Does a trader need Expert Advisors?

Coped with the trading terminal and strategy it is time to launch further study of trading terminals’ potential particularly MetaTrader4. This terminal in addition to the trading instruments for orders management also provides opportunity of advisors and indicators development with the help of MQL4 language which was included in basic package of the program.

Anyway it is better to secure yourself – check the system in DEMO account or at the history of any currency pair. So answer to the question “Does a trader need Expert Advisor” is being formed by the trader himself/herself depending on his/her experience, free time and skills of using this instrument.
