The Rebuild: Why billcara.com Is Going Fully Independent
April 27. 2026
After more than two decades of publishing at billcara.com, and recently at Ghost and Substack, I decided to rebuild the entire system from the ground up — on my own server, in Germany, on open-source software, with new editorial architecture. This note fully explains what I am doing, why I am doing it now, and what changes you will see as a subscriber.
The short version: I have always been a Free Market Patriot, with a need for independence. To anyone following my journey, you can see why — independence from platforms that can deplatform me, from AI services that can quietly degrade or change terms, from payment processors that have already failed my subscribers once, and from the political weather of any single country. After fifty years in global markets, I have learned that the people who survive long cycles are the ones who own their infrastructure. It was only after venturing into social media that I saw the true value of what I had before at billcara.com. With the changes I started this month to revert to what I had, I should have done this sooner.
What is changing
Three things are changing at once, and they are connected.
First, the system moves to my own server in Germany. Recently, pieces of the operation have lived on third-party platforms — Substack before Ghost Pro, various analytics tools, a mix of cloud services. Each of those platforms is a tenancy, not an ownership. When Substack’s payment processing failed my subscribers and impersonation scams went unaddressed, that was a tenancy problem. When AI providers change their terms or quality without notice, that is a tenancy problem. The rebuild puts the database, the content, the subscriber relationships, and the analytical pipeline onto hardware I control, in a jurisdiction with serious data-protection law and political stability that does not depend on the outcome of any single election.
Second, the software stack becomes open-source where it matters. PostgreSQL for the database. Open-source AI models, including DeepSeek, alongside Claude where Claude is genuinely better. Open-source tooling for the data ingestion that feeds INSTAT and Perspective. The reason is not ideological, and it is clearly not about cost, though the operational savings are real. The reason is that open-source software cannot be unilaterally taken away from me, cannot have its pricing changed overnight by a vendor’s quarterly board meeting, and cannot quietly start producing different results because someone upstream decided to “improve” it. My technical associate has two decades of experience building exactly this kind of stack, much of it forged in Cuba, an environment where commercial alternatives were never available. What looks like a constraint to others is, for us, a competence.
Third, the editorial architecture gets a missing piece. In addition to the public Navigator, which is being redesigned from the bottom up, I will soon introduce a fourth premium report, Perspective, and a single discussion space called Forum. More on both below.
Why now
I have been thinking about this rebuild during the months I struggled with the conversion of billcara.com to Substack and Ghost, but the decision crystallized over the past month for three reasons.
The first is that I have spent a year using AI heavily in the workflow, and I now understand the difference between AI as a probabilistic tool for creating and a deterministic tool for records management — which is software. I understand the difference between AI as a tool I control and AI as a service I rent. The rented version is convenient until it isn’t. Quality drifts. Terms change. A model I have built a workflow around gets retired. For a publication that subscribers depend on for their financial decisions, that is unacceptable vulnerability.
The second is the political environment. I am eighty-three years old and I have watched a great many cycles, but the current one has features I have not seen before — the willingness of governments and large platforms to treat publishing infrastructure as a lever, the speed at which payment rails can be turned on and off, the deplatforming of people whose only offence is being inconvenient. I am not predicting any specific outcome. I am saying that a serious publisher in 2026 should not be in a position where any one company or any one country’s regulators can end the operation with a phone call. Germany and Canada are no guarantee against political chaos — nowhere is — but a server in Germany I own, on hardware I control from Canada, in jurisdictions with strong data-protection traditions, is several layers of insulation that the current setup does not have.
The third is that the existing report structure has a gap I can no longer ignore. Premium subscribers have been getting INSTAT (the data), Playbook (the strategy), and Portfolio (the trades, when I was up to it), but they have not been getting the step in the middle — the part where I work out which of the price movements I am seeing is actually changing my thinking, and why. That step has been happening in my head and leaking into the other reports in ways that blurred their purpose. Perspective fixes that.
Perspective: the missing report
Perspective will publish daily, immediately after INSTAT. It is short — one to two pages maximum — and it does one thing: it identifies the three to five price dynamics currently reshaping my investment hypotheses and tells you what I am still uncertain about.
