" BR_ASSET - Don't shift data series on intraday bars that end at or after AssetMarketEnd and before AssetMarketStart in the asset time zone (AssetMarketZone). This prevents updating indicators or generating trade signals outside market hours. Start and end time and zone can be individually set in the asset list. This flag must be set before calling asset.
