+# cTrader cBot scaffold — project rules
+
+A Linux-native toolchain for building cTrader cBots in C# and compiling them to
+`.algo`, plus running/backtesting them headless via Spotware's official cTrader CLI
+Docker image. No Windows, no cTrader desktop app. See `README.md` and
+`docs/research-findings.md`.
+
+## Domain facts (load-bearing, verified)
+
+- cBots are .NET 6 class libraries referencing the **official** NuGet package
+  `cTrader.Automate` (owner **spotware**). Do **not** use the third-party `cAlgo.API`
+  package — it is not the Spotware SDK.
+- `dotnet build` emits the `.algo`; the cTrader desktop app is not needed to compile.
+- `.algo` is a proprietary, encrypted container (file magic = ASCII `algo`), not a ZIP.
+- `cTrader.Automate` 1.0.17 names the `.algo` after the project's **parent folder**
+  (no override property); `scripts/build.sh` renames artifacts to `<ProjectName>.algo`.
+- Run/backtest on Linux requires cTrader 5.4+ console image (`ghcr.io/spotware/ctrader-console`).
+
+## Conventions
+
+- Everything committed is **English** (code, comments, docs, commit messages).
+- New cBots go under `src/<BotName>/`, one class-library project each.
+
+## Skills plugin: project facts
+
+- **Code roots:** `src/` (cBots/indicators), `scripts/` (toolchain).
+- **Build command:** `./scripts/build.sh` (wraps `dotnet build -c Release`, collects
+  `dist/<ProjectName>.algo`). Requires the .NET SDK on PATH or in `~/.dotnet`
+  (`./scripts/install-dotnet.sh`).
+- **Test command:** none yet (no test project). Build success + a valid `.algo`
+  (magic bytes `algo`) is the current acceptance check.
+- **Run/backtest:** `./scripts/run-console.sh` (Docker, official cTrader console).
+- **Issue tracker:** none yet.

+# cTrader cBots on Linux — no Windows required
+
+Build cTrader **cBots** in C#, compile them to `.algo` files, and run/backtest them
+**entirely on Linux** — no Windows, no Wine, no cTrader desktop GUI.
+
+This repo is a working scaffold that proves the full toolchain end to end and gives
+you a starting point. The build was verified on this machine: `dotnet build` against
+the official `cTrader.Automate` NuGet package produces a valid `.algo` on Linux.
+
+## TL;DR — is it really possible?
+
+**Yes**, with two pieces, both officially supported by Spotware:
+
+1. **Compile on Linux** (since cTrader Desktop 4.2, March 2022). A cBot is an
+   ordinary .NET class library that references the official `cTrader.Automate`
+   NuGet package. `dotnet build` runs the package's MSBuild targets, which emit the
+   `.algo`. No Windows, no desktop app. Spotware's own words: *"write code and
+   compile it on Linux or Mac."*
+2. **Run/backtest on Linux** (since cTrader 5.4, ~Aug 2025) via the official
+   **cTrader CLI / Console** Docker image `ghcr.io/spotware/ctrader-console`. It
+   runs `.algo` cBots headless — live and backtest — without the desktop GUI.
+
+The nuance worth knowing: step 2 is *recent*. Before cTrader 5.4 there was no Linux
+runtime, and Spotware staff said so on the forum as late as Nov 2024. Anyone working
+from older information will (incorrectly) tell you it's impossible.
+
+See [`docs/research-findings.md`](docs/research-findings.md) for the sourced details.
+
+## Prerequisites
+
+- The **.NET SDK** (6.0+). Nothing else is needed to compile.
+  Install it locally without root: `./scripts/install-dotnet.sh`
+  (drops it into `~/.dotnet`).
+- **Docker** — only if you want to run/backtest via the official console image.
+
+## Quickstart
+
+```bash
+# 1. Install the .NET SDK locally (skip if you already have `dotnet`)
+./scripts/install-dotnet.sh
+
+# 2. Compile every cBot in src/ into dist/*.algo
+./scripts/build.sh
+
+# 3. Run / backtest headless in the official cTrader console container
+#    (discover the exact flags for your image version first)
+./scripts/run-console.sh --help
+```
+
+After step 2 you get `dist/SampleCBot.algo` — a ready `.algo` you can also import
+into the cTrader desktop/web app directly.