What Perspective is not is more important than what it is. It contains no data tables (those belong to INSTAT). It contains no general principles or rules (those belong to Playbook). It contains no trade announcements (those belong to Portfolio). It contains no recommendations and no calls to action. Perspective is diagnostic, not prescriptive. It is my thinking in progress, not my final conclusions. The phrasing you should expect is “this is shifting my thinking toward...”, “I am not sure yet, but...”, “what I am watching next...” — the register of a critical thinker working through a problem in real time, not someone delivering verdicts.
The four reports together form a continuum: information (INSTAT) → interpretation (Perspective) → strategy (Playbook) → action (Portfolio). Each one answers a different question, and none is allowed to do another’s job. The rebuild is the right moment to enforce that discipline at the system level rather than leaving it to editorial willpower.
Forum: where members talk
Alongside Perspective, the rebuild introduces The Forum — a single discussion space that replaces what used to be called the Cara Community. The name change is deliberate. The discussion space does not belong to me; it belongs to the members who use it. Putting my name on it was a habit from earlier years when the readership was smaller and the relationship more direct. With subscribers in many countries around the world, the space needs a name that signals what it is rather than whose it is.
Forum is the only place on the site where members can comment. It is for opinions that are not necessarily tied to current price action — not a day trader’s room. The commentary and discourse shall be about questioning a report, floating an idea, taking issue with something I have written, raising a topic the reports have not covered. It is where members argue with reasoning, in the older sense of the word forum: a place for serious public discussion among peers, and a place for students of the market to observe others.
To start, Forum will be open only to paid and gifted subscribers. I may extend access to registered free members later, but I am not planning to. The reason is straightforward: a discussion space is only as good as its participants, and the members who pay for the reports have already shown they are serious about the subject matter. That is the discussion I want to host.
What stays the same
Navigator will always be free. INSTAT keeps its scoring methodology — the AT, ST, IN components and the −100 to +100 composite — unchanged. The Four-Gate Funnel inside Playbook (Ziggma quality screening, INSTAT floor exhaustion, RSI/MACD signals, Point & Figure reversal) is unchanged. Perspective will be linked to INSTAT. Pricing across the four reports is unchanged for now; pricing decisions will come after Perspective has run for a full quarter or more and I can see how the four reports work together in practice.
The Maverick program — a free educational initiative for young people exploring the market and possibly finance careers, built around paper trading and Value Line research on the Dow 30 — also continues unchanged.
What this means for you
If you are a current subscriber, you do not need to do anything. Your access carries over. You will start receiving Perspective on the same cadence as INSTAT, and your Forum access will be activated when the rebuild goes live. Subscription tiers will let you include or exclude reports as you wish.
If you are not yet a premium subscriber, here is what the rebuild will offer: Navigator remains free and open to all readers. The four-report structure — INSTAT, Perspective, Playbook, Portfolio — and the member Forum sit behind the paywall, and together they will be the full premium offering once the rebuild is complete.
A closing thought
I have been published at billcara.com for over 22 years — since April 2004. The readership developed into something I did not fully anticipate when I started, in days when I was still learning how to do links and screenshots. The responsibility that comes with publishing deep financial analysis and guidance to a global readership is something I take seriously enough to spend my eighty-third year rebuilding the entire operation rather than letting it ride on infrastructure I do not control. In June, my US Series 65 fiduciary license will have ended because it is no longer needed. My reports will always carry the fiduciary label, because that is what defines me.
To sum up, independence is not to me a slogan. It is a list of decisions: where the server lives, who owns the database, which software can be taken away from you, who can shut off your payments, who can change the terms of your AI tools, whose name is on the discussion space. I am working through that list. I could not do it without Alexei, my longtime technical associate. The rebuild is the result.
Perspective starts soon. Forum opens with it. Everything else continues.

A note on the rebuild: the new system is being built on PostgreSQL and open-source tooling, with AI analysis running on a mix of open-source models from China’s DeepSeek and narratives from America’s Claude. The hardware is in Germany. The full editorial and technical specification for Perspective has been written and will guide the build from Canada. The technical team is in Brazil. Questions from subscribers are welcome through the usual channel, and, soon, through Forum.
