Start learning to plot some technical indicators

I'm new for stock markets and has been trying to analyze some stocks from my ideas, but I am not sure if mine is correct.

I'm starting learning how to find prices to open an order and prices to sell out for both taking profit and cutting loss. I find RSI, MACD, Fibonacci, and EMA very effective for this purpose.

Right now, I am about to open an order of SIRI at 0.87Baht. Cut loss at 0.84 and take a profit at 0.96-0.97Baht

Any expert or guru who finds my techincal analysis incorrect can get it correct and explain it to me.
