The column

This site does not publish strategies, and it is not going to start. What follows is an argument for why that is the correct decision rather than a limitation.

A strategy is a claim about the future made under specific conditions. It has an instrument, a timeframe, a session, a fee structure, a fill assumption, a position size, and a person with a particular tolerance for being wrong attached to it. Strip those away and what remains is not a portable rule. It is a sentence that sounds like one.

This is why the strategy sections of most educational sites age so badly. The rule was never the thing. The conditions were the thing, and the conditions were never written down.

What the rest of this site is for

Every concept documented here is a measurement. Cumulative delta measures net aggression. A volume profile measures where activity concentrated. Implied volatility measures what the market is charging for uncertainty. None of them is an instruction, and the pages are written to make the difference obvious: what the tool counts, how it is calculated, and specifically where it misleads.

That last section is the one worth reading twice. A measurement you understand the failure modes of is a tool. The same measurement without them is a superstition with a chart attached.

What to do instead

Combine. No single measurement carries enough information to stand alone, and the ones documented here were designed to be read against each other rather than in isolation. Delta means something different at the value area high than it does in the middle of a balanced session.

Then test the combination, honestly, on data you collected yourself. Not by scrolling back through a chart and noticing the times it worked, which is the most reliable way ever invented to convince yourself of something false. By defining the observation precisely enough that you could hand the definition to someone else, recording every instance it occurred rather than the memorable ones, and counting.

Most of what you test will not survive that process. This is the process working, not failing. Every honest researcher discards far more than they keep, and the discipline of discarding is what separates a method from a collection of anecdotes.

Data never lies. The story you wrap around it does.

The uncomfortable part

Sample size is not negotiable and it is larger than you want it to be. Markets produce enough noise that a handful of confirming instances is indistinguishable from chance, and the human mind is exceptionally good at finding structure in noise. Nothing on this site can protect you from that. Only counting can.

So the honest ending to every page here is the same: now go and see whether it is true where you trade, on your instrument, in your session, with your costs. That is not a cop-out. It is the only version of the answer that is actually yours.
