Who this is for
- Traders who want their numbers checked without leaving the chart
- Traders running multiple strategies who want a real sizing answer
- Traders who want to know if a drawdown is normal or a warning sign
Built for traders who are tired of guessing.
Cephic is three focused tools — Calculate, Allocate, and Watchdog — built to solve real, repeated problems for people who trade their own money. No signals, no strategies to sell, no team pretending otherwise.
ONE PERSON, BUILT IN THE OPEN · NO SIGNALS OR STRATEGIES SOLD · FREE CALCULATORS, FOREVER
This started as a personal problem, not a business plan. Every trade meant tab-switching to some clunky calculator, every new strategy meant guessing how much risk it deserved, and every losing streak meant wondering — quietly, without a good way to check — whether it was normal or the start of something worse. Those weren't three separate annoyances. They were the same problem showing up three times: trading without solid numbers behind the decision. So the fix became three small, honest tools instead of one bloated platform trying to do everything badly.
Built solo. No team, no funding, no roadmap meetings — just someone who traded, got frustrated, and built the thing that was missing.Three tools. One shared problem.
Each one replaces a specific guess with a specific number — they don't do anything else.
01
Calculate
Free position-size, margin, and risk calculators that live right where you're already trading — so a fast setup never means tab-switching to figure out a lot size.
02
Allocate
Splitting risk evenly or "by feel" across strategies is how drawdowns stack in ways you don't expect. Allocate replaces the guess with a real, correlation-aware weight split.
03
Watchdog
Not knowing if a losing streak is normal is worse than the losing streak itself. Watchdog checks your live account against your own limits and your own backtest, live.
Who this isn't for
- Anyone looking for trade signals or entries — Cephic never tells you what to trade
- Anyone looking for guaranteed returns — every output is a calculation, not a prediction
- Anyone looking for a full trade journal — that's a different tool
Since there's no track record to point to yet
Verifiable, not marketing.
No fake reviews, no bought testimonials, no "as seen in" logos that don't mean anything. Instead, here's what you can check yourself, right now, for free — starting with the calculators:
- Every formula shown in plain language, on its own page — not hidden behind a black-box result.
- Free calculators run entirely in your browser. Nothing you type is ever sent anywhere.
- Fixed, deterministic seeds — the same inputs always produce the same result, today or a year from now.
- Too little data to mean anything? The tool says so, instead of faking confidence with a precise-looking number.
Behind Cephic
One person, building in the open.
Cephic isn't a company with a support team and a sales deck — it's built and maintained by one trader who needed these tools to exist. That means slower feature releases than a funded startup, but it also means every decision is made by someone who actually uses the product, not a committee optimizing for engagement metrics. It's also independent: no broker, signal seller, or educator behind it. Free tools stay free; paid tiers only cover the real cost of live account connections and AI-assisted analysis.
