Real-Time Data for Trading
Why live prices matter: anyone working with delayed prices isn’t analysing the current market, but the past.
Whether day trading, swing trading, futures or automated systems – up-to-date market data enables faster reactions, more precise entries and better-informed decisions.
What is real-time data?
Real-time data is market prices transmitted directly from the exchanges to your trading software without relevant delay. This includes:
- Stock prices
- Futures prices
- Forex data
- ETF prices
- Indizes
- Commodity prices
- Cryptocurrencies
- Warrants and certificates
Unlike delayed prices, you receive market movements immediately as they happen.
Why real-time data is indispensable today
The speed of the financial markets has increased massively in recent years.
A few seconds of delay mean that
- entry signals are recognised too late
- breakouts are missed
- stops are placed incorrectly
- opportunities are lost
A reliable basis for
- short-term trading & day trading
- futures and stock trading
- automated strategies
- real-time market monitoring
