This is a very simple indicator that will highlight the background vertically over every Monday for Futures, Forex and CFD markets. I use this indicator in all my technical analysis as it lets me very quickly see where each week begins without being too distracting. It can be easily customizable to whatever color, transparency level and visibility you want. Because of the way closing times are processed in different markets I could not make a single indicator to include all markets, but check out my second Monday Highlight indicator for Crypto and Stock markets.
Hope you find them useful and don't forget to add them to your "favorites" list for easy access.
