Cette stratégie permet de juger de l’évolution du marché en calculant la croisée des indicateurs de dynamique et des indicateurs de panique, et d’émettre un signal de vente lorsque les deux indicateurs se croisent de manière spécifique, afin de capturer une tendance à la baisse.
Cette stratégie lance des avertissements de baisse de marché par le croisement d’indicateurs de dynamique et d’indicateurs de panique. Elle peut capturer efficacement les baisses soudaines du marché. Cependant, la stratégie ne convient qu’aux applications de courte durée, sans mécanisme d’exit et de contrôle du risque.

//THIS SCRIPT HAS BEEN BUIL TO BE USED AS A S&P500 SPY CRASH INDICATOR (should not be used as a strategy).
//THIS SCRIPT HAS BEEN BUILT AS A STRATEGY FOR VISUALIZATION PURPOSES ONLY AND HAS NOT BEEN OPTIMISED FOR PROFIT.
//The script has been built to show as a lower indicator and also gives visual SELL signal on top when conditions are met. BARE IN MIND NO STOP LOSS, NOR ADVANCED EXIT STRATEGY HAS BEEN BUILT.
//As well as the chart SELL signal an alert has also been built into this script.
//The script utilizes a VIX indicator (marron line) and 50 period Momentum (blue line) and Danger/No trade zone(pink shading).
//When the Momentum line crosses down across the VIX this is a sell off but in order to only signal major sell offs the SELL signal only triggers if the momentum continues down through the danger zone.
//To use this indicator to identify ideal buying then you should only buy when Momentum line is crossed above the VIX and the Momentum line is above the Danger Zone.
//This is best used as a daily time frame indicator
