Three altcoins are flashing bearish technical signals as NEAR Protocol, privacy-focused Zcash (ZEC), and BNB, the native token of the BNB Chain ecosystem, each face critical support tests. Market analyst Ali Charts identified sell signals across the three assets using the TD Sequential, Parabolic SAR, and SuperTrend indicators, noting that each signal has preceded a substantial correction in a previous comparable setup. Past price movements, however, do not guarantee similar outcomes this time. The readings arrive after each asset has already logged a notable pullback, and traders are now watching key support levels for signs of whether the declines will deepen.

NEAR Sell Signal Puts $4.30 and $3.76 in Focus

According to Ali Charts, NEAR's weekly TD Sequential indicator, a timing tool that flags potential points of trend exhaustion, has flashed a sell signal. The last comparable signal preceded a 32% correction. NEAR has already fallen 24%, with $4.30 identified as immediate support and the $3.76 area positioned as the next level below it.

Not every market participant is leaning bearish on the longer-term picture. Analyst Giannis Andreou highlights a longer-term bullish structure, saying NEAR has broken above a falling trendline stretching back to its 2022 peak. He notes that the breakout preceded a rally toward $6, while $3.73 remains the key level buyers must defend. If NEAR holds that support, Andreou identifies $7.60 as the next major resistance. The $9 region represents a potential neckline for a multi-year double-bottom pattern, and a confirmed breakout above that neckline could strengthen the case for a move toward $20.59. Losing $3.73, however, would weaken the bullish structure.

Zcash's Parabolic SAR Flips Bearish as ZEC Tests $1,100

Zcash faces a separate warning from its Parabolic SAR indicator, a trend-following tool whose dots have moved above the price, suggesting bearish momentum. Ali Charts notes that the previous bearish flip preceded a 54% retracement. ZEC has already pulled back 25%, with $1,100 under test and $850 seen as the next downside level traders are monitoring.

Analyst Ardi offers a broader interpretation of Zcash's price action. He describes the pullback as mean reversion following an overheated rally toward $1,600. Under this framework, prices can retreat toward their historical average before consolidating or attempting another advance.

BNB SuperTrend Sell Signal Puts $710 Support at Risk

BNB's daily SuperTrend indicator a trend-following gauge that switches between buy and sell readings as price crosses its bands, has also flipped to a sell signal, according to Ali Charts. The previous comparable flip preceded a 26% decline, while BNB has fallen 8% so far — the shallowest of the three pullbacks in focus. Ali identifies $710 as support and flags $680 as the next downside level if buyers fail to defend it.

CoinGecko data puts BNB at $713.73, down 0.98% over 24 hours and 4.67% over seven days. Its reported daily trading volume stands at $504.96 million, providing additional context for the ongoing pullback.

Analyst Don Wedge identifies a falling wedge on BNB's daily chart following its $1,370 peak. Price faced rejection near the upper boundary around $800 and subsequently retreated toward $730. He places the lower wedge boundary near $540, with a daily close above the upper trendline potentially targeting $1,601.

Scenarios, Not Confirmations

These technical readings present different scenarios rather than confirmed price outcomes. Sell signals suggest caution, but support breaks would provide stronger evidence of further downside. Support levels carry weight here because they mark zones where buying interest has previously slowed declines, which is why their defense or loss serves as the clearest near-term test of each bearish reading. For traders, the immediate focus remains on whether NEAR holds $4.30, ZEC defends $1,100, and BNB maintains $710. All three altcoins face bearish technical warnings, but their next moves depend on how price responds at these critical support levels.
