Stock trading - Restart

In the last two years I use a lot of technical analysis tools to find the best point to buy and the best point to sell but I failed. The problem is I was lost between lines of these indicators, confuse , not confident to buy or sell. I lost around 30% of my money for all of my mistakes. This year,2017, I will try to limit technical analysis indicator to four indicators, Price trend line, Volume, MACD and RSI. Hope it will go well.
