Plain email is always fine and is usually faster than the form. Attachments are welcome for research correspondence.
What gets a quick answer
- Corrections and factual disputes about anything published here.
- Methodological questions — why a particular null, why that cost assumption.
- Scoping conversations for research or tooling work.
- Teaching, workshop and conference enquiries.
What will be declined
- “What do you think of” a specific instrument or position.
- Requests for signals, tips, entries, exits or price targets.
- Requests to manage, advise on or review your capital.
- Requests to build, sell, license or share an automated trading system.
- Broker, platform and affiliate partnership proposals.
These are declined regardless of fee. If you want a view on your own situation, that is what a licensed adviser is for.
Please do not send confidential or personal financial information. Email is not a secure channel. Never include account numbers, credentials, API keys or holdings in a message to this address. Correspondence does not create an adviser–client relationship of any kind.
