Paper Trading Guide

Practice trading strategies with simulated money before risking real capital. Paper trading lets you test strategies in real market conditions without financial risk.

Paper trading uses real market data but simulated money. Orders execute at real prices, giving you realistic practice for live trading.

What is Paper Trading?

Paper trading is simulated trading with virtual money that mimics real market conditions. It bridges the gap between backtesting and live trading.

Backtesting

Tests strategies on historical data. Fast but uses past prices.

✓ Instant results
✗ Not real-time

Paper Trading

Simulated trading with current market prices. Real-time practice.

✓ Real-time data
✓ No risk
✓ Practice execution

Live Trading

Real money, real risk. Only after proven strategy.

✓ Real profits
✗ Real losses

Getting Started with Paper Trading

Create a Paper Portfolio

  1. Navigate to Paper Trading in the sidebar
  2. Click "Create New Portfolio"
  3. Configure your portfolio:

    Portfolio Name

    Descriptive name (e.g., "Momentum Strategy Live Test")

    Starting Capital

    How much virtual money to start with (e.g., $100,000)

    Risk Rules

    Max position size, max portfolio loss, max positions

  4. Click "Create Portfolio"

Tip: Create multiple portfolios to test different strategies simultaneously. For example, one for momentum trades and another for mean reversion.

Placing Orders

Stratify supports all standard order types used in live trading:

Market Order

Buys or sells immediately at current market price. Guaranteed execution but price varies.

Example:

"Buy 100 shares of AAPL at market" → Executes instantly at current ask price (~$180.50)

Use when: You want immediate entry/exit and price is acceptable

🎯

Limit Order

Buys or sells only at specified price or better. May not execute if price doesn't reach limit.

Example:

"Buy 100 AAPL with limit $178" → Only executes if price drops to $178 or below
"Sell 100 AAPL with limit $185" → Only executes if price rises to $185 or above

Use when: You want to control entry/exit price and can wait

🛑

Stop Order (Stop Loss)

Becomes a market order when price hits the stop level. Used to limit losses or protect profits.

Example:

You own 100 AAPL at $180. Set stop at $176 → If price drops to $176, sells at market (~$175.90)

Use when: You want automatic exit below/above a certain price

⚙️

Stop-Limit Order

Combines stop and limit. When stop is hit, places a limit order. More control but may not execute.

Example:

Stop: $176, Limit: $175 → If price drops to $176, places limit order to sell at $175 or better
(Protects against executing far below stop in fast-moving markets)

Use when: You want stop loss but also price protection

How to Place an Order

  1. In Paper Trading view, click "New Order"
  2. Search for the symbol you want to trade
  3. Choose Buy or Sell
  4. Select order type (Market, Limit, Stop, Stop-Limit)

Paper Trading Best Practices

💡 Treat It Like Real Money

Follow your risk rules, use realistic position sizes, and don't take trades you wouldn't take with real money.

💡 Journal Every Trade

Record why you entered, your plan, emotions, and lessons learned. The journal is more valuable than the P&L.

💡 Test All Order Types

Practice with market, limit, stop, and stop-limit orders. Understand how each works before using live.

💡 Track Key Metrics

Focus on win rate, profit factor, max drawdown, and average win/loss ratio - not just total return.

💡 Be Patient

Paper trade for several months through different market conditions before going live. Impatience causes most failures.
