Metatrader4, Metatrader5, or some other options?
Both MetaTrader 4 and MetaTrader 5 are products of the same company - the leading developer of trading software, MetaQuotes Software Corp.
MetaTrader5 is the latest generation trading platform, which is in fact a revised version (taking into account modern requirements) of the MetaTrader4 platform.
The MetaTrader5 trading terminal is more flexible and adaptive and has a modern architecture. Due to this, many brokers offer better trading conditions for users using this platform.
In reality, the choice is much wider. Despite the popularity of these two options, it would be wrong to choose only from these two platforms. The most rational approach is to fully compare all existing solutions using any financial solutions aggregator. This way you could evaluate your options and see what suits you best.
