/*********************************************************************************************** Title: POC/Value Area (Lookback) Indicator for eSignal By: Divergence Software, Inc. Web: http://www.sr-analyst.com ================================================================================================ Project Description: This indicator calculates the POC (Point of Control) as well as the Value Area on intraday charts based on a specific lookback period (in minutes) that you input. You can select to calculate the POC and Value Area based on volume (i.e., Volume Profile) or based on price (i.e., similar to Market Profile). Note that this indicator operates on intraday charts only (i.e., 1-min and up). Indicator Parameters: ==================== Calculation Options: Lookback: Specify the lookback period, in minutes. Default value is 120 minutes, which equates to 2 hours. Lookback Type: Select from "Bar Time" and "Calendar Time". If "Bar Time" is selected then the lookback period will ignore weekends or gaps in overnight trading. So whatever amount of time you have specified in Lookback, it will accumulate that many bars worth of data. If "Calendar Time" is selected then it will base the lookback strictly on calendar time. So if it is 10:30 in the morning and you have specified a 4-hour lookback, if the security you are charting started trading at 9:30 and had no overnight trading, then the POC will be based only from 9:30 to 10:30. Calculation Type: Select from "TPO on Volume" and "TPO on Price". When "TPO on Volume" is selected, the total volume traded at each price increment is used to calculate the POC and Value Area. When "TPO on Price" is selected then price only is used to calculate the POC and Value Area. The default is "TPO on Volume". Tick/Pip Size: Specify the tick/pip size of the instrument you are charting. This is an extremely important parameter so make sure you have specified the correct value. The default is 0.25 which is suitable for the eMini. Value Area Percentage: Specify the percentage to use for the Value Area calculation. The default value is 70 percent. Enter a value between 1 and 100. Cosmetic Options: Display POC?: True or False. Default is true. When set to false the POC line will not be displayed.
