The book “Trader's Trading System: A Factor of Success” is the first to discuss methods for creating trading systems and provides the results of their testing. There are many manuals that describe classical technical analysis, and very few that tell how exactly to apply it to work in specific markets. This publication fills this gap. Now no one has any doubts that successful trading in financial markets is usually based on the use of trading systems (TS). Therefore, here we discuss in detail the basic rules for constructing trading systems based on technical analysis, showing the main issues that arise when creating such TS, and tells how these issues can be resolved. Oscillator signals are also covered in detail, including divergence and stochastic setup.
