High quality tick data is essential for proper Forex testing and practicing.
Our Forex Simulator only uses tick-by-tick data for simulations.
We use high quality historical market data provided by TrueFX.
The data is free and is available for 15 main currency pairs since 2009.
You can use any other source of data, but you need to make sure they are presented in the same format TrueFX uses (sample one-day tick data file).
You can also download our tools for editing the tick data files.
