What should I know about using an Expert Advisor?

Before you start using an EA, ask yourself, can you trust a pure black box with thousands of dollar in capital? Does this idea sit well with you? If the answer is yes, then learn as much as you can about your EA. Don’t rush into things. Knowledge is power. Knowing why an EA trades and how it works can be the critical factor that convinces you to stick with a winning strategy during a drawdown. You always have the ability to turn the EA off. You are likely to do just that if you don’t know why you are losing money.
IMPORTANT! Always read the manual that comes with your EA.
