I have a custom ACSIL study built as an external DLL using Visual Studio. I am calling ReadIntradayFileRecordForBarIndexAndSubIndex but it always returns 0 regardless of settings. My diagnostics show: FileRecordIndexOfLastDataRecordInChart = 19307381 (file exists and has records) ArraySize = 1438 ChartDataType = 2 (intraday) IntradayDataStorageTimeUnit = 0 (this seems wrong) Intraday Data Storage Time Unit in Global Settings = 1 Tick Sierra Chart version 2888, revision 55876 Data feed: Rithmic via DTC Symbol: ESM6.CME (non-continuous) The scid file exists at C:\SierraChart\Data\ESM6.CME.scid and is 736MB. Questions: Why does IntradayDataStorageTimeUnit report 0 when Global Settings shows 1 Tick? Is there anything required in SetDefaults to enable intraday file record access for an external DLL? Is ReadIntradayFileRecordForBarIndexAndSubIndex supported for externally compiled DLLs with Rithmic/DTC feeds?
