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

strategy-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.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Strategy backtest

The sequence

  1. strategy_compare symbol=… — nine built-in strategies over the same bars, ranked. This is the cheap first pass: it tells you whether anything on this symbol has an edge worth testing properly, and the bars are fetched once for all of them.
  2. backtest symbol=… strategy=… on the one or two that stood out. Set walk_forward=true and give it folds. An in-sample result on two years of daily bars is a description of the past, and presenting one as a strategy is the single most misleading thing this server can be used to do.
    • Set commission_buy_pct and commission_sell_pct to the user's real fees. IDX defaults are roughly 0.15% buy and 0.25% sell, and the difference between gross and net is where most paper edges live.
    • stop_loss_pct, take_profit_pct and max_hold_bars change the answer more than the entry rule usually does.
  3. pine_script symbol=… kind=strategy to hand it to TradingView, with the entry and exit conditions carried across.

workflow_run name=strategy_check and name=pine_handoff package steps 1–2 and 3.

What to report, and what not to

  • warnings and inconclusive are the result, not a footnote. Read them out. If the backtest says the sample was too small, that is the answer to the user's question.
  • ARA/ARB-locked bars break fills. A limit-up day has no liquidity at the printed price. The backtester flags these; a strategy whose returns come from limit-locked entries did not happen.
  • Two years of daily bars is about 480 sessions. That supports claims about daily setups. It does not support a claim about monthly seasonality, and it does not survive being sliced by regime.
  • Trade count matters more than return. Nine trades with a 60% win rate is not a 60% win rate.
  • Never annualise a backtest or extrapolate it forward.

Presenting it

Give the net return after commission, the trade count, the maximum drawdown, and the walk-forward folds side by side — if fold three lost money, that belongs in the first paragraph. Then the warnings. Then, plainly: backtested results do not predict future returns, and this is not advice.

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.
