If something on this site is wrong, tell us and we will fix it. Every page cites its sources precisely so a claim can be checked, and a correction is worth more to us than a compliment — on a site about risk, being wrong in public is the one thing we cannot afford.

Useful things to include: the page, the claim, and what you think the right answer is. If you can point at a primary source, better still.

What we cannot answer

We do not give personal trading advice, and we will not tell you whether to take a particular trade, which broker suits your circumstances, or how to size a position in your account. That is not modesty — it is the line between education and advice, and it is the line this site is built on. What we can do is explain the mechanics and point you at the arithmetic.
