These, along with Dynamic lists, provide a much needed new dimension, and solve some age old probs with backtesting. Thank you! You may recall that I've asked for regular Dyn Lists to be given an option to be processed just once each week, thereby allowing the limit to be lifted. But that suggestion didn't seem to fly. Here's a way of achieving the same goals with very little effort (programming or CPU), by leveraging the Historical lists feature. It would be great if you could provide a simple utility that does a *onetime* export from a formula-driven Dynamic List that automatically builds a weekly Historical List from that, and exports it for the user in the appropriate TXT format. From that point forward, the user could add symbols each new week on their own, using OT's OmniScan with their Dyn List formula, to update it with the symbols for that week. That way we could have *lots* of "efficient" historical lists that do the essential work of a dynamic list ... and we could SHARE those lists with other users (via ET?) without creating extra CPU overhead. Further benefit: Folks have been asking for an output of the Dynamic List's results ... but that could be a monstrous file if every symbol for every day since 2000. This would provide a "reasonable cross-section" (one per week) answer for that request as well. How does this idea strike you? | |
