I'd like a scan that provides this:

stock that doubled in the past year

trades near its all time high

and the rest I can do. (I think)

Also,  is it possible to place an alert on an entire watchlist. 

Many thanks,

Beth

It is not possible to place an alert on entire WatchList. There is a limit of 100 simultaneous Alerts in Gold and 200 simultaneous Alerts in Platinum. Scanning WatchLists is done with EasyScans.

A Condition Formula for price doubling in the last year is relatively simple.

C >= 2 * C252

The above would work in a Daily Time Frame because 252-Trading Days is a relatively good approximation of the length of a year.

Trading near an all time high is not possible to create as a Condition Formula however. For one thing, there are only 500-bars of data available in any given Time Frame in TC2000 version 12.2. For another, it is not possible to create a formula which determines the number of bars available and then only uses that many bars in its calculation. If any part of a formula requires 500 bars of data, then the formula would not calculate at all for any symbols with less than 500 bars of data available.

You might want to check out the All Time Highs topic if you are willing to use TC2000 version 7 for this instead.

It would be possible to do this in StockFinder.

new high
Within 25% of all time high

You could then copy and paste the symbols returned from StockFinder into TC2000 version 12.2.
