Question: A customer asked, “How do I make OHLC bars with\u00a0my indicator?”<\/p>\n

Answer: This can be accomplished with real time data. Your indicator needs to track Open, High and Low values with intrabarpersist variables. It also needs to track when the bars of source data streams close. That way your indicator can determine when the opening tick occurs, and when to reset the high and low variables.<\/p>\n

Here is an example EasyLanguage indicator, creating bars for (Up Volume – Down Volume) values:<\/p>\n
