Chandelier Exit (from the StockChart article)

"Developed by Charles Le Beau and featured in Alexander Elder's books, the Chandelier Exit sets a trailing stop-loss based on the Average True Range (ATR). The indicator is designed to keep traders in a trend and prevent an early exit as long as the trend extends. Typically, the Chandelier Exit will be above prices during a downtrend and below prices during an uptrend."

Chandelier Exit (long) = 22-day High - ATR(22) x 3
Chandelier Exit (short) = 22-day Low + ATR(22) x 3

"The Chandelier Exit formula consists of three parts: a period high or period low, the Average True Range (ATR) and a multiplier. Using the default setting of 22-periods on a daily chart, the Chandelier exit will look for the highest high or lowest low of the last 22 days. Note that there are 22 trading days in a month. This parameter (22) will also be used to calculate the Average True Range."

for renco you need a script to make an offline chart, then open the offline chart.

But to be honest it is not worth the effort.
