There are a lot of technical indicators available. But you need to find out which are suitable for you. It's not good to use only a few technical indicators for trade. You need to use various technical indicators to find out a good trade setup.
Personally, I am using:


Fibonacci retracement (one of my favorite indicators for S/R)
Relative Strength Index (RSI)
Exponential moving average (EMA)
Moving Average Convergence/Divergence (MACD)
Stochastic Oscillator.
Moving average (MA)
On-Balance-Volume (OBV)
Volume
Stochastic oscillator

I also using Some customize indicators that I found from Twitter, Some traders post their own indicators that are also good to use.
