What is Day Trading?
Day trading is a trading style where financial instruments (stocks, options, futures, or currencies) are bought and sold within the same trading day. Day traders aim to profit from short-term price movements, closing all positions before the market closes to avoid overnight risk.
Real day trading involves market and execution risk. This fixed-price exercise teaches account arithmetic, but omits the changing prices and costs that determine real outcomes.
Why Practice with a Trading Simulator?
- Zero Financial Risk - Learn trading mechanics without risking your hard-earned money.
- Check Cash Usage - Compare an order value with available virtual cash and observe the resulting share count.
- Check Limit Conditions - Compare an unfilled buy limit below the quote with a marketable limit at or above it.
- Learn from Mistakes - Make errors in a safe environment and understand the consequences without real losses.
- Understand the Boundary - Fixed examples cannot reproduce volatility, order priority, or a live trading record.
Key Trading Concepts to Master
Market Orders vs. Limit Orders
Market Orders seek prompt execution at available prices. The last traded quote is not a guaranteed fill; liquidity and trading halts can affect execution. This simplified exercise always uses its fixed example price.
Limit Orders set a maximum buy price or minimum sell price. Real fills can occur at that price or better but are not guaranteed. Here a marketable limit fills at the displayed example quote; other limits return unfilled without remaining pending.
Position Sizing
Position sizing is determining how many shares to buy or sell based on the planned exposure and loss budget. Buying power is not a loss limit. This tool checks whole shares and available cash only; it does not implement stops, margin rules, or an account-risk recommendation.
Profit & Loss (P&L)
Unrealized P&L is the profit or loss on open positions that haven't been closed yet. It fluctuates with market prices.
Realized P&L is the difference between sale proceeds and the cost basis of closed shares, after relevant costs. In this fixed-price, no-cost model, realized and unrealized P&L remain zero; the displayed dollars are virtual.
Frequently Asked Questions
Do I need an account?
No account is needed for this public exercise. It saves the virtual account in this browser when local storage is available. It is not synced across devices or connected to a brokerage.
Are these live prices or historical replay?
Neither. The six stock labels use fixed illustrative prices with no market feed or price changes. They are not current quotes or split-adjusted historical observations. With unchanged prices and no costs, valid round trips produce zero P&L.
How are limit orders handled?
A buy limit fills only when it is at least the fixed quote; a sell limit fills only when it is at most the fixed quote. Both fill at that quote, not at an arbitrary entered limit. Otherwise the order is not filled and is not kept pending. This simplification omits queues, spreads, partial fills, and slippage.
Can I trade crypto, short stocks, or test a strategy?
No. This version supports whole-share, long-only trades in six stock examples. It has no charts, changing prices, short sales, margin, fees, taxes, session rules, or strategy backtest. Use it to understand cash and holdings, not to estimate trading skill or returns.
What happens when I close the browser?
A valid saved account is restored on the same browser and origin, subject to storage availability. The most recent 100 trades are kept, with 10 displayed. Clearing site data removes this exercise. Earlier simulator records use a different model and are not imported into this corrected version.
Order definitions and limits
