This site is run by one person. Mail arrives at chwoo2331@gmail.com and is read by the same person who wrote the engine, so there is no support queue to get lost in and no form that goes nowhere.

What is worth writing about

• A number that looks wrong. Include the share link from the Share button — it encodes the whole strategy, so the exact run can be reproduced.
• An indicator or exit rule that is missing. Say what you would test with it; that is what decides the order things get built.
• Something that reads wrong in your language. The site is in English, Korean, Japanese and Chinese, and only the first two were written by a native speaker.
• A guide that is unclear or mistaken. Corrections are welcome and get credited in the changelog.

What to expect

Feedback is collected and worked through in batches roughly every two weeks, so a reply may not be immediate. A bug that produces wrong numbers jumps the queue, because a backtester that reports the wrong result is worse than no backtester.

What this address is not: it is not investment advice, and no strategy will be reviewed or recommended for you. The tool is here so you can test your own ideas skeptically.
