TA works but is not science, is an art form.
There are numerous technical approaches, the more we use the less chances we have, simplicity is best in my view, drawing the proper trendlines can help as the previous daily highs/lows for intraday, here a tiny reaction is required but not always. One has to find "his way".
Best is to enter at extremes were seems no possible a turn, if you enter in the middle of the chart you will be chopped out, patience is a must, wait for prices to get to you if they react take a chance.
today bought GU @ 4054 where every body was selling and covered @ 4119.
Smaller time frame like 5m will help you enter at better price but they are more difficult to master, 15 t0 60 minutes give more reliable set ups, still patience is a must, you do not have to trade every day...
Here you have it a complete system......
