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-backtest 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 10d 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.

What it actually says

Lona Backtest Workflow

Execute a complete backtesting workflow: select or create a strategy, ensure market data is available, run the backtest, and analyze results.

Steps

  1. Check existing strategies - Use lona_list_strategies to see available strategies
  2. Select or create strategy - Either pick an existing strategy or create a new one:
    • From code: lona_create_strategy
    • From description: lona_create_strategy_from_description (async, poll with lona_get_strategy_creation_status)
  3. Check market data - Use lona_list_symbols to see available data
  4. Download data if needed - Use lona_download_market_data to get data from Binance
  5. Run backtest - Use lona_run_backtest with the strategy ID and data IDs
  6. Monitor progress - Poll lona_get_report_status every 5-10 seconds until COMPLETED or FAILED
  7. View results - Use lona_get_report for summary or lona_get_full_report for detailed analysis
  8. Visualize trades - Use lona_get_report_chart to see trade entries/exits

Ask the user

  • Which strategy to test (or describe one to create)
  • Which market/symbol to test on
  • What date range to backtest
  • Any specific parameters (initial cash, commission, leverage)

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.
