India's first systematic investing terminal: models optimised with AI and machine learning, rules frozen before they run, every order and fill on record. * **AI and ML**model optimisation * **Tick by tick**every order and fill * **NSE, BSE**data and execution [Sign up for RupeeCase](https://invest.rupeecase.com/signup)Open the engine 01Research lab ## Build. Test. Then publish. The same lab that builds the strategies: pick a universe, set the rule, read the history. 02The engine ## From the exchange to your broker. 1. **03**Data from NSE and BSEPrices, corporate actions, constituents. 2. **03**Data from NSE and BSEPrices, corporate actions, constituents. 3. **03**Data from NSE and BSEPrices, corporate actions, constituents. Machine learning searches. The rule that ships is frozen. The optimiser, sample data A design story of the research process. The optimiser searches candidates; only a rule that survives out of sample tests and costs is frozen and published. The screen that scores and orders the universe.

Execution is through your own SEBI registered broker. 03You approve, it executes ## One tap. Your broker places it. On each rebalance the rule lists what goes in and what goes out. You approve; the orders go to your own broker, and every fill comes back to your order log. Recorded, sample data 04The tape ## Every entry and exit, as published. Replayed from the published model rebalance record: BUY is a name that entered, SELL a name that left. Your own orders and fills, with prices and times, sit in your order log. DateStrategySideSymbol 05The wealth engine ## Everything your money does, in one place. Swipe through the terminal. Recorded and captured on sample data. ←→ Smart ledger ### Every rupee in and out, dated. Money in and out, charges and turnover, per portfolio. Order tracking ### Each order, sent to filled. Every order with the fill your broker returned. Portfolio analysis ### Risk, rolling returns, drawdowns. Rolling Sharpe and Sortino, risk heatmaps and drawdowns on your actual result. Your portfolio ### The actual result, from day one. Your own portfolio from the date you invested, never mixed with the model history. Research lab ### Build an index from a universe. Pick a universe, set the rule, read its history. Pledge for margin ### Your holdings can work twice. Pledge eligible holdings at your broker and trade on your own. Margin carries risk; haircuts and terms are set by your broker and the exchange. A rebalance running, sample data 06Transparency ## Nothing executes in the dark. * **Every order,** with the time it was sent and the fill your broker returned. * **Every model rebalance,** published with what came in, went out and stayed. * **Every fee,** 0.2% of traded value, shown per rebalance. * **Your actual result** from the day you invested, never mixed with the model history. 07Questions ## The engine, answered. How the technology works, in plain words. ### How does RupeeCase use AI and machine learning? Machine learning is used in research to search and optimise the model behind each strategy: which signals rank the universe, how many names to hold and how often to rebalance, tested out of sample. The rule that ships is then frozen and published, so the live strategy is a fixed, readable algorithm, not a black box that changes on its own. ### What does tick by tick execution transparency mean? Every order the rule generates and every fill your broker reports is recorded with its time, price and quantity in your order log, and every model rebalance is published with what came in, what went out and what was held. Nothing executes in the dark. ### Where does the market data come from? Prices, corporate actions and index constituents from NSE and BSE. Back tests deduct brokerage, STT, exchange charges and GST. ### Can I pledge my holdings for margin? Pledging happens at your broker: you can pledge eligible holdings to create margin and trade on your own through your broker account. RupeeCase shows it alongside your portfolio. Margin carries risk, and haircuts and terms are set by your broker and the exchange. ### What is the smart ledger? A running record of every rupee in and out of each portfolio, every order, fill, fee and rebalance, dated, so your actual result from the day you invested is always separate from the model history. 08Next ## See it at work.
