Stock market simulator for India: how it works

What is a stock market simulator?

A stock market simulator is software that lets you trade without real money. It shows you market prices and accepts your orders. Then it decides when each order fills, tracks your open positions and keeps your P&L.

A good simulator feels like a real trading app. The screens, order types and exits should match what you will use later. Otherwise you practise the wrong habits.

How does a stock market simulator work?

Every simulator does four jobs.

1. Show prices. It follows market prices for the instruments it covers.
2. Take orders. You choose buy or sell, quantity, order type and product type.
3. Fill orders. It checks each order against the price and fills it when the rules say so.
4. Keep records. It updates your virtual money, positions, holdings and P&L.

In ZeroStake, a market order fills in full at the last price the app has, by default. A limit order waits until the price reaches your level. A stop-loss works like a stop-loss market (SL-M) order: when the price touches the trigger, the exit fills at the next price. That price can be at, above or below your trigger, as it can be with a broker.

Today’s market or a past session?

ZeroStake gives you two kinds of practice. Each one trains something different.

Use both. Trade today’s market to learn patience. Use replay to see more setups in a week than the calendar shows you in a month.

What does ZeroStake cover?

ZeroStake covers the full path of a trade. Some tools need ZeroStake Pro, an optional plan in the app.

• Instruments: NSE and BSE stocks, indices, futures and options, plus MCX futures and options.
• Orders: market, limit, stop-loss, target, AMO and GTT orders.
• Products: intraday, delivery and F&O.
• Exits: stop-loss and target handles you drag on the chart, and a trailing stop-loss.
• Fills: in full at the last price by default, or harder with LiveFill on Easy, Medium or Hard.
• Options: an Option Chain for 5 indices and 6 MCX commodities. A Strategy Builder for any underlying with listed options.
• Costs: estimated brokerage, taxes and other charges on every trade.
• Review: gross and net P&L, win rate, profit factor, expectancy, drawdown, streaks and a Trade Journal.

What can a simulator not copy?

No simulator copies a real exchange exactly. These are the main gaps.

• Queue position. On an exchange, your limit order waits behind others at the same price. In a simulator, it fills when the price reaches it.
• Partial fills. A large real order may fill in parts. In ZeroStake, an order fills in full by default. Turn on LiveFill to practise with partial fills.
• Slippage in fast markets. Real prices can jump past your stop. A ZeroStake stop fills at the next price it sees. With LiveFill on, any order can also fill at a worse price.
• Your emotions. Fear and greed are stronger when the money is real.

Read the full list on the methodology page. Knowing the gaps keeps your expectations honest.

How do you choose a stock market simulator?

Check four things before you commit time to any simulator.

1. It covers the instruments you plan to trade, including F&O if you trade options.
2. It has the same order and exit types as your future broker.
3. It counts charges, so your net P&L means something.
4. It gives you a review tool, so practice turns into learning.

ZeroStake meets all four for Indian markets. It runs on Android, iPhone and iPad.
