![]() ![]() ![]() In Automatic Analyzer (AA) operations, data Alignment can be turned On/Off and the Reference Symbol to be used for alignment can be specified. The process of fixing and padding data to allow these operations is called data alignment. Such operations would include several AA functions, the creation of composites, and chart overlays. While AmiBroker never modifies the data it collects and stores in your database, it may fill in and fix holes during operations that require a common time base. However, as will be explained below, this is not the case when plotting foreign data. Because of this you cannot visually detect any holes. When plotting Indicators based on the selected current symbol, holes are skipped to create continuous looking charts. When this happens, the database is updated. Holes may be filled in during backfill or when the data provider transmits data corrections. The database record simply skips to the next bar-period. When a bar has no data, the bar is not added to the database. They can last for any length of time and can occur in any timeframe. Holes can occur when a ticker isn?t trading or when the data feed is interrupted. When AmiBroker doesn?t receive data during regular trading hours, the missing period or bar is referred to as a Hole in the data array. ![]()
