Building a Trading System

A trading system is your complete framework for consistent profitability.

Components of a Trading System

1. Market Selection

• Which pairs/instruments
• Which sessions
• What conditions (trending/ranging)

2. Entry Criteria

• Setup conditions (what must be true)
• Trigger (when to enter)
• Entry type (market, limit, stop)

3. Exit Criteria

• Stop-loss placement
• Take-profit levels
• Break-even rules
• Trailing stop rules

4. Position Sizing

• Risk per trade (1-2%)
• Maximum open positions
• Correlation limits

5. Trade Management

• Partial profit rules
• When to move stops
• How to trail profits

Creating Your Edge

Your edge is what makes you profitable over time:

Example:

• 50% win rate
• Avg win: 2R
• Avg loss: 1R
• Edge = (0.5 x 2) - (0.5 x 1) = 0.5R per trade

Backtesting Your System

1. Define clear, objective rules
2. Test on historical data (min 100 trades)
3. Calculate key statistics:

- Win rate

- Profit factor

- Maximum drawdown

- Average R per trade

1. Forward test on demo
2. Go live with small size
