LiqSonar is a real-time analytics and alert service for crypto futures. It tracks whale trades, liquidations, order-book walls, pumps and dumps, open interest and funding across 522 Binance USDT-M futures pairs and the largest pairs on Bybit, OKX, Bitget, MEXC, Gate and Hyperliquid, and sends alerts in the browser, by email or in Telegram. ### Who is LiqSonar for? For traders of altcoin and major crypto futures who want to see what large players do before it shows on the chart: whales opening positions, leveraged traders being liquidated, walls appearing in the order book and pumps that nobody is actually buying. ### Which exchanges and markets does LiqSonar cover? Binance USDT-M futures in full (522 pairs), plus Bybit, OKX, Bitget, MEXC, Gate and Hyperliquid. Data is collected directly from the exchanges in real time: trades, liquidations, order books, open interest and funding. ### Is LiqSonar free? Yes, the Free plan is free forever and needs no card. Every new account also gets 3 days of Pro for free. Pro costs $9 per month or $79 per year. ### Do I need Telegram to use LiqSonar? No. You can sign up with email, use the whole app in the browser, get alerts as browser notifications or emails and pay for Pro on the site. The Telegram bot is an optional extra channel. ## Features ### What is a whale trade alert? An alert for a single futures trade over $800K or a liquidation over $300K, sent the moment it happens, with a chart that shows what came before it and how buying and selling changed. ### What is the liquidation map? An estimate of the price levels where leveraged longs and shorts would be liquidated, in USD per price level within ±12% of the current price. Price is often drawn to these clusters. Free shows BTC and ETH for 1 day; Pro shows any pair for up to 7 days. ### What is the order-book heatmap and the walls screener? The heatmap shows resting limit orders over time, so you can see walls form, move and disappear. The walls screener lists unusually large orders (at least $50K and 8 times the median order within 5% of the price) across Binance, Bybit and OKX. You can get an alert when price comes near a wall. ### What does "manipulation or organic" mean? LiqSonar compares the price move with real buying and selling (CVD) across Binance, Bybit, OKX, MEXC, Bitget and Gate. If price rises while nobody is actually buying, the move is flagged as likely manipulation. ### How does the pump detector work? It finds pumps and dumps on every futures pair and gathers what happened around them: volume, open interest, funding, liquidations and order-flow signals. An AI breakdown explains the event in plain language. Free shows pumps from the last 7 days; Pro has the full history with AI breakdowns. ### Which order-flow signals does LiqSonar send? CVD divergences, CVD breakdowns, recoveries and flips, short and long squeezes, buy and sell absorption, buying and selling pressure, overheated or exhausted funding, volume spikes, large liquidations and whale trades. ### Can I set my own alerts? Yes: on a price level, a price move, open interest, volume, funding or a price approaching an order-book wall. Free allows 2 alerts, Pro up to 20. ### What does the AI analysis do? It writes a short analysis of any coin from all LiqSonar data at once: order flow, open interest, funding, liquidations and walls. It describes the data and does not give entries, stops or trade recommendations. Free includes 1 analysis per day, Pro 20. ### Does LiqSonar compare funding and open interest across exchanges? Yes. The Longs/shorts tab shows open interest and funding on Binance, Bybit, OKX and Hyperliquid for a coin, and the funding comparison shows current funding for every coin on all four exchanges scaled to 8 hours, with the gap between them. ## Plans and payment ### What is the difference between Free and Pro? Free: signals for the top 20 pairs with a 15-minute delay and up to 3 per day, pumps from the last 7 days, the Binance verdict for every pair, and the heatmap, liquidation map and other exchanges for BTC and ETH. Pro: every signal for all 522 pairs instantly, the verdict, heatmap and liquidation map for any pair, full pump history with AI breakdowns, more AI analyses and the API. ### How do I pay for Pro? On the pricing page press "Pay with crypto" and pay the invoice in USDT, BTC, ETH, USDC, TON, TRX or another supported coin. Pro switches on automatically once the payment is confirmed. If you signed in with Telegram, you can also pay inside the bot with /pro. ### Will I be charged automatically? No. You pay for a month or a year in advance and there is no auto-renewal. A renewal adds time to your current end date. ### Is there a referral program? Yes. Share your invite link; when someone you invited pays for Pro, you get 30 days of Pro. ## Data and API ### Where does the data come from? LiqSonar connects directly to the exchanges’ public APIs and WebSocket streams and stores the history itself. It does not resell third-party data. ### Is there an API? Yes, the API is part of Pro: pumps, liquidation levels, order-flow signals, order book walls and the cross-exchange verdict as JSON, 60 requests per minute per key. See the API documentation. ### Can I connect LiqSonar to Claude, ChatGPT, Cursor or another AI assistant? Yes. LiqSonar runs an MCP server at /mcp as part of Pro. In claude.ai, Claude Desktop or ChatGPT add it as a custom connector and sign in to LiqSonar, no key needed; Claude Code, Cursor and other MCP clients can sign in the same way or use the Pro API key, and the assistant can pull signals, pumps, liquidation levels, walls, the verdict and your own alerts and watchlist while you ask about the market in plain words. Ready-to-paste settings are in the API documentation. ### Is LiqSonar financial advice? No. LiqSonar provides market data and analytics. It does not tell you what to buy or sell. Trading crypto derivatives carries a high risk of losing all of your capital.
