The three pillars of a sound swing strategy

Why three, and why these three

It is tempting to think a good strategy is mostly about finding the right indicator or the right chart pattern. It is not. A swing strategy that survives contact with a real market is held up by three load-bearing parts, and they are not a menu you pick from — they are a structure where removing any one collapses the other two. A defined edge gives the strategy a reason to act, but an edge with no risk cap will eventually meet a losing streak large enough to end the account before the edge can prove itself. Sizing keeps the strategy alive, but sizing against an undefined exit is sizing against a loss you have not bounded, because you cannot cap what you have not measured. And a rule-based exit only protects you if the edge was defined precisely enough that the exit levels mean something in the first place.

So the three are really one thing seen from three sides: a strategy that is specific enough to test, sized so a normal losing run cannot kill it, and exited on rules written before the trade opened. The table below is the fast version — what each pillar does, and what its fragile imitation does instead. Each row links to a full lesson, and each lesson shows how a systematic, graded model satisfies the pillar without you having to take anything on faith.
