We discuss:

• Python is a great general-purpose language, but that's what makes it a bad choice for backtesting
• Iterating on your strategies is the critical piece - anything that makes that more complex will make things more difficult
• In a world of LLMs, the argument for using Python for everything makes less sense
• Choose your tools based on profit potential, not because "I like Python and am good at it."

Dave continues helping Michael create a first backtest in Amibroker. You might think "backtesting is backtesting," but we cover many of the differences between RealTest and Amibroker, as well as their implications.

We discuss:

• What makes AI so bad at generating good AFL code for a backtest in Amibroker
• The better you get at understanding how AFL works, the better your use of AI gets
• How a column library makes all the difference in creating P&L
• Quick backtests can promote bad habits

And much more...

Dave also announces the new MabeKit AFL Generator tool.

Dave offers advice and feedback to Michael, who is learning to use Amibroker for the first time.

He's coming from RealTest, so we go over the similarities and differences between the two platforms.

We discuss:

• How RealTest is great for daily data, but hits a wall for most intraday trading strategies
• Amibroker is not just a backtester; it’s a full charting, analysis, and execution environment.
• Backfilling with IQFeed versus Polygon (there is really no contest)
• Best practices for databases in Amibroker

As traders gain experience, the problem shifts from not having enough ideas to having too many ideas competing for limited time and mental energy. Without a system, this abundance quickly becomes overwhelming and leads to paralysis or procrastination.

We discuss the ICE method - a simple scoring method to determine which ideas to work on first.

In this week's episode of Line Your Own Pockets, we take on a topic submitted by Isaac, a trader I work with.

We discuss:

• When timing/speed matters and when it doesn't
• The types of trading strategies where latency is likely the bottleneck
• How rushing to solve problems can be counter-productive (waiting can reveal simpler solutions)
• Concrete steps to determine if latency is really an issue and how to address it

We butt heads in this episode, arguing about the value of portfolio-level backtesting, one of the key feature differences between RealTest and Amibroker.

Is portfolio-level testing essential, or simply premature optimization?

We discuss:

• How to optimize so you have to re-optimize as little as possible
• How better columns directly translate into more robust strategies
• Hold a rule "in reserve" so you can apply it when needed without full re-optimization
• Documenting previous optimization decisions will make the next strategy better
• And much more...
