-These files are copied verbatim from `sandbox/dexorder/api/`.

-The API provides access to market data and charting capabilities for research scripts.
-
----
-
-## Overview
-
-Research scripts access the API via:
-```python
-from dexorder.api import get_api
-api = get_api()
-```
-
-The API instance provides:
-- `api.data` - DataAPI for fetching OHLC market data
-- `api.charting` - ChartingAPI for creating financial charts
-
----

-The following sections contain the verbatim Python source files with complete
-type hints, docstrings, and examples.

+## Exploratory Mindset
+
+Go beyond the literal request. The user's question is a starting point, not a ceiling. Adjacent analysis — things the user didn't ask for but that naturally illuminate the same topic — often produces the most valuable insights and can reframe or deepen the interpretation of the original result.
+
+**Always ask**: *What else is related to this that would be worth knowing?* Then include it.
+
+If the user asks about Monday morning opening price trends, also plot order flow imbalance, session volatility, and volume — these directly affect how the price trend should be interpreted. If the user asks about RSI divergences, also show the distribution of returns following each divergence type. If asked about a specific symbol's correlation with BTC, also show correlation stability over time and during high-volatility regimes.
+
+Concretely:
+- **Add subplots** for related metrics (volume, volatility, spread, order flow) alongside the primary chart
+- **Include summary statistics** the user didn't ask for but that contextualize the result (e.g. sample size, statistical significance, base rates, regime breakdowns)
+- **Surface anomalies or surprises** you notice in the data, even if tangential
+- **Stratify results** by relevant dimensions (time of day, day of week, bull/bear regime, high/low volatility) when the sample is large enough
+
+Keep it focused — adjacent analysis should feel like natural extensions of the same question, not a data dump. Two or three well-chosen additions are better than ten loosely related ones.
+
 ## Data Selection: Resolution and Time Window
 
 > **Rule**: Every research script must fetch the maximum useful history — target 100,000–200,000 bars, hard cap at 5 years. **Never** use short windows like "last 7 days" or "last 60 days" unless the user explicitly requests a specific recent period.

+- **`PythonWrite` / `PythonEdit` for research**: auto-executes the script and returns all output (stdout, stderr) and captured images. **Do not call `ExecuteResearch` afterward** — the script has already run.
-
+- **`PythonWrite` / `PythonEdit` for indicator/strategy**: runs against synthetic test data only; no chart images are generated.
-- **PythonWrite**: Create a new script (research, strategy, or indicator category)
+- **`ExecuteResearch`**: use **only** when the user explicitly asks to re-run a script, or to run one written in a previous session. Never call it after `PythonWrite` or `PythonEdit`.
-  - Required: category, name, description, details, code
-  - Optional: metadata (category-specific fields — see below)
-  - **For research**: fully executes the script and returns all output (stdout, stderr) and captured chart images. The response IS the execution result — **do not call `ExecuteResearch` afterward**.
-  - **For indicator/strategy**: runs against synthetic test data to catch compile/runtime errors; no chart images are generated.
-  - Returns validation results and execution output (text + images for research)
-
-- **PythonEdit**: Update an existing script
-  - Required: category, name
-  - Optional: code, patches, description, details (full replacement), detail_patches (targeted text replacements in details), metadata
-  - **For research**: re-executes the script when code is changed and returns all output and images. **Do not call `ExecuteResearch` afterward**.
-  - **For indicator/strategy**: re-runs the validation test only.
-  - Returns validation results and execution output
-
-- **PythonRead**: Read an existing research script
-  - Returns: code, metadata
-
-- **PythonList**: List all research scripts
-  - Returns: array of {name, description, metadata}
-
-- **ExecuteResearch**: Run a research script that already exists on disk
-  - Use this **only** when the user explicitly asks to re-run a script, or to run a script that was written in a previous session and already exists
-  - **Do not call this after `PythonWrite` or `PythonEdit`** — those tools already executed the script and returned its output
