About ScripSignal

ScripSignal brings together the disclosures that promoters, directors and other company insiders are required to file with NSE and BSE, and turns them into something you can actually act on — instead of a raw filing feed you would otherwise have to trawl through one company at a time.

You can:

• Track insider trades across NSE and BSE, filtered by date range, company, transaction type (buy/sell/pledge) and mode of acquisition.
• Build a watchlist of companies you care about and see only their insider activity.
• Get AI-powered analysis of a trade or a cluster of trades, framed in plain language.
• Run pair-trading signal analysis to test how closely two stocks move together and what a spread trade between them would have returned historically.
• Track your own portfolio alongside this signal data.

Everything you see here is built from data that companies are already legally required to disclose — ScripSignal's job is to make that public record searchable, filterable and readable.

“Insider trading” refers to buying or selling a listed company's securities while in possession of unpublished price-sensitive information (UPSI) — facts like unannounced financial results, a pending merger, or a major order win that would move the stock once made public. Trading on that information before the rest of the market gets it is what the law prohibits; it is the informational edge, not the trade itself, that is the problem.

An “insider” is not limited to the CEO or promoters. It covers anyone reasonably expected to have access to UPSI by virtue of their position — directors, key managerial personnel, employees, and even outside professionals like auditors or advisors working with the company, along with their immediate relatives.

In India, this is governed by the SEBI (Prohibition of Insider Trading) Regulations, 2015. Rather than relying only on after-the-fact enforcement, the framework builds in several preventive mechanisms:

• Mandatory disclosures — promoters, directors and designated persons must report their initial shareholding and any subsequent change above a set threshold to the stock exchanges within a fixed number of trading days. This is precisely the disclosure data ScripSignal's Insider Trading tab tracks.
• Trading window closures — companies bar designated persons from trading in a window before results or other UPSI events are announced, reopening only after the information is public.
• A Structured Digital Database — every listed company must log who was given access to UPSI and when, so any leak can be traced back.
• A Code of Conduct each listed company adopts, plus SEBI's power to investigate, fine, and, in serious cases, refer matters for criminal prosecution.

In short: the trades you see in the Insider Trading tab are legal, disclosed transactions made under this framework — not the illegal kind the regulations exist to catch. Tracking them is useful precisely because insiders, even when trading lawfully, often have a better read on their own company than the market does.

Pair trading (or “pairs trading”) is a market-neutral strategy: instead of betting on whether a stock goes up or down overall, you take a long position in one stock and a short position in a second, related stock at the same time — usually two companies in the same sector whose prices have historically moved together. The bet is not on the market's direction; it is on the gap (the “spread”) between the two prices reverting back to its usual range after it widens or narrows unusually.

Building the short leg in India works differently than in some other markets. Naked overnight short selling of a stock in the cash market is not allowed for most participants — a cash-market short sale must be closed out the same day. Because of that, pair trades that need an overnight short position are typically constructed using exchange-traded derivatives instead: going long the futures (or options) of one stock while shorting the futures (or options) of the other. Both legs then sit on SEBI-regulated exchanges, subject to the usual contract specifications, margins and position limits that apply to the F&O segment.

Tax treatment follows from that structure. Gains or losses from futures & options positions — including the ones used to build a pair trade — are treated as non-speculative business income under the Income Tax Act, taxed at your regular slab rate rather than as capital gains, with turnover-based rules on when a tax audit applies. That is a different treatment from a plain, delivery-based equity investment, which is taxed as capital gains.

ScripSignal's Pair Trading tab is a research tool for the first half of this: it measures how closely two stocks' prices have tracked each other historically and simulates what a spread trade between them would have returned. It does not place trades or provide tax advice — for the derivatives mechanics and tax rules, the official sources below are the ones that govern.
