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's why it makes it difficult. If you can't take trades, then you are not trading at all. I also noticed that when I was just learning it and reading the sample chart, it was really easy to spot things where to trade or where to stop, but when in the actual market, it is difficult. Indicators are really one of the best things you should rely on (to know when to trade or exit) and also do it in demo because, as you can see, most experienced traders can spot what kind of movement they are looking for, so doing your strategy in demo could gain you experience and make you more confident in taking trades in the real market with real money.
