EAs and cBots allow you to automate your trading.
There are many advantages to automating your trading. Firstly, algorithmic trading eliminates the stress and anxiety that usually come with trading manually and is therefore not prone to mistakes made on impulse when the market moves unfavourably. Secondly, trading with EAs/cBots can significantly reduce the time you spend waiting for the perfect trading opportunity since your trading algorithms monitor the market, identify good opportunities and execute trades for you. Thirdly, all calculations are carried out by algos, which increases the accuracy of your trades.
