Stan,
I am trying to filter out the last draw range of diiferences between Min and Max difference. Such ranges are almost never repeated in consecutive draws.
In History --> Sums we can find the statistics of Min and Max Differenceses, e.g. Min -53 and Max 20. If we remove such range of differences with History Sum filter (the difference in x to y levels is -53 to 20) other, smaller ranges of differences , which have no -53 and no 20, will be removed additionally: e.g. -52 to 19, -40 to 20, -30 to 18 and so on. Sometimes it could be an advantage but usually it is not.
Could you implement a Range of Diffs filter which would remove only the ranges with one or more Min difference in any levels OR one or more Max difference in any levels?
