I used to manually draw lines to indicate impact zoones of sessions aand so i made this indicator to automatically ark up session lines at impact zones
which helps in visualizing historical data per day when viewd in TF like 5mins. also tells you live as a session lapses.
this works fully on IDC and Pepperstone charts it might not visualize Asian session for some brokers due to their price compiling standards: like using different day breaks etc.
i marked the sessions as following : colors ASIAN : YELLOW EURO : BLUE US : Red /pink
