Order-flow and depth studies
Tape reading, absorption, large-order detection, book imbalance. Written against the live order book rather than reconstructed from bars.
Sierra Chart · ACSIL · custom development
Custom Sierra Chart studies, written in C++ against the ACSIL interface — order flow, market depth, options positioning, session structure. I am not a contractor who read the documentation. I run this code on my own charts, on my own money, every session, and I publish the research that says when it does not work.
The work
All of it ships as a compiled study that installs into Sierra Chart the way any other study does. No web app to log into, no broker integration, no second subscription.
01
Tape reading, absorption, large-order detection, book imbalance. Written against the live order book rather than reconstructed from bars.
02
Dealer gamma, zero-gamma crossovers, strike walls, expiry structure — computed off-chart and drawn as levels, so the customer's machine does no heavy work and holds no data licence.
03
Opening range, overnight frame, value and profile levels, deviation projections, volatility-scaled ladders. The unglamorous studies that a desk actually looks at.
04
If you sell studies, the licence is the product. Per-account entitlement through Sierra's own gate, tiered so one build can serve several price points, and revocable when a subscription lapses.
05
Chartbook parsing and patching, tick and depth file readers, scheduled pipelines that write what a study draws. Most of the hard problems live here, not in the study.
06
An inherited study nobody can compile, a drawing that leaks across chartbooks, a number that is quietly wrong. Often the most valuable thing on the list.
The evidence
These are the artifacts behind the claim. Sierra's bundled example sources are excluded from every figure below — this is work I wrote.
How I work
01
New behaviour ships as a new version with a new export name. A study that draws on your chart today will still draw tomorrow, because I did not touch it. Contracts are additive; that is the whole discipline.
02
Stale feed, missing key, a file that did not arrive — every failure resolves to a visible dead state with a reason. A panel that prints a confident figure because a parser broke is worse than a blank one, because you will act on it.
03
Including the ones nobody tests: hiding the study, removing it, switching chartbooks, closing the platform. Leaked drawings are the most common defect I am handed, and they are entirely preventable.
04
Pre-registered, run against a null that shares the same structure, and killed if it fails. Forty-nine of my own ideas have died that way, and the kills get published next to the keepers. You are hiring the person who throws his own work away.

Describe the instrument, the data you have, and what the chart should show you at the moment you need to decide. If Sierra already does it natively I will say so and you will have saved a conversation. If it is worth building I will tell you what it takes.
