Hello I have indicator to plot gann angle and predict the high and low price i need to add the below requirement on the indicator and remove some specification from the indicator: 1- plot daily,weekly,monthly,yearly angle level based on the formula I will shear with you. 2-Plot horizontal level based on calculation I will shear with you. 3-the indicator will plot his own chart I do not need that I need to remove it. 4-alert if the indicator touch the horizontal level. 6-add vertical line between each day,month,week,year. 7-the indicator will plot the angle level and horizontal level starting from the past years to the current day. 8- show and hide option required for the period and the levels. 9-the angle level should not change if the chart zoom-in and zoom-out or the time frame changed. Thank you
