One of the things that I like doing with charts is to look for short term examples that unfold over the course of the day - for this the 30 minute chart is my favourite because I feel you can eliminate a lot of the short term noise of the market whilst being able to trade within or externally to prevailing market trends.
The W Reversal is a particular favourite pattern of mine for this purpose because it allows to look quickly for reversal signals. Take a look at the chart below:
As you can see from the highlighted area the price has gone through a decline in price and then started to base out. The key of this section firstly is that you have a reasonable amount of trending movement - I know this sounds subjective but if you look at some previous examples on the blog you will see what I mean.
From here you need a trough to form outside of the Bollinger Bands followed by a peak inside the Bollinger Bands (though no penetration of the moving average is acceptable) and then another trough within the bands. As the Bollinger Bands are volatility based lines (2 standard deviations about the moving average) we are looking at this as a reduction in volatility and a precursor to a shift in direction.
Once the second trough is confirmed you can then place your trade with the stop typically placed under the lowest level of the second trough.
You can choose then to trail your stop or set a profit target - typically this would be a multiple of the risk that you are taking such as 1:2 or something like that. You can use an automated trailing facility but be sure not to set it too close or normal price volatility may see you get stopped out unnecessarily.
This is a very basic primer on this strategy but be sure to look through the rest of the blog for examples of this and its bearish cousin the M Reversal.
All the best,
