Fundamental or Technical Analysis? - Revisit 3

Read? Fundamental or Technical Analysis? - Revisit 2

Again and again. People will ask me for advice which technical indicators are good to use?

But I don't really use any "good" technical indicators for Entry and Exit signal. I really don't know which are the good ones.

I know most technical indicators are developed by Gurus who claimed that they are reliable and profitable if used "correctly". But, then how outcome so many new indicators were developed when the old indicators are reliable and profitable?

But I still need to know when to buy and when to sell so I use simple support and resistance to determine when to buy and when to sell.

Support and resistance are not known to be reliable. There will always be another new support or resistance once they are broken.

I know I always make mistakes in determining the level of support or resistance but just that I want to make a better simple mistake and that's all.
