# Data (/platform/charts/data)



Charts use **LuxAlgo market data**: candles plus a live stream, delivered by one provider that sits in front of several venues. You don't connect exchange accounts or API keys.

**Free** covers crypto and US equities (including ETFs). **Premium**, **Ultimate**, and **AI Ultra** add forex, commodities, and CME futures.

There are two kinds of data behind the chart, and they matter for which tools run where:

* **Candles**: OHLC and volume per bar. Every market has them, and everything candle-based (chart types, most indicators, TPO, VWAP, Visible Range Volume Profile) works everywhere.
* **Footprints**: 1-minute slices of volume-at-price **and** per-side trade counts. Only some venues provide them, and only the tools that need them are restricted. A footprint is *not* a trade tape or an order book; it's a pre-aggregated summary of executed volume at each price.

## Venues [#venues]

| Market      | Sources                                                     | Order flow                     | Plans      |
| ----------- | ----------------------------------------------------------- | ------------------------------ | ---------- |
| Crypto      | Binance (spot and perps), Binance.US, Coinbase, Hyperliquid | Yes: pre-aggregated footprints | Every plan |
| US equities | Cboe EDGX                                                   | Yes: pre-aggregated footprints | Every plan |
| Forex       | Spot FX                                                     | Candles only                   | Paid       |
| Commodities | Commodities feed                                            | Candles only                   | Paid       |
| Futures     | CME                                                         | Candles only                   | Paid       |

Open **Symbol Search** from the topbar (tabs: **All**, **Stocks**, **ETFs**, **Crypto**, **Futures**, **Forex**, **Commodities**). To pin a specific venue rather than the default resolution, use the `PROVIDER:SYMBOL` format, e.g. `binance:BTCUSDT` charts Binance spot specifically.

## What runs where [#what-runs-where]

[Order Flow](/platform/charts/order-flow/introduction) tools that need footprints only run on crypto and US equities. On forex, commodities, and futures those tools **warn** instead of silently drawing a blank series, so a missing plot always has an explanation.

Three order-flow-family tools are exceptions because they're computed from candles: **TPO**, **VWAP**, and the **Visible Range Volume Profile** work on every market.

## Sessions [#sessions]

Where a symbol has a trading calendar (US equities, for example), the bottom bar can switch between:

* **RTH**: regular trading hours, the main session only.
* **ETH**: extended trading hours, including pre-market and after-hours activity.

The choice affects what the chart shows and therefore everything computed from it. Session-based tools like TPO read differently on RTH vs ETH.

## History limits [#history-limits]

How much history a chart can load depends on your plan, measured in bars (so a lower timeframe covers less calendar time):

| Plan     | Bars of history |
| -------- | --------------- |
| Free     | 5,000           |
| Premium  | 20,000          |
| Ultimate | 30,000          |
| AI Ultra | 50,000          |

Footprint history has its own, separate limits by plan. See the note in [Order Flow](/platform/charts/order-flow/introduction).
