So far, here's what I've manage to come up with:
1) Edge is a pattern. It could simply be a price pattern on the chart, or it could be a behavior pattern (eg. the interaction between me and/or the market).
2) Edge must be repeatable. It can be repeated, replicated, duplicated each and every day.
3) Edge has a high probability of success.
4) Good entry is a must. Good exit is a must.
5) Good entry is useless, however, if your timing is off.
6) There is no good exit. There is only a proper exit (eg. let your winner run, cut your losses).
7) Good entry is critical, but good exit is even more crucial.
8) Good entry is one with good risk:reward ratio.
9) Getting in too early or too late is a high risk trade.
10) Getting out too early or too late is a low reward trade.
11) Human actions are governed by law (eg. natural law, judicial law, etc.).
12) Laws are devised to preserve self-interests.
13) Hence, human actions are governed by self-interests.
14) Markets are designed to exploit emotions (eg. greed and fear).
15) Prices are pegged to greed and fear.
Pareto Principle (80/20 Rule):
16.1) The market trends only 20% of the time.
16.2) Only 20% of the market participants will consistently make significant amount of money over time.
16.3) What you thought was a winner will turn out to be a loser 80% of the time.
16.4) 80% of the losses can be offset by 20% of the gains.
16.5) 80% of the profit comes from 20% of knowledge and effort. The other 80% is luck.
16.6) 80% of the worst trading decisions almost always stem from lack of discipline, which can be attributed to innate flaws and errors (eg. personality flaws, judgmental errors, etc).
