A Trendlyne alternative where every scan is a backtest
Trendlyne is the rare Indian platform that backtests screeners at all — and it meters the feature: roughly 200 backtests a year on GuruQ, 1,200 on StratQ, none on the free tier. If what pulled you to Trendlyne was testing scans rather than reading analyst data, that meter is probably why you are here. On PatternsRadar the replay is not a feature you spend; it is attached to every scan, free tier included, and runs in about 90 milliseconds.
| Capability | PatternsRadar | Trendlyne |
|---|---|---|
| Scan-level backtesting | Every scan, unmetered, ~90 ms | Yes — quota-metered (~200/yr on GuruQ, ~1,200/yr on StratQ), paid only |
| Backtest configurability | Fixed 250-session replay, 1/5/20-day close-to-close returns | Custom date ranges, universe and benchmark — more configurable |
| Fundamentals, analyst estimates, shareholding | Headline fields only — P/E, market cap, growth, promoter/FII/DII holding, point-in-time (coverage still backfilling); no analyst data or scores | 3,000+ parameters, DVM scores, Forecaster |
| F&O data | Per-stock scan fields — futures OI, OI change, basis, put-call ratios — backtestable | Full F&O dashboards and analytics |
| Query model | Sift — a readable query language with event operators | Parameter/dropdown builder, plus an AI screener creator |
| Event conditions (crossed above within, has been above for) | Yes | No |
| Delivery % screening | Scannable and backtestable | Scannable, incl. multi-window averages |
| Intraday data | No — end-of-day by design | Live data; 15-min screener alerts on StratQ |
| Split-adjusted daily history | 30 years, any past session scannable | Long history; some parameters not backtestable for lack of it |
| REST API + MCP for agents | Every plan, including Free | No public API — Excel Connect and downloader on paid tiers |
| US markets | No | On Pro/Pro Plus plans |
| Entry price for backtesting + alerts | ₹400/month | ₹310/month (GuruQ) |

The differences that matter
Metered testing changes how you test
A backtest quota makes each test a small spending decision, and the scans that get tested are the ones you already believe in. Unmetered replay inverts that: testing a half-idea costs nothing, so the setups that die in the data die in an afternoon instead of in your account. Trendlyne's backtester is genuinely more configurable — custom dates, universes, benchmarks — and for portfolio-style questions it is the better instrument. For the tight loop of write-a-condition, check-it, revise-it, the meter is the difference.
Dropdowns and sentences answer different questions
Trendlyne's builder covers three thousand parameters, which no query language matches for breadth. What a parameter list cannot say is sequence: crossed above the average within three days, has held above it for ten, rising for five. Those are sentences about time, Sift states them as written, and they are the conditions swing setups are actually made of.
An API on every plan, or an Excel download on paid ones
Trendlyne's programmatic story is Excel Connect and a data downloader, on paid tiers. PatternsRadar exposes a REST API and an MCP server on every plan including Free — an agent like Claude can write and run scans directly. If your research ends in a spreadsheet, both work; if it ends in a script or an agent, only one does.
Which should you use?
When Trendlyne is the right choice
Choose Trendlyne if the research is the point: fundamentals beside technicals, analyst forecasts, shareholding patterns, DVM scores, F&O dashboards, US markets — and live intraday data with 15-minute alerts. As an all-in-one Indian research platform it has no equal in this comparison, and its configurable backtester suits longer-horizon, portfolio-style questions.
When PatternsRadar is the right choice
Choose PatternsRadar if the scan is the point: you know the setups you want, you want them written readably, and you want every one tested before it earns attention — without counting backtests. The delivery field, futures OI and put-call ratios as scan conditions, point-in-time P/E and shareholding, the 30-year history, and the API/MCP access come with it, from ₹0.
Common questions
Is PatternsRadar a free alternative to Trendlyne?
For technical screening, yes: the whole scan library, the query language, 30 years of history and unmetered backtest replay are free with no account. It does not replace Trendlyne's research side — PatternsRadar has fundamentals as screening fields (P/E, market cap, growth, shareholding, still backfilling), but no analyst estimates, DVM scores or research pages, and no intraday data.
What does Trendlyne have that PatternsRadar doesn't?
A great deal, honestly: 3,000+ screening parameters spanning fundamentals, shareholding and analyst data, proprietary DVM scores, live intraday prices, 15-minute alerts on StratQ, US market coverage, and a backtester with configurable dates, universes and benchmarks. PatternsRadar is deliberately narrower — NSE technicals, end-of-day, tested.
Can I backtest scans without a quota?
Yes — that is the core difference. Every scan on PatternsRadar carries a hit-rate replay over the last 250 sessions, free tier included, with no annual count. It is a sketch (close-to-close, no costs) rather than a configurable backtest, and the pages say so; but you can run it a thousand times a day without spending anything.
