Price moves in swing cycles that contract and expand as they go through their process. By understanding this process, we understand the principles of price flow and can then make trade decisions anywhere along the way.
Real trading has to do with simple observation and seizing opportunities, however they might present. I use the CAD to illustrate this by looking at the structure and process of a valley structure and its components, like gaps and coils, which express the principle of contraction and expansion. I then take you through possible trade opportunities along this process. This is what I do when I trade.
