Same here. During my over 10 year trading career I've found only 1 pattern which works year after year (gives a positive expectancy). I have used thousands and thousands endless hours to find an another but no luck.
Fortunately 1 is enough.
Mental control and money management of course are mandatory but without an edge (in the long run) mr. Bell Curve will make sure you're not going to make it.
I did a traditional journey with all the bells and whistles until after about 4-5 years understood to clean my charts but price bars and started to see the market which helped me to find this pattern together with a lot of data mining and backtesting.
Yes. I think you just described another criteria of consistency. People would say, this trader reach the stage of making profits consistently, or in another case, this system produces wining trades consistently, or like you said above the pattern you discovered worked consistently. As a scientist, what we value greatly is the reproducibility(repeat over and over again, but not randomly), and I believe engineering works in the same principle. Just for example, if the automobile is functional consistently, then when you hit the gas pedal you expect the car to move, and when you hit the brake, it should decelerate. Of course trading is more complicated than that, but in principle it is that simple, if you appreciate Einstein's simplicity theme.
