Import Specification
Description
Price data adjustment setting
Syntax
Adjustment: choice
Choices
TotalReturn - all types of dividends are converted to splits
CapitalSpecial - corporate restructure events (mergers etc.) and special dividends are converted to splits
Capital - (default) no dividend types are converted to splits
None - adjustment information is not imported (not recommended)
Notes
RealTest receives adjusted and unadjusted prices along with split and dividend histories from Norgate and some other sources.
Imported data is then stored and used in unadjusted form so that each price reference on a given date reflects the actual price that was traded on that date.
When necessary for multi-bar indicator calculation or lookback comparisons, on-the-fly adjustment is performed.
See Split Handling for additional details about how this works.
General best practice is to use the default Capital in most cases.
Here are the trade-offs for each choice:
•TotalReturn converts all dividends to splits. This makes trades held across an ex-dividend date look like their share quantities were adjusted when they actually would not have been.
•CapitalSpecial does the above for special dividends including corporate restructuring events while correctly simulating payout of ordinary dividends.
•Capital only treats actual stock splits as splits while simulating payout as a dividend of every other adjustment event. This introduces an occasional large price gap (with corresponding simulated dividend payout) around corporate restructuring events.
Adjustment can optionally be specified separately for each DataSource block in an import definition. This enables your data to include a mix of e.g. TotalReturn and Capital-only adjusted symbols. It is even possible to import the same symbol from the same source both ways by defining two DataSource blocks for the same source and using the IncludeList alias syntax for one of the instances of the symbol.
