Ask PortoAI anything...

You want to buy 50 shares of RELIANCE. It feels like a solid add. But you already own RELIANCE. And you own ONGC and BPCL too. Your energy sector exposure is already at 24%.

Will this trade push any single stock above 20%? Will your sector concentration cross the 40% warning line? Will your margin utilization jump to a risky level?

You don't know. Because you can't see the after picture until after you've placed the trade.

What if you could see the consequences of a trade. Before you commit a single rupee?

What changes

Every dimension of portfolio impact

Concentration change

See how the trade shifts your single-stock weight, top-3 concentration, and HHI (diversification index). "Adding 50 shares of RELIANCE takes it from 15% to 22% of your portfolio."

Sector shift

Will this trade overweight banking? Add more IT exposure? See sector allocation before and after.

New risk flags

Crosses the 20% single-stock threshold? Sector goes above 40%? The simulator flags risks that didn't exist before the trade.

Margin impact

How does this trade affect your available margin? Will it push margin utilization into the warning zone?

“Spent two hours researching a stock last month. Asked PortoAI about Tata Motors this week, filings, peer comparison, risk flags, portfolio fit, all in under two minutes. Saved me roughly 6 hours of research this month alone.”

“Portfolio was deep red, I was about to double down on a losing Bank Nifty position. Got a revenge trade warning. Closed the app, went for a walk. That position dropped another 8% over the next week. PortoAI saved me roughly ₹12,400 on that single trade.”

“Used to keep Screener, TradingView, and Zerodha Kite open in three tabs. Now I just ask PortoAI. Fundamentals, technicals, risk check, position size. Cut my pre-trade research from 20 minutes to 3 minutes per stock.”

Trade simulator FAQ

Real-time data, metrics, orders, and simulation scope.

Is the simulation based on real-time data?

Yes. It uses your current portfolio holdings and live market prices to calculate the before/after snapshot.

What metrics change in the simulation?

Single-stock weight, top-3 concentration, HHI (Herfindahl-Hirschman Index), sector allocation, risk flag count, and margin utilization.

Does simulating a trade actually place an order?

No. The simulator only shows what would change. No orders are placed. If you want to proceed with the trade after seeing the impact, you can ask PortoAI to place the order separately.

Can I simulate both buys and sells?

Yes. Simulate adding a new position, increasing an existing one, partial sells, or complete exits. Each shows the portfolio impact.

What does the trade impact simulator show before I place an order?

It shows how the trade changes your portfolio weight in that stock, sector, and asset class. It also shows the change in your overall portfolio risk profile and whether the trade creates a new concentration.

Can I simulate selling a position?

Yes. You can simulate both buys and sells. The simulator shows how a sale changes your cash allocation, tax implications (short-term vs long-term capital gains), and remaining exposure.

Does it work for options trades?

Yes. For options, the simulator shows how the position changes your net delta, premium outflow, and maximum risk scenario alongside your existing portfolio.

Is this connected to my actual Zerodha account?

Yes. When you connect Zerodha, the simulator uses your real holdings as the baseline. Every simulated trade is calculated against your actual current portfolio, not a hypothetical one.
