Have you ever heard of a stop placement strategy that trails stop based on previous ‘high’ points? It is called Chandelier exit as it hangs down from the high point or the ceiling of our trade, just as a chandelier hangs from a room ceiling. The distance, which is usually calculated from the high point to the trailing stop; could also be calculated in dollars or in contract based points. However, the value of this trailing stop moves upward very promptly as higher highs is reached.
The Chandelier Exit, which has a trailing stop from either the highest high of the trade or the highest close of the trade, is best measured in units of Average True Range (ATR). One of the many factors leading to use ATR for measuring the distance from the high to our stop is that, it is pertinent across markets and is adaptive to changes in unpredictability.