+
+## Repo layout
+
+```
+src/SampleCBot/         A complete example cBot (SMA crossover)
+  SampleCBot.csproj     SDK-style class library referencing cTrader.Automate
+  SmaCrossOverBot.cs    The Robot class
+scripts/
+  install-dotnet.sh     Local, root-free .NET SDK install (~/.dotnet)
+  build.sh              dotnet build -> collects dist/<ProjectName>.algo
+  run-console.sh        Thin wrapper over ghcr.io/spotware/ctrader-console
+dist/                   Built .algo artifacts (gitignored)
+docs/research-findings.md   What the research established, with sources
+```
+
+## How it works
+
+**Build.** A cBot project is a normal `Microsoft.NET.Sdk` class library targeting
+`net6.0` with a single `<PackageReference Include="cTrader.Automate" />`. The package
+ships MSBuild `.targets` that, after a successful compile, bundle the assembly into the
+proprietary, encrypted `.algo` container (file magic: the ASCII bytes `algo`). The
+`.algo` lands in `bin/<config>/<tfm>/`; `build.sh` collects it into `dist/`.
+
+**Run.** `run-console.sh` mounts `dist/` into Spotware's official console container at
+`/mnt/Robots` and forwards your arguments to the cTrader CLI, which hosts the `.algo`
+live or in backtest without the desktop app.
+
+## To add your own cBot
+
+1. `dotnet new classlib --name MyBot --output src/MyBot`
+2. `cd src/MyBot && dotnet add package cTrader.Automate`
+3. Write a `class MyBot : Robot` (`using cAlgo.API;`) — see `SmaCrossOverBot.cs`.
+4. `./scripts/build.sh` → `dist/MyBot.algo`.
+
+## Known quirk (handled)
+
+`cTrader.Automate` 1.0.17 names the raw `.algo` after the project's **parent folder**,
+not the project — so multiple bots would collide on one name. `build.sh` works around
+this by renaming each collected artifact to `<ProjectName>.algo`. (The bot's name shown
+inside cTrader comes from the class metadata, not the file name, so this is cosmetic.)
+
+## Limitations
+
+- The cTrader **desktop app** itself is Windows/macOS only — but you don't need it for
+  this workflow.
+- Must be a **modern .NET 6 algo** (cTrader 4.8+). Legacy .NET Framework cAlgo bots
+  must be recompiled.
+- **Live trading** requires a real broker account + cTrader ID credentials passed to
+  the console.
+- The `.algo` format is proprietary/encrypted by Spotware; this scaffold goes *through*
+  the official package — there is no independent open-source `.algo` packer.

+# Research: building & running cTrader cBots without Windows
+
+This documents what was established before building the scaffold in this repo. The two
+load-bearing claims were each adversarially fact-checked (the verifier was instructed to
+*refute* them); both came back **CONFIRMED**. Where a fact was verified locally on this
+machine rather than only from the web, it is marked **[verified locally]**.
+
+## The claim under test
+
+> It is possible to create cTrader cBots directly in C# with no Windows, produce `.algo`
+> files, and run them in a container.
+
+**Verdict: true**, in two officially-supported halves — but the second half is recent
+enough that older sources (and people relying on them) say it's impossible.
+
+## The era split (why answers conflict)
+
+| Era | Build | Run on Linux |
+|---|---|---|
+| Old **cAlgo**, .NET Framework 4.x (≤ cTrader 4.1, pre-2022) | Windows-only `cTrader.exe /compile` (Spotware: *"not actually supported"*) | No |
+| Modern **cTrader Automate**, .NET 6 (cTrader 4.2+, Mar 2022) | `dotnet build` + `cTrader.Automate` NuGet — cross-platform | Desktop only at first; **Linux Docker since cTrader 5.4 (~Aug 2025)** |
+
+cTrader Desktop 4.2 (30 Mar 2022) *"removed any dependency from the cTrader application
+for the build process"* and let developers *"compile cBots and indicators using the
+'dotnet build' command and even write code and compile it on Linux or Mac."*
+
+## 1. Compiling `.algo` on Linux — CONFIRMED
+
+- **Official SDK package:** `cTrader.Automate` on NuGet, owner **spotware**
+  (Spotware Systems Ltd.). Description: *"Provides cTrader Automate SDK to build cBots
+  and Indicators in ALGO format."* Multi-targets **net6.0+** and net40, **no
+  dependencies** → installs and runs fine via `dotnet` on Linux. (Latest seen: 1.0.17,
+  2026-03-27.)
