Binance – Crypto Tools & Alert Real-time crypto prices & powerful trading tools & alerts Live Binance Spot prices with RSI, 24h% and EMA Trend - plus cross-based Price Alerts. Fast, compact, privacy-friendly. No login. No tracking. What's new (v3.0.0) Binance Alpha (AP) support: Alpha is now a first-class market alongside Spot and Futures. AP symbols work across Live Prices, Price Alerts, Auto Alerts, Custom Alerts, charts, and Alert History. Autocomplete shows clean symbol names while keeping raw IDs internally. "Open on Binance" is chain-aware for Alpha tokens. AP data source selector: Added On-Chain, Limit, and On-Chain+Limit modes for Alpha. The selection is respected for AP prices, 24h stats, and klines, and the AP offscreen REST engine has its own cadence/backoff controls to reduce rate-limit risk. News Alerts (RSS + keywords): Added multi-source RSS pipeline (Coindesk, Cointelegraph, etc.) with per-source toggles, refresh interval control, and a new "Only headline hits" mode that fires alerts only when the title contains your Headline keywords. Headline highlighting is applied in the popup, and notifications include source + title + quick link. Works with the popup closed (offscreen/worker). Mini charts from Live Prices: Clicking a timeframe badge now opens a lightweight mini chart window (candles, hover tooltip with OHLC, current price line). Uses cached/pushed table data to avoid extra API load; supports per-TF chart opening and respects your popup data cadence. One-click "Disable Alert" in notifications: Price/Auto/Custom alert notifications now have a button to disable that alert immediately. For Auto alerts, it respects per-TF customization when enabled; for Custom/Price alerts, it toggles the specific alert off and syncs state to storage. Backup/Restore (Full Backup JSON): Export/import every setting (symbols, alerts, builder templates, RSS prefs, UI visibility, advanced thresholds) in one JSON. Useful for migrations, safety copies, or sharing setups. Alert Builder stability & tuning: Custom alerts now load reliably on worker startup; price updates also trigger custom evaluations to keep signals fresh. Builder cards have clearer presets, field-to-field comparisons, and better validation. An About/Help tuning section was added for "How to tune alerts" (Price/Auto/Custom/News) to reduce noise. Options UI refactor: Tabs split into dedicated logic files (Live Prices, Price Alerts, Alert Builder, Alert History, Settings) for stability. Added About tab with legal/privacy links, contact info, and help/guide content. Cleaner defaults and saved-state persistence for collapses and toggles. News & RSS tuning: New sources added; per-source enable/disable, keyword-based filtering, "Only headline hits" toggle, configurable refresh minutes/items per source. Added request spacing and retry logic to mitigate 429/rate limits. Performance & resilience: Improved offscreen/worker coordination; polling/backoff tuned for spot/futures/alpha; klines cache reuse for charts and alerts; reduced duplicate signals; safer handling of missing data (neutral rather than false positives). Charts & tooltips: Mini chart hover tooltip now shows full labels (Open/High/Low/Close) on separate lines; current price line displayed cleanly; layout avoids clipping on large candles. General fixes & polish: Consistent Forecast row behavior, better defaults for checkboxes (Summary row, adaptive cadence), UI cleanups, clarified presets (24h% defaults, Vol spike multipliers, MACD tolerance), and multiple small bug fixes around Alert History formatting and disable flows. Alert History: In v3.0.0 the Alert History was expanded to capture every alert type (Price, Auto, Custom, News) with richer "Actual value" formatting—e.g., Price vs EMA split onto separate lines instead of a single string—while keeping links clickable (news URLs, trade URLs). Clearing the log is instant, and the view auto-updates on storage changes so you don’t need to refresh manually. State changes triggered by "Disable Alert" buttons are respected without removing past entries, and the popup and Options history views stay in sync, showing neutral or missing fields cleanly instead of noisy placeholders. CSP/security hardening: CSP applied to extension pages, reduced inline usage; rate-limit protection (429/5xx retry + per-host delay); schema + size limits on backup/import; max-size guards on alert/history lists to protect storage quotas. InnerHTML reduction/XSS mitigation: Feed titles, imports, and backup loading now rely on textContent/createElement, lowering XSS risk. Always free, no ads, no paywalls, no telemetry. Focused on faster decision support, clearer alerts, and giving you full control over notification volume.

Select an RSI timeframe per row: 1m • 3m • 5m • 15m • 30m • 1h • 2h • 4h • 6h • 8h • 12h • 1d. Grouped (Compact) view: within a symbol group, repeated columns are merged; toggle in the popup footer. Your order, your groups: the popup follows the order you set on Options; TFs inside a group are auto-sorted. Optional columns: 24h Volume (quote), MACD (hist; up to 8 dp for micro moves), ATR% (14), BB width (20,2). Color cues: RSI ≥70 overbought (red), ≤30 oversold (blue).

Price Alerts (cross-based) Build alerts that fire only when price crosses the target (not on every tick), with protection against flicker. Condition: Above (≥) or Below (≤) a target price. On / 1×: per row; One-shot disables itself after the first fire. Hysteresis: tolerance around the target (e.g., 0.02%) - the alert fires only after a real side change.

Price×EMA (20/50/200): price vs EMA crossings with the same filter logic. Volume Spike: open-bar gates to avoid noise - Progress (0–1 of bar time), Min body % (body/range), Persist (ms) (stay above threshold). One-shot per open bar. 24h%: up/down defaults with override per symbol. Global cooldown: prevents repeated fires across all auto alerts. Per-indicator TFs: pick TFs for RSI/EMA/Vol independently (Customize). Empty list = indicator disabled.

Drag (≡) to reorder; popup follows your order and groups by symbol. Compact view (popup footer): denser scan; repeated columns collapse inside symbol groups. Manual alerts: in Price Alerts, add cross-alerts (Above/Below). Set Hysteresis (tolerance), Min repeat (cooldown), Style (Badges default), Mute if needed → Save. Auto Alerts (Settings): – Turn on what you need (RSI, EMA cross, Price×EMA, Volume Spike, 24h%). – Pick per-indicator TFs (Customize). Empty list = indicator OFF. – Choose EMA filter (none / separation / separation+hold / full). – Optional Closed-bar mode (alerts on the last closed candle only). – Set Global cooldown (ms) to avoid repeats. Expand (top-right) pops the table into a large window for desk-view usage.

Background REST engine: when the popup is closed, an offscreen page polls Binance REST with the same cadence as the popup; FT backoff (429 + jitter + concurrency), optional SP backoff, and Adaptive cadence (SP & FT) keep it rate-limit friendly; a heartbeat restarts it if needed. Local cache: Market Pulse uses short TTL caches; Live Prices uses small in-memory/local caches for indicators to minimize API calls. Robustness: invalid/unsupported rows show “—”; others continue to update. Tabular digits + fixed min widths reduce visual jitter. Privacy & permissions No login. No tracking. No trading.
