# Tark > Tark is decision intelligence for discretionary traders in Indian markets (NSE, BSE, F&O), by Atlas Finlabs. One terminal to scan, analyse and decide on a trade, with AI that shows its work — the evidence behind a verdict, where each number came from and how fresh it is. Tark reduces a trader's uncertainty; the trader makes the decision. It is a decision-support tool, not investment advice. ## What Tark does - Decision reads: a single verdict on an instrument (Wait, Act or Strong) with the evidence weighed and the holding horizon it was scored on (intraday, swing, positional). No calibrated probability is shown until one exists. - Options: the option chain read for the setup in front of you — IV regime, open-interest shifts and the strikes that matter. - Scanners: intraday and swing scanners that surface a signal only when it carries information, rather than firing across the whole market. - Tark AI: ask in plain English. The model does not touch raw data; it orchestrates the same engine the terminal shows, so answers stay grounded, and it says so when it cannot source a number. - Desk, journal and alerts: plan a trade, monitor it against the plan, and review it afterwards. ## What Tark refuses to do - It does not give tips or tell anyone to buy or sell. - It does not invent probabilities or confident predictions. - It does not place a trade without the trader's explicit action. ## Who it is for Discretionary traders in India — F&O, intraday and swing — including people who trade alongside a full-time job. Sign-in is with Google; there is a free plan. A broker account (Zerodha, Angel One, Dhan and others) can be connected for live data and order placement. ## Links - [Home](https://tark.atlasfinlabs.com/): what Tark is and how it works - [Request early access](https://tark.atlasfinlabs.com/early-access) - [Sign in](https://tark.atlasfinlabs.com/login) - [Terms](https://tark.atlasfinlabs.com/terms)
