Gordon,
Replace any of those "Trading is" statements, with "Life is".
They're an artistic way of describing what is for some, the biggest hurdle in trading. Human psychology and perception.
Whether a trader designs systems or manually trades, the trader must learn to follow rules, prepare for change, and adapt.
Such is life wouldn't you say?
As in life, if you want to accomplish anything you have to learn as much as you can, and then attempt to execute.
Examples:
Asking that girl out
Holding on to her
Wanting to become an astronaut
Starting a hobby
Sometimes we succeed, sometimes we fall flat on our face.
There's nothing wrong with crashing and burning either! It's all part of life. The higher the goal set, usually the fewer people will be able to accomplish that lofty goal. I know most humans could do probably anything they set their mind to, but the work required gets in the way of their happiness.
Trading is definitely one of those loftier goals. I'm succeeding now, but I realize that nothing in life is guaranteed. If I eventually fail, I will do something else. The key is happiness in the end.
So, decide how much you want to put into the learning side, and go for it!
I think you understand the mechanics of trading well enough, but the psychology side can only be learned by jumping into the game.
My advice to you would be:
1) Get one or two sets of rules
2) Backtest them on 20-30 stocks and see how they did in different timeframes
3) Find the most productive stocks in the group and look at the losers/drawdowns, and see if you can find any indication as to why they happened. (understanding news, and the macro economic picture is very important in trading, usually)
If you find something that looks like it could work, go for it!
4) Trade small until you feel comfortable!! This is key! Testing the foibles of your system and your mind with small sizes will help you develop your rules and train your mind with a safety net. Don't let greed make you up the share size, let the comfort of successful trades/rules do that for you.
(I watched my system forward test for 2 months before I even let it trade! Even then I manually executed it at first with small size to get the feel for it)
If in the end, if it doesn't go right, you have to weigh your own happiness vs. the time/energy/cost of trying again. All those derogatory "quitters never win" statements that float around are BS. The smart guy will realize that he's wasting too much time/money going for something HUGE, when something a little smaller could be much easier to attain.
(Life is full of cool things to do!)
Good luck Gordon,
