Hi...
I personally would consider two categories of reversal indicators: Technical Analysis ( Price Oscilators ) indicators Support/Resistance areas which can be determined in a variety of ways depending on your personal goals trading style. The Technical indicators I like to use to demonstrate divergence price action are the traditional: Williams %R Slow Stochastic RSI. These definitely help determine the end of a trend ( even micro-trends on a 5 or 30 min. chart) or an area where the market will reverse. However for me a more important method of attempting to spot reversal comes determinimg "stone wall" areas of support resistance using a Fibonacci retracement grid superimposed onto a clestick chart. Lots of members here like to use a variety of methods of this type. There are other effective ways of determining these pivot points for me there is so much info in Moneytec on these different approaches I am hardly qualified to vouch for or discuss them. But in terms of tech. analysis good reversal/divergence indicators the I mentioned are very very helpful. Larry Williams creator of the Willimas %R has an excellent website that helps explan this study far better than I ever could:
