Hello,
Is it possible to import Telechart data to cut off at a certain PAST date? If I for example would like to get rid of all data after March 10 2009. Or whatever date. Is there a trick I can apply?
Many thanks,
Regards.

Welcome to the forums. A very good foundation for learning how to use TeleChart can be gained by reviewing the following:
If you are new to TeleChart READ THIS FIRST!
Clipping your chart back to a previous date is possible, but that will not actually limit the data itself. Any Personal Criteria Formulas, Sorts and EasyScans will still work as if all of the data is there.
If the idea is to backtest, TeleChart does not have any built in backtesting features. It is possible to visually backtest the technical (but not fundamental) portions of a scan (but this would not give you a count):
Visually Backtesting Specific Symbols
It is also possible to write Personal Criteria Formulas based on past dates (again, this is only for technicals) for use as EasyScan Conditions. You may wist to review the following section of the Online Help Files:
Days Ago parameter
There are two distinct ways to use historical data with Personal Criteria Formulas.
Any criteria can be used to scan X number of days back by adding '.XX' where XX is equal to the number of market days past to calculate for. An example of this is (AVGC21.21), which is a 21 day moving average 21 of close, 21 days ago. This use of historical data always refers to the market day XX number of days ago (in this case, 21). If you wish to use a specific date’s data, use the option detailed below.
The other method of using historical data is by specifying a precise date in history to use. For example, (AVGC21.'11/13/08') will provide a 21 day moving average of close for November 13, 2008 (the period should be used in cases where the first method requires a period and not used when the first method does not use a period). Always confirm that the date you wish to use using this parameter was a market day.

OK, thanks for the info. That's OK, I already read something about the limitation of backtesting. The visual 'backtest' is pretty useful many times for me, but ... however... there is no way? Could I save e.g. today the Telechart database in another folder on my pc and so I would have later at least 1 older Telechart database? If I would this daily I would build a Telechart daily 'old' database? Or no way Jose this would work?
Many thanks for the help, I'll be around the forum quite more than before I expect.

I can't think of a way.