+- **Mechanism:** the package ships MSBuild `.targets`. Building a class library that
+  references it and contains an algo type (a class deriving from `Robot`/`Indicator`)
+  bundles the compiled assembly into the `.algo`. **[verified locally]** — a clean
+  `dotnet build -c Release` on this Linux box produced a valid `.algo` with **0 errors**.
+- **What you need on Linux:** just the .NET SDK + NuGet access. No Windows, no Wine, no
+  cTrader desktop.
+- **Beware the name collision:** there is a *separate* third-party NuGet package
+  `cAlgo.API` (owner `st.alexofgod`, MIT). It is **not** the Spotware SDK. Use
+  `cTrader.Automate`.
+
+### Build verified, plus a local finding
+
+- The `.algo` filename quirk: `cTrader.Automate` 1.0.17 names the output after the
+  **parent directory of the project folder** — `_AlgoFileName =
+  GetFileName(GetDirectoryName(MSBuildProjectDirectory))` in its
+  `cTrader.Automate.targets`, with no override property. **[verified locally]** Two bots
+  in one folder collide; this repo renames artifacts in `build.sh`.
+- **`.algo` format — what it actually is. [verified locally]** A built `.algo` begins
+  with the ASCII magic bytes `algo` (`61 6c 67 6f`) and is **not** a ZIP (no `PK` header,
+  no central directory). So it is Spotware's own proprietary container, not a renamed
+  archive — settling a question the web sources left open. Per Spotware it wraps the
+  compiled assembly (+ referenced DLLs, + optional source/symbols) and is encrypted; the
+  encryption algorithm is undisclosed and there is no public byte-level spec.
+
+## 2. Running `.algo` headless in a container — CONFIRMED (recent)
+
+- **Official runner:** **cTrader CLI / Console**, distributed as a Linux Docker image
+  `ghcr.io/spotware/ctrader-console` (repo `spotware/ctrader-console-docker`). Docs:
+  it *"enables traders to manage account and algo-trading operations directly from a
+  console or terminal without launching or relying on the regular cTrader application"*
+  and *"is available as a Linux Docker image … All cTrader CLI features are available
+  when using the Docker image, including backtesting."* Mount `.algo` files to
+  `/mnt/Robots`.
+- **Recency caveat:** available only in **cTrader 4.8+**, works only with **modern .NET 6
+  algos**, and the Linux image arrived with **cTrader 5.4 (~Aug 2025)**. As late as
+  **Nov 2024** a Spotware moderator wrote *"Unfortunately cTrader CLI is not supported on
+  Linux"*, and DIY Wine/Mono attempts failed. So pre-2025 sources correctly said it was
+  impossible — this is the single most likely source of disagreement.
+- The runner is a **host, not a compiler** — it runs/backtests `.algo` files; it does not
+  build them. Compilation is the `dotnet build` step above.
+
+## 3. cTrader Automate vs. Open API (don't conflate)
+
+Two different products that can both run on headless Linux:
+
+- **cTrader Automate (cBots / `.algo`)** — the strategy framework (`cAlgo.API`,
+  indicators, backtesting, optimization). Runs *inside* the cTrader runtime / the cTrader
+  CLI. This is what this repo targets.
+- **cTrader Open API** — a *separate* protocol (Protobuf over TLS/TCP or WebSocket, OAuth2;
+  endpoints `live.ctraderapi.com` / `demo.ctraderapi.com`) for **external** apps that
+  connect to a broker backend. Official SDKs: .NET (`cTrader.OpenAPI.Net`) and Python
+  (`ctrader-open-api`); language-neutral otherwise. It gives you trading + market data +
+  account access, but **no** cBot framework, indicators, or backtesting — you write all
+  strategy logic yourself.
+
+Choose **Automate + cTrader CLI** to reuse the cBot framework and backtesting on Linux;
+choose **Open API** for a fully standalone, language-flexible service.
+
+## Limitations / honesty notes
+
+- The cTrader **desktop app** is Windows/macOS only — not needed for this workflow, but
+  there is no native Linux *desktop*.
+- **Live** trading needs a broker account + cTrader ID credentials.
+- The `.algo` container is proprietary and encrypted; any legitimate Linux build goes
+  *through* the official `cTrader.Automate` package — there is no independent OSS packer.
+- cTrader's docs/tooling move quickly; version numbers above reflect mid-2026.
