Dual Moving Average Crossover Trading Strategy
• Definitions:– STMA Short term moving average– LTMA Long term moving average
• Economic Rationale & Strategy– Technical Momentum-based approach– Value “Mean-reversion” approach

Data
• High frequency foreign exchange data– Currency rate: EUR:USD
– 5 minute intervals
– January 03, 1999 to February 06, 2002
– 328K + observations
– Removed “stale” weekend data
• Hold out Sample – Approximately 37 weeks of data (75,000 observations)
![Page 5: Captain Carnage Asset Management: Dual Moving Average Crossover (DMAC) Trading Strategy Merrill Liechty Murray Spence Lance Stover](https://reader036.vdocument.in/reader036/viewer/2022082517/56649f355503460f94c5302c/html5/thumbnails/5.jpg)
Methodology
– Calculate crossover points– Determine Buy /Sell trading signals– Calculate metrics for each pair of moving
averages:• Profit (with and without slippage)• # Wins / # Losses• Average Win / Loss• Max/Min Portfolio Value• % Time Below Initial Investment

Software
• Challenges– Data set too large for Excel 64,000 row limit
– Needed stronger computational power to consider nearly 5000 DMAC combinations
• Selected C++ as development platform– Considered all combinations of 10 unit SMA intervals up
to 1000 (e.g. 10,50; 220,740)

Parameter Selection for Out of Sample Analysis
We did not select the best performing MA pair of 5000 candidates to go out-of-sample!

Conclusions
– In Sample• DMAC provides consistent profits when slippage is
not considered.• Slippage makes a “blind” DMAC strategy
unprofitable.• Technical approach outperforms value approach.
– Out of Sample• Selecting “intelligent” DMAC parameters yields
small but consistent profits with low risk.

Potential Issues
• Data– Quality of data– Need to examine multiple currencies
• Methodology– Parameter selection and “over-optimization”
• Risks– More than standard deviation– Consider “filter approach” to reduce whipsaws

Next Steps
• Capture more profit through better timing strategies – Identify “trending” versus trading periods– Consider hidden Markov statistical modeling
• Selection of asset classes (currencies, securities, futures)
• Catastrophic event analysis
