Indicator of tick volumes equipped with notification system and the ability to monitor sudden and significant changes in the prices of bars relative to the specified coefficient - Change Factor - to the average value of volumes for a certain period of time (Period Signal) and the bar of the previous trading session. The color of the indicator's histogram characterizes the changes in volume of a bar: 1- relative to the previous session; 2 - relative to the signal line. According to the notification settings, the indicator reposts the percentage changes (%) on the closed bar. If several bars in a row have the same pattern of changes in volumes (color of the histogram bars does not change), notifications are not repeated for each bar. The volume of the bar and the signal line value are shown in brackets, for example (25:120): "25" - the volume of the closed bar, "120" - the value of the signal line for the period defined in the settings. If a signal is triggered for an excessive value of Change Factor relative to the signal line, then the percentage is calculated accordingly based on the value of the signal line.

Indicator Inputs

By default, the indicator bars are colored in the following colors:

• Gray - no change in volumes relative to the previous bar;
• Green - a slight increase in volume, not exceeding the Change Factor relative to the previous bar and the signal line;
• Red - a slight decrease in volume, not exceeding the Change Factor relative to the previous bar;
• Blue - significant increase in volume, exceeding the Change Factor relative to the previous bar;
• Dark blue – significant increase in volume, exceeding the Change Factor relative to the signal line;
• Yellow - significant decrease in volume, exceeding the Change Factor relative to the signal line.
