Hi KattyKH and welcome to Babypips.
You are not alone and this is a very natural feeling. You are not stupid - you are trying to learn something that is very attractive and potentially very rewarding. I persist at trading, after nearly 15 years, because like you, I thought I was stupid back in 2010 when I paid $3,000 to attend a one week trading course, and could not instantly make money. Only last year did I finally become profitable over all that time, and it happened because of cryptocurrency, not traditional Forex. But I applied all the tools I had learned trading Forex and some indices for a long time. Unlike many others, this has never been a passion for a ācareerā, it is just one of many things I have done in life that all have a common theme of providing diverse sources of income.
Oanda used to do copy trading - they may still do. I had thought about it but never did it. As others have said, persist, starting with any simple strategy, and use a demo account so you can build your self confidence if for no other reason than to put on a few hundred trades so the mechanics is just like driving car, or shopping for groceries. You donāt really think too deeply because you have done it hundreds of times. And if it is demo trading, it has no direct cost. Only your time to place trades - all types of trades, just for fun. One time I traded exactly the opposite of what my trading plan told me to do, and I was no worse off than if I had traded according to the plan. That told me that my plans had no edge. I was losing whether I traded to plan, or to the opposite of plan. That baseline taught me to be patient, and years later, I very rarely make a rookie error placing a trade the wrong way around or for 10 times my intended stake. Stick at it, and make sure you enjoy the journey.
