I haven't been getting these in ActTrader, mostly because the programming in my Strategies is too basic and not highly complicated, even though it is detailed.
I get these errors frequently in Excel. When I get them, I locate the point of error and do a workaround.
In ActTrader a workaround might look like:
if (History.Last(1).Close <> History.Last(2).Close) then
begin
VariableInQuestion:=History.Last(1).Close / History.Last(2).Close;
end;
if (History.Last(1).Close = History.Last(2).Close) then
begin
// Here is where you would enter some script to keep
// History.Last(1).Close from being divided by History.Last(2).Close,
// such as:
VariableInQuestion:=1;
end;
Of course, this can't be done in every area. Some places might require Delphi scripting of the ActTrader program itself.

Thanks black. Actually I'm not using any custom indicators or strategies, it seems to be tied to the alert on penetration or an out of the box moving average. Working with actfx right now and will update this post with findings.
Happy Pipping!

Definitely related to the alert on penetration. When I remove all trend lines, the error doesn't appear again. Such a great feature, hope it starts working properly soon!
Happy Pipping!

ActForex has been working on ActTrader. Have you seen all the new indicators that they have added? Some of them are terrific, like "Flipit."
I hope that they can add them to the Strategy section, and put the info for them in the manual.
So, they will probably find a way to handle your problem as well.

Yes, ActFX has done a great job of adding some new features, I like the alert on trendline penetration the best. The indicators are all nice.
Happy Pipping!
