Totally agreed! 
Human nature causes most people to seek high percentage win rate (e.g. 70%) to prove they are right most of the time. This results in very competitive environment and market dynamics for the high percentage edge. i.e. even you find one, the chance is it will disappear soon enough, especially HFT and machine learning robots are scouting the market 7x24.
IMO, going longer term and shoot for higher profit/loss ratio would be more robust. If you can get win rate 40-50% and profit/loss ratio 2:1, you will do very well.

its like in the days of the gold rush. The guys selling you their burgers (books), their shovels (software) and their crooked laws (Goldman Sachs) make the money. The guys actually digging for the gold mostly make very little, loose it all or get screwed by the powerfull behind the scenes (special treatment for the big banks).

Hi Howard

 

I would say that the trading community probably does recognise the importance of stationarity. I'm just speculating though. Let me explain.

 

The data science community tends to include members, most of which have mathematical and/or science backgrounds. So they learn about the theory, practice, and important here, nomenclature. Whereas the trading community tends to include a large number of members without any such background, and hence they tend to be less sophisticated*. They tend to teach themselves as they go along. So they dont always use the accepted scientific language or notation. However, I often see statements similar to 'systems will be profitable when they are in sync', which in my mind is basically a laymans way of stating stationarity.

 

Anyway, this is just anecdotal opinion, and of course ymmv. I havent actually surveyed the entirety of the trading community...

 

*Also, please note, I'm not suggesting less sophisticated means dumb, or any other such aspersions.
