Long-form explainers on the mechanics behind the tools on this site — the charge stack on a trade, how a contract specification changes mid-life, and what an exchange calendar really says. Every figure is derived from a cited exchange or statutory document, with the date it was last checked. Educational only; no calls, no predictions.

Posts here explain mechanics and cite the document behind every number. They do not name stocks, forecast anything, or tell anyone what to do. NiftyScanner is not registered with SEBI as an Investment Adviser or Research Analyst.
The advertised brokerage figure is the one item on a contract note that does not move with the size of the trade. Everything else does — and each charge is levied on a different base, on a different side of the trade, and in some cases only in one segment. Knowing which is which is what lets you read a contract note instead of trusting a summary line.
Brokerage is flat per order; the statutory charges are proportional — so cost as a share of turnover falls as the ticket grows and never reaches zero.
GST is not 18% of your total cost. It applies to a defined subset of the charges, and STT and stamp duty sit outside it.
Intraday and delivery are charged on different bases, not just at different percentages.
NiftyScanner provides general educational information and user-input mathematical utilities. It does not provide personalised investment advice, research recommendations, trade calls, price targets or suitability assessments. Market-calendar, settlement and transaction-cost information may change and should be verified against current official exchange, clearing, broker, depository and tax records. Trading and investing involve risk; you remain responsible for your own decisions and should seek appropriately qualified professional advice where needed.
