The Yonko Volumetric Bar type is formed by aggregating a certain amount of volume instead of using a fixed time interval or combining the interval with time if so desired. For example, our volumetric bar might be created after 1,000 contracts have been traded, regardless of how long it takes to reach that volume; or they can be utilized with time and print a new bar based on the bar period parameter. These versatile bars show their strength in choppy, ranging, and trending markets and can allow the trader to more clearly identify the beginning of a trend or trend reversal, or know when to hold/close a trade. This bar type provides the user with in-depth customization options regarding orderflow data visualization so it is recommended that the user have orderflow data available to fully benefit from their use. They are great for backtesting due to the statiscal advantage volume bars provide over time based bars.
