Hey - it's probably not going to be that simple. Let's say you buy 2.151762 shares of KO in one trade. So in Monera, you have one line. But the Ti time test only runs on those 2 whole stocks. When there is a date in that line, there must be info there too, but that test runs not on the entire purchase, but only on 2 shares. (And maybe even for the whole purchase, if you supplemented the fractional purchases from the past with that fraction.)

in a year you buy 3.91142 shares of KO. So Ti on 4 shares starts to run the time test (because sum of rakish buys). Therefore, it would not only be enough to add a column with the date of the end of the test, but also the number of shares involved. And as part of the recalculation, constantly recalculate due to fractional shares and backfill to N lines. Let's say you buy DCA for $100 per day Nasdaq = all lines will have an empty time-trial date until you get to one piece and then have to backfill all those existing purchases.

That's pretty complicated for programming. I can imagine it for whole stocks, but fractional buying complicates it quite a bit. It's not unrealistic, but it's going to be pretty expensive to develop.
