Several altcoins are flashing interesting technical signals on the 30-minute chart right now. RSI overbought and oversold conditions have emerged across multiple pairs—STO, MERL, RARE, ACE, SENT, THETA, MEW, YB, DOLO, SUPER, ICNT, ASTR, HFT, DEGO, GTC, IOTX, SOON, TRX, TREE, and ALLO are all showing notable extremes.

When RSI breaks above 70, you've typically got an overbought scenario—potential pullback territory. Below 30? That's oversold, which sometimes flags reversal opportunities. On shorter timeframes like 30 minutes, these readings can be whipsaws though, so context matters. Pair these signals with support/resistance levels and volume confirmation before pulling the trigger. Worth monitoring which ones hold or reverse.
