Why these three, and in this order
Almost every method that fails in retail hands fails the same way: it reads the chart once. One tool produces one level, the level is traded, and when it does not hold there is nothing left but conviction. The alternative is to ask the same question of sources that do not share a data set — and these three guides cover the two of those sources that are hardest to learn from scratch.
Read in order if you are starting out. Volume profile gives you the map of where business has been done. Order flow tells you whether the level in front of you is being defended right now — both of these are the volume read, seen at different resolutions. Options positioning is the genuinely separate one: a different market, different participants and a much longer horizon, which is precisely why it is worth the effort.
The read these guides do not cover is structure — where the levels come from in the first place. That is the subject of the course itself, and of the free Block A preview lesson linked at the foot of this page.
Each guide has a section on what its tool cannot do, and those sections are the most useful part. Every one of these tools is sold somewhere as a complete system; none of them is one.
If you would rather start with numbers
The free calculators answer the arithmetic questions — position size, expectancy, risk of ruin, portfolio heat. The Trading Lab settles the arguments with simulation, and Mythbusters takes the industry's favourite beliefs apart with arithmetic. The glossary defines every term used across all of it in plain language.
