Can a Simple strategy explianed in one sentence really work long term?

[Kai]

I trade pre-off order flow profitable, my strategy is so so simple, I could explain it in one sentence it's that simple

Is this really enough tho for an edge and long term profits

How simple is your strategy?

Philosophy aside, if you can precisely and easily explain your edge then you should be moving in the right direction if you ask me. I have found that edges and concepts are usually very simple, it's the (proper) execution that is the complicated part.
