If you don't have experience running a business, the smartest thing is just buy shares of a company say nestle, public banks and let the management have the headache of running the business.

You don't need tech or pattern. That's for trader. Trader don't bother about fundamentals of company and they hol short term say few minutes to a week.
View stocks as business and not numbers bouncing up and down on your screen. If the business is good overtime the price will move up on it's own.

Your friend have been scam. Nowadays lots of people offering course say they have inside infor, special signal that will help you beat the market. All BS one. If their signal so good, why give to people? Cause they are not making much from signal but from selling the course. One course RM2k-4k. 10 people already RM20-40k.

You can learn everything you need online via blogs or youtube.

There are other ways to make money than being a trader. It is become an investor or you can go the dividend route. Buy companies and get paid to hold those companies. Over time as mentioned, good business the price will go up. Dividend received will also go up.

FYI, I spend nothing on stocks other than commission and I am generating at least RM20-30k/year off my investment. And no I never need to sell my stocks. The RM20-30k/year is from my dividends or my options premium). I am still holding on to my stocks I bought like 5-7 years back.
