The History Movement Changes statistic tracks consecutive sum and difference increases and decreases on each level ...++ or two --, the filter statistic is set to remove the levels that break the trend. ie ++- and --+.
This feature has only been available a few weeks, but I find that running say 10 sets of what if numbers will provide you with a very good pointer as to firstly what levels will increase or decrease (two uses so far and both times have produced 100% accurate results, particularly for differences, sums not so accurate) and then you can use that information to predict which levels might continue to be + or - or those that won't and then filter in the movement changes statistics accordingly. If you can give this a narrow setting..one or two levels maximum range you should find you can remove a lot of combinations.
Also as a general rule, it is rare for there to be a 100% continuation of consecutive + or - or for that matter pos and neg differences - the maximum range is more like 80/20. However filtering like that, although safe, will not remove many tickets.
