Trade strategies

Ive been messing around with trade strategies on individual corporations and it doesnt seem to have any affect. Has this feature been nerfed?

The feature is unchanged and it works.

this does not mean that all changes in strategies will have an effect.

Keep tuning and check what it does.

Oops. I see that this one is very old.

It's funny this is near the top of the forum, because it's something I've been looking into the last couple of days.
Starting from a fresh corporation, I tried increasing the quality tracking sell percent to 140%. The sale strategy then says it sells for 140% instead of 120%, but checking the recent sales I still only see a sale for 120% over 100 quality. I waited a couple months to verify.
Then I tried using time based quality - thinking that since this is a brand new corporation, and 120 seems like a capped minimum, maybe it was like quality 80 or 90 in the backend. I set the time based to 160% and nothing happened the next month either, just another regular sale for 120% over quality 100.
Then I tried quality based again and set it to 250%. Same thing, no change.
