At the most basic level, 2 things have proven to be most helpful
1. Take a straightedge and draw trendlines on any chart. Let the trendlines guide you.
2. Ask any kid if the chart is going up or down. Follow his/her advice.
If these 2 aren't working for you, study the chart and decide what you think you should do. Then take a small amount of capital and do the opposite. If it works out for you, slowly apply more and more capital till you become comfortable being a contrarian.
Now if you really want to get deeper than that into technical analysis, it can get very murky quickly as you'll have indicators telling you opposite things and you'll have to figure out which ones to listen to at any given time and which ones to ignor.
The answer to that typically depends on determining if you are in a trending market or a sideways rangebound market. In the end, numbers 1 and 2 above might be the simplest answer to that anyway.
Good Luck,
