Oh, I'm done.
A lot of you want to know what or how I traded, but I have really no secrets to teach because I've tried so many things and they have all worked for me for certain periods, but the problem is that they didn't maintain long-term consistency.
Strategies don't last forever. Just when you think you've figured some profitable plan, you might make good money for awhile, but before you know, you're forced to the drawing board again to chase a new system because old methods have stopped working.
There were optimal strategies in 2001, 2002, 2003, etc., but they were only good for certain periods. Change in market behavior is pretty much guaranteed. I think any long-term trader would agree that very few strategies remain robust over a long period unless you have inside information or lots of access to arbitrage.
Things like discipline, money management, etc. are very basic but not special skills. They're essential concepts and everyone should have them down like ABC's, but they are not keys to making money.
Because at the end, you still need profitable strategies to make money.
With so many constant changes, an obvious solution for a trader is to find ways to adapt to new market shifts. Well, that's easier said than done, especially if you expect to do it consistently for a long period. Sometimes there are gradual shifts in trends; sometimes there are drastic shifts. Characteristics are observable.
Former super traders wouldn't be selling their old methods or writing books on archaic strategies if they were still working or if they knew how to continue making money in the new markets.
And I wouldn't really equate running a restaurant business to trading even though the initial success rates seem comparable because unlike trading, the formula for a successful restaurant is not really going to change that much. By your second or third attempt, you should probably have a fairly good idea on how to run a good restaurant. You might have a better idea on how to have a better marketing plan, better customer service, better food, better settings, location, supply cost reduction, etc. Those acquired strategies are probably going to work in the future and aren't going to change that much in the restaurant business.
But in trading, it's not that simple because strategies that you have acquired from previous tries may sometimes even be strategies you'd want to totally avoid in the future. It's pretty rare that a trader can trade well with the same methods for many years. Most profitable strategies have expirations and will be unreliable some day. The hard part is figuring out when that expiration is.
