像孩子一样交易 (Trading like a child)

An Idea

Let's say we're all starting from scratch in developing a daily chart system for Cable right now and we don't have any experience in trading proper price action, don't know (or want to know) how to use indicators, etc. How would a child do it? Who knows, but I'll assume they would think about it more visually - observing what happens in the pattern of bars when big trends have occurred and what happens when failures occur from observation of a picture on the screen. Maybe by looking at enough chart setups we could identify some things that seem to lead to high probability successful trades and take advantage of this.

The concept is based on an assumption (to be proved or discredited) that no matter how random or specific a market might be, impossible to predict or possible to trade with "proper" techniques, do we really require all of this to be successful? What if we could invent some sort of set of rules that when followed, lead to success overall? It could be as seemingly meaningless as only trading on Tuesdays and only ever taking Long trades on the break of Monday's high, it doesn't matter as long as in the long run the account balance is positive and growing.
