Requirements

Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 5156f81. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- open.bymadata.com.ar
Also links to:
- byma.com.ar
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Byma loads about 3.9k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 1,163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~81
When it runs · the whole SKILL.md, loaded when a task matches: ~3.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

🔒 Nota sobre certificado SSL

BYMA presenta un certificado SSL cuya CA intermedia no esta incluida en el bundle certifi estandar de Python. Esto causa:

SSLError: CERTIFICATE_VERIFY_FAILED

El script usa verify=False — la conexion sigue siendo TLS-encriptada pero se omite la validacion de cadena. Es el patron estandar de las librerias publicas de BYMA (pyhomebroker, bymadata, etc.).

Si preferis no usar verify=False, podes instalar el cert intermedio de BYMA en tu trust store del sistema.

Convenciones de simbolos

Historicos: formato `TICKER 24HS`

⚠️ TODOS los historicos requieren el sufijo 24HS (con espacio). Sin sufijo retorna HTTP 400. El sufijo CI tambien retorna 400 (no soportado). 48HS retorna 200 con 0 puntos.

Tipo	Ejemplo
Accion	`GGAL 24HS`, `ALUA 24HS`, `YPFD 24HS`
CEDEAR ARS	`AAPL 24HS`, `MSFT 24HS`
CEDEAR USD	`AAPLD 24HS`, `MSFTD 24HS`
Bono soberano ARS	`AL30 24HS`, `GD30 24HS`, `AE38 24HS`
Bono soberano USD MEP	`AL30D 24HS`, `GD30D 24HS`
Bono soberano CCL	`AL30C 24HS`, `GD30C 24HS`
LECAP/BONCAP	`TY30P 24HS`, `TZX26 24HS`

Bonos: convencion de sufijos por moneda

Sufijo	Variante	Ejemplo
(sin)	ARS — paridad en pesos	`AL30`
`C`	CCL (Contado con Liquidacion / EXT)	`AL30C`
`D`	USD MEP	`AL30D`
`X`, `Y`, `Z`	otras variantes (intra-day, settlement alt.)	`AL30X`

Indices conocidos

Codigo	Indice
`M`	S&P MERVAL
`G`	BURCAP

Otros codigos (A, B, V, etc.) son aceptados pero retornan series con todos ceros — probablemente indices deprecated.

Filtros comunes en POST paneles

Filtro	Descripcion
`T0=true`	Solo `settlementType=1` (CI / Contado Inmediato)
`T1=true`	Solo `settlementType=2` (24hs)
`T2=true`	Solo `settlementType=3` (48hs — practicamente vacio)
`page_size=5000`	Trae todo el dataset en una sola llamada (recomendado para `public-bonds` y `senebi-on`)

⚠️ El parametro page (numero de pagina) es ignorado por la API — siempre devuelve pagina 1. Workaround: usar page_size grande o flag --all.
