If you’re a newbie in forex trading, you shouldn’t try to utilize an EA first because markets change all the time, rendering the EA useless.
Almost all EAs need an initial purchase, followed by hosting to keep it running 24/7. As a result, you spend a lot of money without really knowing what you’re getting.
When the market is trending, a trend-following EA will do well, but it will lose a lot of money when the market is range. When the market starts trending, and EA intends to trade ranges will cause whipsaws.
So, if you’re new to trading, I recommend starting with manual trading.
