Bars Back

The pivot calculations for a large file could take considerable time. For example, performing a run test with history AddHistSignals1 does the following for each stock: It looks at the stock with only the first 60 bars, and tests if a signal was made. It then adds one bar, and tests again. If there are, say, 5000 bars, the test will be very long. You may want to view only the last 100 bars.

Set the number of  Bars Back o a non-zero value. Then set the Start Date to any date. StartDate1. For files other than csi files, the only meaning is whether it is null, '//', or an actual date. If it is null, then the entire file will be read. For csi files, it goes back to the date specified in the Start Date and counts bars back. For other files, it counts bars back. The file, as viewed in the chart and for run tests, will then have only the small number of bars back.

If you wish to view the entire file, set Bars Back to 0.

To repeat, Start Date is relevant only for csi files.
