The Wadda Attar Explosion has been around a long time. It's actually an amazing system now that I have looked at it on Tradingview and read the rules that LazyBear provided (for some reason I never traded this indicator). Thanks to Lazy Bear he has immortalized this system for TradingView with clear rules and timeframe to use.


New version 2, also working in crypto
