Why Use a Trading Simulator?

A trading simulator, commonly known as a paper trading account, allows you to build confidence and test trading strategies without risking real capital. It provides a sandboxed environment where you can experience real market mechanics.

How the Math Works

Understanding the exact formulas used in trading is crucial for managing risk and setting realistic expectations. Here's how the simulator calculates your results:

1. Gross Profit/Loss (Long Position)

Gross P/L = (Exit Price - Entry Price) × Number of Shares

For a short position, the formula flips: (Entry Price - Exit Price) × Shares

2. Total Trade Cost

Trade Cost = Entry Price × Number of Shares

This represents the capital tied up in the trade (excluding margin leverage).

3. Net Profit/Loss

Net P/L = Gross P/L - (Commission × 2)

Commissions are typically paid on both entry and exit, so the fee is multiplied by two.

4. Return on Investment (ROI)

ROI = (Net P/L ÷ Total Trade Cost) × 100

This gives you the percentage return relative to the capital risked on the trade.

Common Simulation Strategies

By treating the virtual money as if it were real and strictly following your rules, a simulator becomes the most valuable tool for transitioning into a consistently profitable trader.
