Order Blocks Volume indicator

Estimado Iván, gracias por publicar estos indicadores, ¡gran trabajo! Dos indicadores que realmente echo de menos de TradingView son: Chandelier Exit de Alex Orekhov y Nadaraya-Watson Envelope de LuxAlgo. Incluyo los códigos por si te gustaría programarlos en PRT, ¡gracias!
