If one builds a PCF looking for a particular set of circumstances, what procedures are used to back test the idea?

TeleChart was not really built for backtesting. However, you can use the days ago parameter with your PCF's to look for conditions met at some point in the past.

For instance, if you wanted to find stocks where price crossed above a particular moving average, say 3 months ago, so you could find out how the stock price has behaved since, you could do something like this:

(C63 < AVGC50.63) AND (C62 > AVGC50.62)

Your can even do the same type of thing using dates like this:

(C'09/30/04' < AVGC50'09/30/04') AND (C'10/01/04' > AVGC50'10/01/04')

Thanks, I thought that there might an easy way to back test an idea without setting arbitrary time constraints.

This video explains an easy way to back test an idea when you don't know the exact timeframe:

IMHO, the easiest way to backtest a PCF is to make a custom indicator out of it and plot it. Modify the PCF as required to create "true/false" results to indicate your entry/exit signals, and plot it as a Custom Percent True (no smoothing). The "spikes" that appear are very easy to see. Set the Zoom to about 4, and start spacebarring thru the WL. For many reasons, I often find this approach to be more helpful than formal backtesting mechanisms, particularly during early development of a new idea.

That is the method taught in my video that Bruce linked to above.

So right ... and a very good explanation it is ... my apologies for not reviewing the video first!

I used to use Stockfinder and there was backtesting available.  When I rejoined, Stockfinder was discontinued so I joined tc2000, but I could really use the backtesting feature to fine tune a test/tweak my trading.

Is there any plans on ever adding that backtesting feature to tc2000?

I do not know when or if backtesting features might be added to TC2000.

StockFinder is still available, but is no longer in development and will not get new features or bug fixes.
