4 year PnL available on request.
How It Works
Put your portfolio to work in three steps.
The same capital, working twice. Your investments stay invested while the value they hold unlocks new opportunity.
Step 01
Buy, hold, or transfer eligible investments
Keep building the portfolio you already believe in. Mutual Funds, ETFs, Debt Funds, Bonds, and more.
Tap to pledge
Step 02Pledge these investments
Pledging unlocks additional trading capital, a strategy long used by institutions, now open to individual investors.
Step 03
The generated margin powers automated trading
The portfolio continues to grow, while the margin is put to work in the markets.
Why We Are Different
Two engines, one tank of fuel.
Traditional approaches run a single engine and burn the fuel once. StoneBridge runs both from the same tank, so one pool of capital does two jobs at once.
Engine 2
Conventional Trading
- Trade with cash
- Trading capital seeks returns
- Cash stays locked for trading

Engine 1 + Engine 2

What our clients say
Backed by people who stay.
More than a service. A relationship.
I was a Trade Automation user with marketfeed for over 3 years, and when the service stopped, I was unsure about trusting another platform. Since this new platform was started by former team members from marketfeed, whom I had known from the beginning, I felt confident continuing with them. The support has been excellent, and everything has been running smoothly, just like before. Overall, it has been a very reliable experience.
Dr. Renith Mathew PeterIdukki, KeralaBeing a software engineer, managing work and trading at the same time was always challenging for me. This automation platform has been extremely helpful in solving that problem and has made trading completely tension-free, as both funds and trades remain in my own account with 100% transparency. With StoneBridge Research, trading has become completely passive and hassle-free.
Sachin MathewUAEAs a freelancer, I was looking for platforms that offered both reliability and value, and that's when I came across StoneBridge. Their onboarding process was smooth and hassle-free, making it quick and easy to get started. What truly stands out is their commitment to delivering value to customers. The platform is well managed, and I particularly appreciate the transparency offered through their dashboard, where I can monitor performance and activity at any time. The team has been supportive and responsive throughout, making the entire experience seamless.

Answers, before you ask.
If something here doesn't answer your question, drop us a line below.
Yes, currently we only support IIFL Securities. If you don't have an IIFL account, we'll help you open one during onboarding. We do not support Zerodha, Angel One, Upstox, or other brokers at this time.
Entirely in your own IIFL Securities trading account. StoneBridge has order-placement authorization through IIFL's broker API, but no withdrawal access and no custody of client funds. You can withdraw or close your account directly with IIFL at any time.
No. Automated trading carries the same market risk as discretionary trading, sometimes more. Past backtest or live performance of any strategy does not guarantee future results. You may experience losses, including substantial drawdowns. You should only deploy capital you can afford to risk.
StoneBridge Research is a technology platform provider. We are not a SEBI-registered Investment Advisor, Research Analyst, Portfolio Manager, or Stockbroker. Our strategies are systematic rule-based programs that execute through IIFL's regulated brokerage API. They are not investment advice or buy/sell recommendations.
The strategy logic itself (entries, exits, stop-losses, position sizing rules) is rule-based code. Layered on top of that, our team runs an oversight function: we monitor live strategy behaviour, adjust risk parameters as volatility regimes shift, refine strategy logic over time, and can pause a strategy during extreme events such as major news, gap-risk windows, or technical anomalies in the market. This is operational management of the strategy as a system. It is not personalised investment advice to individual users. Every subscriber on a given strategy runs the same rules, with the same risk overlays, at the same time.
Yes. You can disable any strategy from the dashboard at any time. Open positions will continue to follow the strategy's defined exit rules unless you square them off manually through your IIFL account.
If our platform is temporarily down, no new orders are placed during the outage. Existing positions remain at IIFL (your broker account, your positions). When the service resumes, the strategy picks up its normal execution logic. We post status updates and notify users by email and dashboard alerts.
It varies by strategy. Most strategies have a recommended minimum between ₹20,00,000 and ₹25,00,000 depending on lot sizes, margin requirements, and risk-per-trade math. Specific minimums are shown on each strategy page in the dashboard.
We charge a subscription fee per strategy, billed monthly. Brokerage, exchange fees, GST, STT, and other statutory charges are paid directly to IIFL Securities in your trading account. Please contact us for current pricing.
