PRELOAD
Use Zorro's historical price data, rather than loading price data from the broker's price server or from external data sources. For filling the LookBack period at [Trade] start, the data span between the end of the history and the current time is loaded from the broker or data source. This flag is useful for reducing the trading start time of a system, for overcoming history limitations of broker servers, or for extremely long lookback periods. Recent price history files from the current and the last year must be available; use the Download script for getting the most recent data. Setting this flag also suppresses the warning message in [Test] mode when the lookback period is too long for a normal trading session.
