PBX Trend Signals from Stacked Exponential Moving Averages

Summary

The article defines PBX as a set of averaged exponential moving averages and uses their relative order to identify directional conditions. Its example builds three PBX lines, each averaging EMAs at progressively longer periods. It opens a long when price is above an ascending stack of lines and opens a short when price is below a descending stack. Additional rules close or reverse positions when price crosses the slower lines or the line ordering changes.

The text presents this as a way to systematize entries and exits and notes that fast crossovers can produce false signals in choppy markets. It suggests confirming signals with volume or oscillator indicators, but does not provide test results, performance measures, or parameter-selection guidance. The definition is somewhat inconsistent: it first describes a nine-period average of the MACD line, while the implementation uses averages of closing prices at multiple horizons. Readers should therefore treat the code’s actual rules as the clearest account of the proposed method.

Key ideas

• The implementation constructs three lines by averaging exponential moving averages at multiple horizons.
• Long entries require price above an ascending stack of PBX lines, while shorts require the reverse ordering.
• Price crossings and changes in line ordering provide exit or reversal conditions.
• The article warns that frequent crossings can generate false signals in volatile, sideways markets.
• It offers no empirical performance evidence, and its verbal PBX definition differs from its implementation.
