AmiBroker.Data.QuotationList.Merge() method collects and builds intraday quotes of proper periodicity. E.g. 5 min bar data can be built by passing in RT tick data as they arrive in the data stream. If an intraday quote is passed in, it is either added as the last intraday quote (added to the end of the quote list or inserted before the EOD quote if EOD exists) or merged into the last intraday quote based on the time of the quote and periodicity of the list. If an EOD quote is passed in, it is inserted ot if the EOD quote already exists, it is updated. Intraday quotes must be passed in in their order. EOD quotes can be passed in any order.
AmiBroker.Data.QuotationList.MergeEod() method collects and builds EOD quotes. Intraday quote is merged into the EOD quote for the trading date. EOD quote is inserted or if the EOD quote already exists, it is updated. Intraday quotes must be passed in in their order. EOD quotes can be passed in in any order.
