in my opinion indicators can help a lot. I often work with fibonacci retracements for example. They point to specific turning points in markets' movements and then I use the identifed support and resistance levels to plan my next trade. I know some other indicators too, but I mostly use fibos.
more Upper Indicators are MA (Moving Average) Envelopes Bollinger Bands Parabolic SAR Volume by Price Price Channel A/D (Advance/Decline) Line
and tpossibilities for Lower Indicators are for example: Volume RSI (Relative Strength Index) MACD (Moving Average Convergence Divergence) Fast Stochastic Slow Stochastic ROC Williams %R Money Flow Volume Accumulation Volatility Fast Volatility Slow Momentum
