Diary of a Professional Commodity Trader Trading is generally far more difficult in practice than in theory. The reality is that no trade set up or individual trader or system can identify profitable trades in advance with complete certainty. In A Year of Trading, long-time trader Peter Brandt reveals the anxieties and uncertainties of trading in a diary of his 2009 trades. He explains his thought process as he searches for trading opportunities and executes them. Each trade includes charts, an analysis of the trade, and a play-by-play account of how the trade unfolds.
