ProStocks is the trading brand of Sunlight Broking LLP — a Mumbai-based SEBI-registered discount broker and CDSL depository participant founded in 2015. While it does not have the client base or brand recognition of Zerodha, Groww, or Angel One, ProStocks has built a loyal following among one very specific group: high-volume active traders who execute large numbers of trades every month. The reason is simple — ProStocks offers India's most competitively priced unlimited trading plan at ₹899/month for unlimited equity and F&O trades, which is lower than any equivalent plan from larger brokers.

On the standard flat-fee plan (no monthly subscription), ProStocks charges ₹0 on equity delivery and ₹15 per executed order on intraday, F&O, and currency — cheaper than Zerodha's ₹20. The Call & Trade charge for intraday/F&O is just ₹10 per executed order — the lowest in the industry. Critically, ProStocks does not charge PCM (Proprietary Client Margin) fee — a hidden charge that many brokers embed into transaction charges. This makes ProStocks' effective transaction costs genuinely lower than most peers on a like-for-like basis.

The limitations are equally specific. ProStocks does not offer commodity trading (MCX/NCDEX). The platform, while functional, lacks the polish and feature depth of Zerodha Kite or Fyers. It is a niche broker — ideal for cost-conscious active traders, but not the right first choice for beginners, mutual fund investors, or those who need research guidance.

ProStocks has a uniquely simple pricing structure for a discount broker: one standard flat-fee plan and four unlimited subscription plans (monthly and yearly variants for equity and currency). The unlimited plans follow the calendar month — they are billed via contract notes at 2.5% of trade value as trades are executed, and once the monthly cap is reached, all remaining trades in that month are free. If no trades are placed in a month, no plan brokerage is charged for that month.

All charges verified against prostocks.com/charge-list.html (official charges page) as of March 2026.

ProStocks STAR is the primary trading platform available via web browser (starweb.prostocks.com), mobile app (Android/iOS), and a co-location version for high-frequency traders (starcolo.prostocks.com). The interface is functional and clean but noticeably less polished than Zerodha Kite, Groww, or Fyers. It serves the purpose for active traders: real-time quotes, fast order entry, multi-segment coverage, and margin calculation. The platform prioritises function over aesthetics — experienced traders adapt quickly while beginners may find it less intuitive than consumer-first apps like Groww.

A downloadable installable desktop trading terminal designed for frequent traders who need professional-grade tools: tick-by-tick intraday charts, live streaming quotes, multiple markets and segments in the same window, and quick keyboard-based order entry. Particularly popular with high-frequency intraday traders who use the unlimited plan. The NSE NOW platform is also supported as an alternative for NSE traders.

ProStocks offers the Star API for algorithmic trading with documented endpoints and an SDK on GitHub. It is functional and free to access. Documentation quality is adequate for experienced developers but less comprehensive than Zerodha's Kite Connect or Fyers' API. The combination of the API with the ₹899 unlimited plan is particularly attractive for retail algo traders who execute high volumes — effectively zero brokerage after breakeven on a monthly subscription.

ProStocks offers 100% online account opening for KRA and IPV-compliant customers. Activation is typically same-day for documents submitted on working days.

• You are a high-volume active intraday or F&O trader — ₹899/month unlimited equity plan means zero brokerage after the 60th trade. Average active traders report 60%–99% savings on brokerage vs standard ₹20/order brokers.
• You primarily do delivery investing (no monthly subscription needed) — ₹0 delivery brokerage on the standard plan, ₹0 AMC, and a low ₹13.50 DP charge make ProStocks genuinely cost-competitive for delivery investors alongside Zerodha.
• You are an NRI looking for a low-cost flat-fee broker — PIS and Non-PIS NRO accounts available at ₹15/order brokerage on the flat-fee plan.
• You build algo systems and want API access with unlimited brokerage — API + ₹899 unlimited plan = effectively free trading after breakeven for algo traders.

• You trade commodities — no MCX/NCDEX. Use Zerodha, Angel One, or Fyers instead.
• You want to invest in mutual funds — no MF platform. Use Groww or Zerodha Coin for direct MF.
• You are a beginner — the platform lacks the consumer-first polish of Groww or Zerodha Kite. Start there and migrate to ProStocks when trading volume justifies the unlimited plan.
• You trade on both NSE and BSE — unlimited plans are per exchange. Two exchanges = two subscriptions = ₹1,798/month for unlimited on both.
• You need research or advisory — ProStocks provides no research, tips, or recommendations. Angel One is the only flat-fee broker with free research.
