Contact

Write to [email protected]. Every message is read. Replies take longer than a live chat would, so for anything urgent about an open position, call your broker's support line, and for a prop firm account, the firm's own support.

Corrections

Include the page address and the sentence, figure or step you think is wrong. For a worked example or a quiz question, say which line of the arithmetic gives you a different answer. For a fund on one of the ETF lists, say what the fund's own page shows. Confirmed errors are fixed on the page and the updated date changes, as the editorial policy describes.

Questions and suggestions

Questions about how an indicator is calculated or how a calculator works are welcome, and so are suggestions for strategies, terms or courses not covered yet. Look through the guides and the definitions first, since the answer may already be there.

Getting a useful answer

A question about a number is easiest to answer when it comes with the numbers. If a calculator gives a result you did not expect, send the inputs you typed and the output you got. For a prop firm rule, quote the rule's wording from the firm's page, because firms phrase the same idea in different ways. For a Social Security question, the figures on your own statement from the Social Security Administration settle most of it.

What cannot be answered

Requests for advice on a specific stock, trade, account, claiming decision or tax filing cannot be answered. Nobody here knows your situation, and a reply would amount to personal financial advice; the risk disclaimer explains why. For questions about an account, contact the firm that holds it. For a complaint about a registered firm, FINRA and the SEC both take complaints from investors.
