OPEN-SOURCE SCRIPT
已更新 Bollinger bands dynamic alerts
This triple Bollinger script is very useful for options traders to determine the trend condition. When the trend stays within 1 sigma limits it is termed as "congestion", breakout of congestion starts the "trending" phase and the big breakout termed "Blowout" happens when the underlying crosses the 2sigma and reaches 3 sigma limits in very short time at steep trend angles. The script provides dynamic alerts as soon as the underlying breaks out of these zones and enables options traders to stay in the trade longer.https://www.tradingview.com/chart/s97nMr1n/
