Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lona-trading-strategy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Trading Strategy Development

You have access to Lona's trading strategy tools for creating and managing algorithmic trading strategies using the Backtrader framework.

Available Tools

Strategy Management

  • lona_list_strategies: List all saved strategies with metadata (name, ID, description, version)
  • lona_get_strategy: Get strategy details (name, description, version, language, timestamps)
  • lona_get_strategy_code: View the Python Backtrader source code of a strategy
  • lona_create_strategy: Create a new strategy from existing Python Backtrader code
  • lona_update_strategy: Modify an existing strategy's name, description, or code. Returns a NEW strategy ID (versioning)

AI Strategy Generation

  • lona_create_strategy_from_description: Generate a strategy from a natural language description (async — returns jobId)
  • lona_get_strategy_creation_status: Poll the async creation job for progress

Strategy Code Requirements

All strategies must use Python with the Backtrader framework:

  • Import: import backtrader as bt
  • Inherit from bt.Strategy
  • Define parameters using tuple format: params = (('name', default_value),)
  • Implement __init__ for indicators and next for trading logic
  • Use self.buy(), self.sell(), self.close() for order execution
  • Access data via self.data.close[0], self.data.open[0], etc.

Workflows

Create a strategy from Python code

  1. Write Backtrader-compatible Python code
  2. Call lona_create_strategy with name, description, and code
  3. Receive a strategy ID for backtesting

Generate a strategy with AI

  1. Call lona_create_strategy_from_description with a clear natural language description
  2. Receive a jobId immediately
  3. Poll lona_get_strategy_creation_status every 10-15 seconds
  4. Status pipeline: PENDING -> GENERATING -> SAVING -> COMPLETED/FAILED
  5. When COMPLETED, receive the strategyId, generated code, explanation, and quality review
  6. Typical creation time: 3-5 minutes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
