Q: What is Candleback?

Candleback (candleback.com) is Purffle's web app for backtesting trading strategies without code. You build option, futures and stock strategies — legs, strikes, stop losses, targets and re-entries — and replay them on past minute data: NIFTY, BANKNIFTY, FINNIFTY, MIDCPNIFTY, SENSEX and BANKEX options from 2019, NIFTY F&O stocks, US stocks and ETFs, and 48 forex pairs. Results show the equity curve, drawdown, a monthly heatmap and every trade, with Indian charges (brokerage, STT, exchange and SEBI fees, stamp duty and GST) included. More than 22,000 traders use it. Free plan, then Starter ₹199, Pro ₹399 and Elite ₹899 a month, with a 6-day trial of the full history and no card. It is a software tool, not investment advice.

Purffle runs Candleback, the no-code strategy backtester used by 22,000+ traders, and makes desktop apps — an AI chart analyst, a free Spotify & YouTube downloader, Claude Multi, the multi-account Claude client, and Purffle Wealth, a long-term portfolio tool — plus three indie games, 182 online tools and a free AI assistant. No ads, ever.

Four apps, up front.

Install once, keep them. Each runs on your own machine, and each has its own page with a full tour, downloads for every platform and step-by-step guides. The download counts below are live; Purffle Wealth has just launched, so its count starts from zero.

Purffle Chartwrightv1.1 · Windows · macOS beta

AI chart analysis that never invents a price.

Ask a chatbot where support is and it will make up a confident round number. Chartwright computes the structure, levels, volatility and risk arithmetic first — in about 0.2 seconds, with no language model involved — and the model may only explain figures it was handed.

01Every price computed — the model sees tool results, never raw bars.
02Explain mode puts plain English under every reading; Expert mode takes it away.
03102 indicators, six markets, eight timeframes — NSE, US equities, crypto, forex, indices, commodities.
04Screener, backtester and journal, all scored in R so they speak the same unit.

Hire the developer behind Purffle.

Alongside the free products, Chaman Raj R takes on paid work in four areas. Not an agency, not a reseller — you deal directly with the person writing the code.

01 · AI

A custom AI chatbot for your website

Not a generic bot with your logo on it — one grounded on your own docs, FAQs and catalogue, so it answers from your content instead of inventing things.

Embedded on your site, matched to your branding
Grounded on your documents
GPT, Claude, Groq, Gemini or a local model
Full source code, no monthly fee

2–7 days · proof: purffleai.comDetails & price ↗

02 · AUTOMATION

A Python script that does the boring work

If you do it more than twice a week, it should be a script. Describe the task in plain English and get an honest answer on whether it is worth automating.

Batch-process hundreds of files at once
Merge, clean and reformat Excel and CSV
Pull from any API, on demand or on a schedule
A double-click .exe if you do not use Python

1–5 days · proof: public reposDetails & price ↗

03 · DATA

Web scraping into a clean spreadsheet

Prices, directories, listings, reviews — turned into a file you can work with. Publicly accessible data only, and the site's terms are checked first.

E-commerce prices and product listings
Directories, contact lists and lead data
Pagination, filters and JavaScript pages
The scraper script, so you can re-run it

04 · SPREADSHEETS

Excel and Google Sheets that run themselves

A spreadsheet treated like a small program: structured, documented, and built so it does not break the first time somebody types in the wrong cell.

XLOOKUP, INDEX MATCH, QUERY, ARRAYFORMULA
Live dashboards, KPI tiles and pivots
Macros and Apps Script
Every formula explained in a notes tab

1–4 days · messy data is fineDetails & price ↗

“I only take work I can check myself before I deliver it.”

Your script runs on your real sample data. The spreadsheet totals get verified. The chatbot gets tested before you see it. If a job cannot be verified, it gets declined instead of guessed at.

What is Purffle?

An independent software brand from Chennai, India, founded in 2020. It runs Candleback, a no-code strategy backtester used by 22,000+ traders, and makes desktop apps (Purffle Chartwright, PurffleGrab, Claude Multi, Purffle Wealth, PurffleShorts and three trading and video tools), three indie games at Purffle Studios, 182 online tools at Purffle Tools, a free assistant at Purffle AI and non-custodial copy-trading at PurffleTrade. 96K+ downloads across 75+ countries.

What is Candleback?

