Guideline 09. Again and again, edge is always small

Guideline 08

Guideline 10

Every time you buy above the high of the prior bar on a stop, someone else is shorting there with a limit order. When you sell one tick below the low of the prior bar, there is a strong bull who is taking the other side of your trade. Always remember that nothing is certain, and the edge is always small because there are smart people who believe the exact opposite of what you do.
