I too can say that using multiple indicators can get someone confused, I am not that sure about that but many traders have told me that before. Like me, I use only two or three indicators which is enough for me. I use Bollinga band to know when a market is over bought or oversold and this is very helpful, I joined it with relative Strength Index which also having similar function with Bollinga band but gives me in persentage the level of over bought or oversold market. I was not using indicators before, I have just started it and it is working than I thought. Maybe if I go further to use others, maybe trading will be better for me, but if I will have to be truthful, I have most positive results when I have been using Bollinga band and Relative Strength Index.

Using multiple indicators can get someone confused on the market direction. Using trend line is not a guarantee because it is a biase indicator since drawing the line is individual based. For example you can draw up your trend line and the next person draws placing it in a different price. However, support and resistance helps alot. Candlestick on a longtime duration can be used as trend indicator.
