Crypto Live Radar

Checking whether Bitcoin, Ethereum, or Solana is stretched into overbought (RSI > 70) or oversold (RSI < 30) territory on a specific timeframe shouldn't require logging into a heavy exchange terminal cluttered with order books and margin popups. This live crypto chart and RSI scanner connects directly from your browser to public Binance WebSocket streams and embeds an interactive TradingView chart - computing real-time 14-period Wilder Relative Strength Index (RSI-14), 24-hour high/low/volume stats, and regime signals with zero account login.

When traders and analysts want a clean, zero-login market pulse

Full cryptocurrency exchange interfaces are built for placing leveraged orders - loading dozens of panels, wallet notifications, and popups that obscure the actual price action and momentum readings:

• Checking multi-timeframe RSI momentum before entering a trade: Switching rapidly between 1m, 5m, 15m, 1h, 4h, and 1d candle intervals on BTC/USDT, ETH/USDT, SOL/USDT, or BNB/USDT to see if a short-term dip on the 15-minute chart aligns with an oversold reading (RSI < 30) on the 4-hour chart.
• Keeping a lightweight live ticker open on a second monitor: Streaming sub-second WebSocket kline updates with live 24-hour percentage change, 24h peak/trough, and USDT volume without running an authenticated session that could time out.
• Drawing trendlines and inspecting full technical indicators: Using the integrated TradingView advanced chart workspace alongside the dedicated RSI-14 regime gauge (Oversold < 30, Neutral 30–70, Overbought > 70).
• Understanding exact Wilder RSI math on live closes: Inspecting the exact 14-period smoothed average gain vs average loss calculation directly from the latest historical kline closes.

Monitoring live crypto price action and RSI step by step

1. Select your trading pair: Choose BTC/USDT (Bitcoin), ETH/USDT (Ethereum), SOL/USDT (Solana), or another supported major pair in the top asset bar.
2. Pick your candle timeframe: Switch the interval selector between 1m, 5m, 15m, 1h, 4h, or 1d depending on whether you are scalping intraday swings or watching daily trend structure.
3. Read the live RSI-14 Momentum Gauge: Check the numeric RSI readout (0–100) and regime badge (Oversold (<30), Bullish/Bearish Neutral (30–70), or Overbought (>70)) updated in real time as each WebSocket tick arrives.
4. Analyze the interactive chart: Use the full TradingView canvas to inspect candlestick patterns, moving averages, volume bars, and support/resistance levels.

How the live WebSocket stream and Wilder RSI-14 formula work

Direct browser-to-Binance WebSocket (wss://stream.binance.com:9443) feed

Instead of polling a delayed caching server every 60 seconds, your browser opens a direct WebSocket subscription to the official public @kline_<interval> and @ticker streams. Every price tick updates the current candle close and recalculates the live momentum gauge with millisecond latency.

Authentic J. Welles Wilder 14-Period RSI Smoothing

Many basic scripts compute RSI using a simple moving average (SMA) of the last 14 bars, which produces numbers that do not match TradingView or exchange charts. Our engine implements Wilder's exponential smoothing (RMA) across historical klines:

1. Seed initial 14-period Average Gain (AvgGain_14) and Average Loss (AvgLoss_14).
2. For each subsequent candle close change Δ = Close_t - Close_{t-1}:

• AvgGain_t = ((AvgGain_{t-1} × 13) + CurrentGain) / 14
• AvgLoss_t = ((AvgLoss_{t-1} × 13) + CurrentLoss) / 14

1. Compute Relative Strength RS = AvgGain_t / AvgLoss_t and:

• RSI = 100 - (100 / (1 + RS))

Automatic regime classification (30 / 50 / 70 thresholds)

The gauge translates raw RSI numbers into clear visual states:

• Oversold (RSI < 30): Selling momentum has been heavily one-sided over the past 14 bars; watch for potential mean-reversion bounces or exhaustion.
• Neutral (30 ≤ RSI ≤ 70): Balanced two-way trading (with 50 acting as the centerline between net bullish and net bearish momentum).
• Overbought (RSI > 70): Buying momentum is extended; watch for profit-taking pullbacks or strong breakout continuation.

A real example: calculating 14-period RSI on a 1-hour Bitcoin (BTC/USDT) surge

Suppose over the last 14 one-hour candles on BTC/USDT, the smoothed Wilder average hourly gain is AvgGain = $310.50 and the smoothed average hourly loss is AvgLoss = $112.00, and the current live 1-hour candle is up another +$420.00 (CurrentGain = 420, CurrentLoss = 0):

1. Updated Smoothed Average Gain: ((310.50 × 13) + 420.00) / 14 = (4036.50 + 420.00) / 14 = $318.32
2. Updated Smoothed Average Loss: ((112.00 × 13) + 0) / 14 = 1456.00 / 14 = $104.00
3. Relative Strength (RS): RS = 318.32 / 104.00 = 3.0608
4. Live RSI-14 Value: RSI = 100 - (100 / (1 + 3.0608)) = 100 - (100 / 4.0608) = 75.37
5. Because 75.37 > 70, the scanner highlights Overbought (75.4) on the 1h timeframe, warning you that chasing a market buy at the top of the hourly candle carries elevated pullback risk.

Practical tips, mistakes, and market disclaimers

• "Overbought" does not mean "Short immediately": In a strong parabolic breakout, RSI can remain above 70 (or below 30 in a crash) for many consecutive candles. Always check higher-timeframe trend structure and volume rather than trading a single indicator in isolation.
• Informational utility, not financial advice: All live prices, RSI calculations, and regime labels are technical math readouts provided strictly for educational and informational monitoring - never automated buy or sell recommendations.

Privacy and external data feeds

This tool requires zero account registration, wallet connection, or personal data. To display live market prices and charts, your browser connects directly to Binance's public market data endpoints (api.binance.com and wss://stream.binance.com:9443) and loads the official TradingView widget script (s3.tradingview.com/tv.js). No personal or financial user data is collected or transmitted.

Comparing RSI timeframe horizons and divergence patterns

Because the 14-period Wilder RSI looks back exactly 14 bars of whichever timeframe you select, its meaning shifts from microstructure noise to macro cycle positioning:

• Scalping & intraday intervals (1m, 5m, 15m): Reacts within minutes to order-book sweeps and liquidation wicks. Traders watch for brief spikes above 75 or flushes below 25 around key support/resistance levels.
• Swing trading intervals (1h, 4h): Filters out 1-minute noise and highlights multi-day momentum waves. A bullish divergence - where Bitcoin prints a slightly lower price low (e.g., $64,200 → $63,850) while 4-hour RSI prints a higher low (24.1 → 31.8) - signals that downward selling pressure is decelerating.
• Daily macro view (1d): Tracks 14 full UTC trading days (2 weeks). Daily RSI readings below 30 historically occur only a few times per year during major market-wide capitulation events.
