This strategy calculates percentage price difference between multiple EMA pairs to determine trend direction, and trades based on the Vegas wave.

Specifically, it computes percentage price differences between current price, 144-period EMA, 169-period EMA and 233-period EMA. Long signals are generated when all three meet the preset positive difference threshold. Shorts are triggered when price falls below all three EMAs and 144-period EMA crosses below 233-period EMA.

The EMA combo filters more false breaks compared to single EMA. Also, the Vegas wave itself contains multiple EMAs for robust trend analysis.

However, EMAs have inherent lag and cannot identify optimal entries. And there is subjectivity in wave theory, with performance relying largely on parameter optimization. Prudent assessment of live results is required.

Overall, the Vegas trend wave strategy synergizes EMA analysis and wave theory for good results in trending markets. But risk management remains crucial for long-term application.
