Towards the start of 2020, the total cumulative altcoin market cap and a number of individual altcoins broke out from downtrend resistance, including large-cap cryptocurrencies like XRP, Ethereum, and Litecoin.

But before that happens, anyone who bought the recent altcoin bottom may have to hold through a strong retracement first. According to the TD Sequential Indicator, created by financial market whiz Thomas DeMark, each of the three aforementioned altcoins – XRP, Ethereum, and Litecoin – have all reached a 9 “sell” signal on daily timeframes after a series of positive candle closes. The sell signals appear on XRP/USD, ETH/USD, and LTC/USD. However, the three major altcoins aren’t alone in triggering sell signals on daily timeframes. Cardano and Monero both also triggered TD 9 sell signals on their USD pairs, while Cardano and Litecoin also triggered TD 9 sell signals on their BTC trading pairs as well. Return of Alt Season Postponed, But Retracement Could Be Bullish All this week, the ongoing rallies have resulted in a number of crypto analysts reviving talk about an upcoming alt season. And while it cannot be ruled out at this point, alt season may be canceled or at the very least postponed until after a retracement occurs. Even a fall from current levels would likely be extremely bullish, so long as former resistance confirms as support and holds strong. A confirmation of resistance turned support would likely lead to even more confidence in bullish crypto investors, and could put the final nail in the bear market coffin.
