Pi Cycle Top Indicator Z-Score

This Indicator Z-scores the Pi Cycle Top Indicator by first calculating two moving averages: the 111-day moving average (111DMA) and the 350-day moving average (350DMA) of the closing price. Then, the double of the 350-day moving average (350DMAx2) is calculated.

Next, the percentage difference between the 111-day moving average and the double 350-day moving average is calculated. This difference is used to create a list of historical percentage differences.

The code calculates the mean and standard deviation of the percentage differences. Using these values, the Z-Score of the current percentage difference is calculated and inverted to generate a negative signal on a crossover.

The Z-Score is plotted as an oscillator on the chart. Additionally, dashed green lines are added at the values 1 and 2, and dashed red lines are added at the values -1 and -2.
