Contact and corrections
One channel, and it exists mainly for one job: telling us where a lesson is wrong, so it can be checked against the primary source and fixed.
Reporting an error
You are part-way through a lesson on transaction charges, you open your own contract note to follow along, and the figure on the screen does not match the figure you actually paid. That is the moment this page exists for. Either the lesson is wrong, or the rule has changed since it was written, and both need the same thing from you.
- The lesson URL. The full address of the page, not the lesson title — there are several hundred lessons and titles repeat across tracks.
- The exact sentence. Pasted, not paraphrased. It is the fastest way to find the claim in the source file, and paraphrase quietly loses the qualifier that was the problem.
- What you believe is correct, and where that comes from — the circular, the section of the Act, the exchange page, your own contract note. A source turns a correction into something that can be checked in minutes rather than argued about.
- The date, if it matters. A rate that was right in one financial year and wrong in the next is a different fix from a rate that was never right.
Numbers get priority over prose. Rates, thresholds, section numbers, deadlines and arithmetic are the claims a reader is most likely to act on and the ones that age fastest, so they go to the front of the queue.
What happens to a correction
The claim is checked against the primary document rather than against another website, because secondary commentary is how most wrong figures propagate in the first place. If the lesson is wrong it is changed, and the revision date on the about page moves with it.
If the rule changed rather than the lesson being mistaken, the fix is usually larger than swapping a number. The lesson gets rewritten towards the mechanism — why the charge exists and what it is levied on — so that the next revision to the rate does not silently make it wrong again. That is the standard the whole curriculum is meant to hold to, and a correction that exposes a lesson leaning on a figure instead of a mechanism is the most useful kind to receive.
What this channel cannot do
Market Vidyalaya is an educational publisher, not a SEBI-registered investment adviser or research analyst. Questions of the form “should I buy this”, “is my portfolio sensible”, “what will this stock do” or “how much tax will I owe on my sale” cannot be answered here, and the reason is not modesty: an answer to a specific person about their own money is advice, and advice is a registered activity. See the disclaimer for the full position, and the lesson on choosing a fee-only registered adviser if that is what you actually need.
A complaint about a broker, depository participant, mutual fund or registrar also does not belong here, and sending it here costs you time you may not have. Those complaints follow their own escalation ladder: the intermediary’s own designated grievance officer first, in writing and with the ticket reference kept, then the exchange or the relevant regulator’s complaint platform if it is not resolved. The lesson on investor protection and grievances walks through each rung and what evidence each one wants.
Other things worth writing about
- A calculator that misbehaves. The inputs you used and what you expected, so it can be reproduced. Every calculator runs in your browserruns on your device, so the numbers you entered are the whole bug report.
- A dead link or a missing page. Including where you were when you clicked it.
- A term the glossary should define. Especially one you met on this site and had to look up elsewhere — that is a gap in the writing, not in you.
- Anything unusable. Contrast, keyboard navigation, a screen reader reading a chart as nonsense, text that will not reflow on a small screen.
- Permission to teach with it. Usually already granted — the terms of use allow classroom and study-group use with attribution, so ask only if what you have in mind goes further.
Why there is no form
A contact form needs a server to receive it and somewhere to store what it receives. This site has neither, which is the same reason it has no accounts and no database, so email is the honest option rather than a form that quietly ships your message to a third party.
The consequence is worth stating: writing to us means your address sits in that inbox, because that is how email works. It is not added to a mailing list, since there is no list and no system capable of holding one. The privacy policy covers everything else the site does and does not hold.
