Trading is not so difficult as it was told. But the difficult part in trading is when to enter the market and when to Close the market. So when do you think one can buy or sell (enter) the market? Using the candle sticks to predict.
That is why you need to create a plan (entry and exit plan), however, this will work only if you are too serious about it.
Candlestick, price chart, MACD, etc...we can use some trading tools applicable as a basis of our analysis, TA, and FA. As having these things, it was easier for us to speculate on the market, however, this never means that we can predict what really happen but at least we can anticipate any possible change that may occur.
