When you begin as a trader it’s all foreign. With time of course it all becomes second nature. Don’t be scared of breaking anything. If you place a trade in a real account simply close it by clicking the x in the terminal window. Ideally play for a few days in demo and learn as fast as possible. Place trades, let them run, set profit, set stops. If you blow up the account start another one. They run for 30 days if you don’t blow them up!
A great resource is the Go Markets YouTube channel or any other Youtube channel. Simply search for the problem you need answering.
