To show how effective this approach, the best thing I think is almost one example of so-called book. Look at Figures 1 & 2 (in English, if you have any questions regarding the language during the meeting). Figure 1 shows the recent price action in a period of 60 minutes. Figure 2 shows that a detailed action 5 minutes. Looking at the chart of 60 minutes, a clearly identified with the bearish price channel testing the high-band channel (in fact it is testing the resistance of the channel), in what could be a very good entry SALE. However, we still do not know whether the channel will hold the test or change in the price break. It's time (now, not before) to put their eyes on the graph to 5 minutes, to find answers to that question. In addition, we like what we see: the MACD to confirm a bearish divergence, just when the price is testing the high-band channel. At the time that this divergence is confirmed, we look at what the price. We see is below (again) the resistance of the channel. Time to sell. Thus, we succeeded in maximizing our expectation for this operation, and could hardly have got a better entry price.
What about output? Continue reading the chart. As the operation progresses, we see that the 1.2015 support is broken, but also that the MACD beginning to form a bullish divergence (Can you find?). Well, there would be. Once the divergence is confirmed in 5 minutes, the operation closes. Obviously, this is a very basic, but what they want to say, if you will be rewarded kept simple. Therefore, it is plausible that a simple strategy like this can be effective most of the time.
Sometimes, the exit strategy based on short-term chart, you may cause a winner to close early. Those to which these forms of trading do not like what as reason. The only thing this can be said is that with this simple way out you will be completing transactions to complete (maximum possible range) by 80% of the time, and this simply means that it's worth it.
