That's the right approach, keep things as simple as you can and trade your plan as defined. Most fail because, they don't actually have a tested methodology, their system is too complex or they lack the discipline to trade it.
Yes, I had a very simple system: Buy low sell high and buy high sell higher. But I could not make money day trading: Market refused to follow my system.
Not exactly. You can gamble on probabilities your first day trading. (Insert sarcasm). It has taken me quite a long time to find edges to exploit markets. My only risk is the exchanges requiring more margin for professional customers. I do not gamble, hell I don't even buy lottery tickets. I trade because exploitable edges are available and I didn't go to med school.
Trading is extremely easy Today(8/31/17) I made $200,000 in just 2 minutes of trading. I normally sell my training course for $9999 but I'm having a sale you can get my exclusive video trading course this week only for $199 you will learn top secret methods the big boys don't want you to know. NOTE:: if you can't tell I'm joking don't report me for trying to sell a course.
Instead of learning to trade...you should package up all that trading mumbo jumbo...and sell it on a website and advertise it on Google search engine, Who knows...you might just get lucky, and have an unexpected enterprise on your hands, Take photos of yourself holding lobsters and ass, with your laptop in the background having rainbows of cash exploding out, If that sillyness works for some people...who's to say it won't work for you as well, (if you are fruitful, i want a 20% fee of your net)
Everyone knows if someone is selling something regarding trading, the only one getting rich is the salesman. Gathering capital is a whole different story.
