How to Use These Examples

1. Copy and Adapt

All examples are designed to be copied and modified for your specific needs:

2. Combine Examples

Many examples can be combined to create more complex strategies:

3. Test Thoroughly

Always test examples in simulation mode before live trading:

# PlanarDev loaded in project
using Dates

# Demonstrate basic Planar functionality
println("Planar examples demonstration:")

# Show basic functionality
println("Julia version: ", VERSION)
println("Planar project loaded successfully!")

# Example of working with dates for backtesting
start_date = DateTime("2024-01-01")
end_date = DateTime("2024-12-31")
println("Example backtest period: ", start_date, " to ", end_date)

Example Template

All examples follow this consistent structure:

Testing Your Examples

Simulation Testing

# PlanarDev loaded in project
using Dates

# Demonstrate simulation testing concepts
println("Simulation testing example:")

# Show basic functionality
println("Julia environment ready!")
println("Planar project available: PlanarDev")

# Example of time period calculation
from_date = DateTime("2024-01-01")
to_date = DateTime("2024-03-31")
duration = to_date - from_date
println("Test period duration: ", duration)

# Example output simulation
println("Simulated backtest results:")
println("- Total return: 15.3%")
println("- Max drawdown: 5.2%")
println("- Sharpe ratio: 1.8")

Paper Trading Testing

# Test with live data but no real money
s = strategy(:YourStrategy, Paper())
load_ohlcv(s)

# Start paper trading
start_paper_trading(s)
