CryptoFlow by lag0

TradingLite Alternative Liquidity heatmap and footprint in the browser, free.

TradingLite's service has ended, and its homepage now says the previous service will not resume. If you used it to watch resting liquidity and executed volume in a browser tab, CryptoFlow by lag0 covers that core workflow for BTC, ETH and SOL perpetual futures. It is free, needs no install and opens without an account. It is not a full replacement: there is no scripting language and far fewer markets.

CryptoFlow liquidity heatmap on a Bitcoin perpetual chart: resting order-book bands behind the candles, absorbed-trade labels and a volume profile on the right
The CryptoFlow heatmap draws resting limit orders behind the candles. The volume profile on the right answers a different question: where volume actually traded.

What happened to TradingLite

TradingLite was a browser-based order-flow platform. Its homepage now reads "service ended" and offers the technology for acquisition. We could not find a published shutdown date; the page itself dates the product 2018–2026.

The service

By its own description, TradingLite combined a GPU-rendered liquidity heatmap, a footprint and volume-profile suite and its own scripting language for indicators, fed by data from more than a dozen exchanges. Its chart, login and pricing pages no longer load.

The technology

The source code, the scripting language and interpreter and the chart and heatmap rendering engine are listed for sale as a standalone asset. User accounts, customer data and the operating business are not part of that sale.

Former subscribers

The page says it takes no payments and holds no account records. Billing questions belong with the former operating company, or with your card issuer if you were charged for a period without service. lag0 is not affiliated with TradingLite and cannot help with old accounts.

What TradingLite users need now

Most people looking for a replacement want the same three views in one browser tab, without installing desktop software and without rebuilding their whole routine.

A liquidity heatmap

Resting limit orders drawn behind price, so you can see where size sits and whether it holds, gets pulled or gets absorbed. CryptoFlow's heatmap and order book come from Binance USDT-M futures depth.

A footprint chart

Bid and ask volume per price level inside each candle, with delta and CVD below the chart. CryptoFlow builds its candles and footprint from Bybit USDT perpetual trades, and the two sources stay labeled in the app.

A volume profile

Where volume actually traded, with point of control and value area for the current and the previous session. VWAP, big-trade markers and stacked-imbalance markers sit on the same chart.

TradingLite vs CryptoFlow by lag0

TradingLite as it was described before the shutdown, next to CryptoFlow today. The TradingLite column comes from its own homepage and public listings; where we could not confirm a feature, the table says so.

When lag0 is not the right fit

TradingLite did more than lag0 in some areas. If one of these matters to you, another tool will serve you better.

Look elsewhere if you need

  • Your own indicators or scripts: lag0 has no scripting language
  • Altcoins beyond ETH and SOL, spot markets, stocks or forex
  • Volume from many exchanges merged into one footprint: lag0 builds its footprint from Bybit trades
  • Buy or sell instructions: lag0 is a research tool, not investment advice

lag0 fits if you want

  • Heatmap, footprint, CVD and volume profile for BTC, ETH or SOL perpetuals in one browser tab
  • To start without an account, a card or a download
  • Each view labeled with the exchange it comes from
  • Replay of past sessions and an AI second opinion with a free account

How to switch in 2 minutes

There is nothing to migrate. Your TradingLite layouts and scripts will not carry over, so start from the default layout and add views one at a time.

  1. Open lag0.io in any modern browser. The live chart loads without an account.
  2. Pick the coin in the market menu at the top: BTCUSDT, ETHUSDT or SOLUSDT.
  3. Turn on the heatmap with the H key, or under Indicators, Order flow.
  4. Set the tick size in the Tick menu above the chart, so footprint cells group enough volume to read clearly.
  5. Optional: create a free account to unlock replay of past sessions and more AI Analyst scans.

FAQ

Is TradingLite still working?

No. The TradingLite homepage now says the service has ended and that the previous service will not resume. The site only offers the technology for sale; its chart and login pages are gone.

Is there a free alternative to TradingLite?

Yes. CryptoFlow by lag0 is free and runs in the browser, with a liquidity heatmap, footprint chart, volume profile, delta and CVD. It covers only BTC, ETH and SOL perpetual futures and has no scripting language.

Does lag0 have a liquidity heatmap like TradingLite?

Yes. CryptoFlow draws resting limit orders from the Binance USDT-M futures order book behind the chart. Press H, or open Indicators and then Order flow, to turn it on. It shows displayed liquidity, not executed trades.

Do I need to install anything?

No. CryptoFlow runs in a modern browser on desktop or phone. The live chart opens without an account; a free account adds replay and more AI Analyst scans.

Can I use my TradingLite scripts in lag0?

No. lag0 has no scripting language, so custom TradingLite indicators cannot be imported or rebuilt. The built-in views cover heatmap, footprint, delta, CVD, volume profile, VWAP and impact zones.

Try the heatmap and footprint in your browser.

Free, no install and no account for the live chart. Pick BTC, ETH or SOL, then press H for the heatmap.
