The book I recommended, the Disciplined Trader, by Mark Douglas really helps you understand how to deal with the anxiety that leads to stupid trades.
It is a book someone in IRC recommended to me after I told him I had sold off shares of ActM and regretted it.
Is it this thread where someone was recommending a trading book to buy from Amazon? Can you post again?
+1 LorenzoMoney for sharing a great piece of information to the bitcoin community.
That book is a must read for every trader.
I read that book long time back, It has helped me a lot in my trades.
