The structure of the trading system should be based on the market behavior, but rather on the movement of the trend. To do this, first you need to understand inner organization and life cycle of trend. Taking into account the previously described behavior of speculators and hence the price movement, we can assume that at any moment the markets consist of three trends. The first trend is the longest, consisting of several months, you need to use to determine the direction of the market, and in the direction which you want to open positions. The second observable movement of the market can be a correction of the trend, which will consist of a few days, and determined by, the use of more sensitive indicators. Recent market moves a little bit like a sideways trend between correction and main trend extension is the short-term price movement in one or two days that is used for precise entry. For accurate output should be used also is a short-term movement, but in this case the main trend will not be followed by correction, and a new trend in the opposite direction. Following this understanding of the market, to open positions you need to use two or more trend indicator, which signalizes about the opening position, and an oscillator or trend indicator to close a position. A more detailed description of the use of these indicators are reported below.
