The Ultimate Code of Trading:

Only trade within your own trading system's market, and be clear about abandoning markets outside the system!

The Four Steps of a Trading System:

First: Confirm the trend (going long, going short)

Second: Choose the entry position (resistance level, support level, breakout level)

Third: The exit position (take profit and stop loss)

Fourth: Capital management, how large a position to take (the capital ratio of each trade)