Candleback is Purffle's web app for backtesting trading strategies without code. You build option, futures and stock strategies — legs, strikes, stop losses, targets and re-entries — and replay them on past minute data: NIFTY, BANKNIFTY, FINNIFTY, MIDCPNIFTY, SENSEX and BANKEX options from 2019, NIFTY F&O stocks, US stocks and ETFs, and 48 forex pairs. Results show the equity curve, drawdown, a monthly heatmap and every trade, with Indian charges included. More than 22,000 traders use it. Free plan, then Starter ₹199, Pro ₹399 and Elite ₹899 a month, with a 6-day trial of the full history and no card. It is a software tool, not investment advice.

Which Purffle apps are free?

PurffleGrab, PurffleShorts, PurffleCopyBot, PurffleTrader, PurffleVision and all three games are free, with no account and no ads. PurffleShorts, PurffleCopyBot, PurffleTrader and PurffleVision are also open source under the MIT licence. Three apps are paid, and all three are downloaded only from purffle.com. Claude Multi: Basic $5 a month (5 Claude accounts), Pro $10 (20) and Max $20 (unlimited). Purffle Wealth: Starter at ₹0, then Plus ₹149 a month, Pro ₹399 and Family ₹799 (US$ plans outside India), with a 6-day trial of Pro. Purffle Chartwright: a Free plan, then Starter ₹199 a month, Trader ₹399 and Desk ₹999, or a 7-day pass from ₹69.

What is Purffle Chartwright?

A desktop chart analyst for Windows, with a beta for Intel Macs. It has a Free plan; paid plans start at ₹199 a month. A Python engine computes swing structure, support and resistance, 102 indicators, volatility and risk arithmetic in about 0.2 seconds; only then does a language model explain those figures, and it cannot state a price no tool returned. It is educational software — not a predictor, not investment advice, and never connected to a broker. Read the full page, including what it deliberately does not do.

How do I download a Spotify playlist or YouTube video for free?

Install PurffleGrab for Windows, macOS or Linux, paste the link, pick MP3, FLAC or MP4 and download. FFmpeg and yt-dlp are bundled, so there is nothing else to install. The Spotify guide and YouTube to MP3 guide walk through it step by step. Use it for content you have the right to download.

What is Purffle Wealth?

A desktop app that keeps a long-term portfolio across Indian and US stocks, gold, silver, crypto and cash in one ledger. You write the rules it follows; it starts in paper trading, and no order reaches a broker until you approve it. Broker and exchange keys stay on your computer. Starter is ₹0; Plus, with this month's money plan, is ₹149 a month (US$5 outside India), and every account starts with a 6-day trial of Pro. It is a tool for your own decisions, not investment advice, and Purffle is not a SEBI-registered adviser. Read the full page.

How do I use multiple Claude accounts at once?

Install Claude Multi, add each Claude subscription you own and sign in once. Each account gets its own config folder, and when one hits its 5-hour limit the conversation moves to the next account that still has usage left, automatically. No API key is needed, and plans start at $5 a month. The guide also covers the manual method.

Can I automate a YouTube Shorts channel for free?

PurffleShorts is a free, open-source Python app that writes the script with any AI model, voices it with a free neural voice, adds word-synced captions and uploads or schedules it to YouTube. Set-up guide here.

What games has Purffle Studios made?

Three free titles built in Unity: Royal Hunters, a 50-player cross-platform battle royale; Purffle City Racing, an open-world driving sandbox; and Purffle Death, a psychological horror. All run in the browser and on Windows and Android. Play them at purfflestudios.com.

Do the trading bots use real money?

No. PurffleTrader and PurffleCopyBot are paper-trading tools: they read public market data and simulate trades with virtual money, so no funds are at risk and no exchange keys are needed. PurffleTrade, the platform, is non-custodial — you keep your own keys.

Can I hire Chaman Raj R for a project?

Yes — custom AI chatbots, Python automation, web scraping and Excel or Google Sheets systems, at a fixed price agreed before work starts, and only work whose result can be verified before delivery. See the services or message on Fiverr.

How do I get support or report a bug?

Email info@purffle.com. Claude Multi subscribers can also write to support@purffle.com.

Pick one. Start today.

Install an app, play a game in your browser, or open 182 tools in a tab. Most of it is free with no account. Candleback has a free plan with paid plans from ₹199, Purffle Wealth starts at ₹0 with Plus at ₹149, Claude Multi starts at $5 a month, and Purffle Chartwright's paid plans at ₹199.
