US stocks and ETFs
Every equity listed on NYSE, NASDAQ, and AMEX, roughly 13,000 tickers, including ADRs (US-listed shares in a foreign company) and recently listed names. All US-listed ETFs are covered on the same footing; an ETF is a fund that trades like a single stock. Price data comes from the SIP feed, the consolidated tape that merges quotes from every US exchange, so you are seeing the national best bid and offer rather than one venue’s view. Bars are available at 1, 5, 15, and 30 minutes, 1 hour, and daily, weekly, and monthly.Crypto pairs
Around 40 pairs, all quoted against the US dollar, BTC/USD, ETH/USD, SOL/USD and so on down through the mid-caps. Crypto markets run 24/7, so there are no closed hours. The available list changes as the data provider adds and removes pairs. If a pair does not appear in the symbol search, Tradion cannot reach it.Forex pairs
Around 20 currency pairs: the majors (EUR/USD, GBP/USD, USD/JPY and the rest), common crosses such as EUR/GBP and GBP/JPY, and a handful of exotics like USD/MXN and USD/TRY. Forex trades 24/5, from Sunday evening to Friday evening US Eastern time, and closed at weekends. Forex has no central exchange, which has two consequences worth knowing before you build anything: there is no consolidated volume figure, and Tradion’s forex history is daily only.Options
All OPRA-listed US equity and ETF options. OPRA is the consolidated feed that carries every US listed options quote, so anything with a listed contract is reachable, weekly and monthly expirations alike. Each contract in a chain carries strike, expiry, call or put, bid and ask, volume, open interest (contracts currently held open), implied volatility (the size of move the option’s price implies, rather than movement measured from history), and the five greeks, standard numbers describing how an option’s price reacts to a move in the stock, to time passing, and to volatility changing. Historical options bars start from February 2024; before that, analysis falls back to theoretical pricing.Which features support which asset types
Tradion Lens charts US stocks and ETFs only. Its ticker search lists nothing else, so a crypto pair, a forex pair or an options contract can’t start a session. The Lens chat can still answer questions about a stock’s options chain.
Extended hours and overnight
Outside regular trading hours the price feed returns the last known price, which is the official close once the session ends. For US stocks the feed includes pre-market and after-hours prints (trades outside the 9:30am to 4:00pm Eastern regular session). That is useful during an earnings gap and misleading on a thin ticker, where a single odd print moves the last price. Crypto is continuous. Forex has a weekend gap; nothing updates between Friday evening and Sunday evening US Eastern time.What isn’t supported
Named plainly, so you do not go looking:- Non-US listings. Shares listed only in London, Toronto, Tokyo, or anywhere outside the three US exchanges. A US-listed ADR of the same company is covered.
- Futures. No futures contracts, and no continuous futures series.
- Bonds and commodities directly. Reachable only through US-listed ETFs that hold them.
- Crypto pairs that do not quote in USD. Everything is priced against the dollar.
- Forex volume and forex indicators. Covered above, no consolidated volume exists to compute them from.
- Fundamentals, earnings, insider filings, and corporate actions for anything other than stocks and ETFs. Crypto and forex have no filings to read.
- Order placement. Tradion reads your brokerage and produces analysis. It never sends an order, cancels one, or moves money.
