There's a lot of interest here in indicators that use aggregation periods. Typically, the prices used for the indicators are the open or the close for the aggregation period, but plenty of other price types exist (e.g., hl2). If I wanted to use one of these other price types for an indicator, my concern is that there could be a delay in when those price types (e.g., hl2) become available for recent aggregation periods. For example, if I'm on a 5 minute aggregation period, how quickly will the hl2 for the most recent aggregation period become available - in enough time to make real-time decisions?
