Forgot her name but love her post many years ago! Wonder how she is doing today!
Here's my beliefs on trading after a couple decades of being involved with futures and options.
1. 99.9% of trading is between your own ears. If your not successful it's your own psychology that's keeping you out of the winners circle. A better technical method will not help you.
2. You can define your own edge by simply sticking to any simple method and learning every nuance of it over time. Getting the mindset to trade it is where you need to put your energy.
3. Entries are more important than exits, period. If you get a good entry you will risk very little and it's more likely you'll get a profitable exit.
4. Diversifying in the futures market is, over the long run, a waste of time. Learn a couple markets like the back of your hand and trade the hell out of them. I prefer to trade one market at a time, all in.
5. Not all types of trading will allow for the use of stops. There are times they can be used and times they will not do your bottom line any good. Know the difference.
6. 'Cut your losers short' & 'execute your edge without hesitation' are about the only trading cliche-type adages I agree with, the rest aren't worth the paper they're written on i.e. 'let your profits run'. Letting your profits run is a good thing, but not all methods require a a 'run' to be successful. In other words, don't always swing for the fences, or, even better, know when to swing for the fences.
Trading is tedious work but it really isn't all that hard to do if you can master the psychology of it. A system can work but few will execute it properly, especially your broker. You do not need to be a genius to trade as it is a very simple format >>> define your risk (and accept it), execute your trade, know where you want to get out (or, at the very least, where you want to start trailing a stop). The two best books ever written on trading are by Mark Douglas and I suggest reading them. The Disciplined Trader is a better read if you have had some college level psych and Trading In The Zone is a great read if you've been in the markets for awhile. Either book will disappoint you if your looking for a new fail-proof method to trade with.
