Dr. Eric Wish's Green Line (GLB)

This indicator draws lines and corresponding labels any time a monthly all-time high (ATH) for a stock/ETF has not been penetrated for three months and has also doubled in price within the year prior to that ATH. In other words, the chart will find a high that has not been surpassed for at least three months, then look back over the past year to find the lowest low to determine if it at least doubled in order to indicate that the ATH is a valid pivot point for a Green Line Breakout (popularized by Dr. Eric Wish).

While this indicator will render on lower timeframes, it's meant to be used on the Monthly or Weekly timeframe with a Volume indicator to help determine the validity of the GLB.

In addition to independent line and label options, it includes the ability to show as few as one and up to all of the Green Lines on a chart, sorted by the most recent, as well as the option to turn off the price doubling check.
