This course is written by one person and it will contain mistakes. Finding them is a favour, not a complaint. Every message here is read.
The most useful message names one specific thing: which lesson, which line, what it says, and what it should say. A wrong rupee figure, a chart that disagrees with the paragraph beside it, a strike that does not add up, a claim about margin or tax that is out of date. Second most useful: the topic you came here looking for and could not find.
What we cannot answer is the one thing people most want to ask. No views on what to trade, no opinion on a position you are holding, no strike suggestions. Not modesty: that is advice, we are not registered to give it, and the disclaimer explains why the line matters.
If you would rather not use a form, the same messages reach the same inbox at rohan@optionsgyan.com. Screenshots are welcome and often faster than describing the problem.
Everything below is a real change to the course. When a correction comes from a reader, their name goes beside it if they want it there.
The page claimed that no data was sent anywhere. Anonymous usage analytics do run on the site, so the line now says only that what you type into a calculator stays in your browser, which is the part that is actually true.
Every NIFTY example moved to a 65-unit lot, and roughly forty rupee figures across the lessons, charts and calculators changed with it.
Weekly expiry was taught as Thursday. NSE moved it to Tuesday in late 2025, so the lesson was rewritten and retitled rather than patched.
It is not a forum, and for now that is deliberate. A public board attached to a trading site fills up with tip-sellers and Telegram links faster than one person can clear them out, and Lesson 13 spends an entire lesson explaining why those people are not your friends. Hosting a room for them would be an odd way to end the argument. If enough people want somewhere to talk, that gets built properly, with someone actually minding it.
