What Stretus is
Stretus is a platform for building, testing and running your own systematic trading rules. Six things, precisely.
1. A strategy compiler that reads plain language
You describe a trading rule in ordinary words. A language pipeline reads your words, extracts the specific values you stated, compiles them into a formal strategy object, and shows you that object before it runs anything.
The compilation is deliberate about what it does not do. When a phrase carries no threshold, it asks. When a phrase is genuinely ambiguous, it asks rather than picking a reading. When the platform has no field that can hold what you asked for, it says so instead of substituting an approximation. Four refusal categories, one behaviour each. See How the AI reads your words and AI limitations.
What this is not: a search for a good strategy. The platform builds what you asked for. It does not evaluate whether the idea is a good one.
2. A backtester that charges you what trading actually costs
Every strategy can be run over historical market data. The simulation applies slippage, per-venue commission, and, in Indian markets, securities transaction tax, stamp duty, exchange transaction charges, the SEBI turnover fee and GST on the fee components. The cost model is versioned so results produced under different statutory rates can be told apart. Full schedule: Fees & charges.
What this is not: a prediction. A backtest measures how a rule would have behaved on data that already happened. See Backtest limitations.
3. An execution engine with enforced capital boundaries
A deployed strategy gets its own capital allocation and cannot exceed it. Two of the execution risk checks, available capital and the allocation ceiling, cannot be turned off. Seven more are available and are off until you configure them, which is the single most important thing to know about the risk system. Every gate, its unit and its default: The nine order gates.
What this is not: a guarantee against loss. A risk gate blocks an order that breaches a limit you set. It does not close an open position, and it cannot prevent a market gapping through your stop.
4. Two isolated execution modes
Paper fills orders in an internal simulator against live prices. Nothing leaves the platform, no broker connection is needed, no capital is at risk. Live routes orders to your own connected broker or exchange. The two paths share a strategy definition and share nothing else, separate capital, separate positions, separate history. See Paper vs live.
5. Research screens that surface market conditions
A suite of screens scan the market for technical conditions and present what they found: instruments where a defined pattern is currently present, with the trigger level and the level that would invalidate it, plus the evidence behind the score. Each one names its scoring formula and states in the product that its score measures pattern strength, not expected profit. See Discovery & research.
What this is not: a list of what to buy. The screens report a measured condition. Whether that condition is worth trading, at what size, with what stop, and whether at all, is yours to decide.
6. A place to publish a strategy, and to run one someone else published
A strategy you built can be published so other users can find it and run it on their own account. Running a published strategy clones its rules into your account. You allocate your own capital, you deploy through your own broker, and the author never sees your account. The author's later changes do not reach your copy. See Community & strategy sharing.
What this is not: following someone's trades. There is no mirroring, no signal relay from another person's live positions, and no shared account. You are running a copy of a rule set, under your own controls.
