The end result for illiquid markets produces something like:
Selection # | LTP | Favouritism Rank
1. | Null | 3
2. | 2.88 | 4
3. | 3.05 | 5
4. | Null | 2
5. | 6.6 | 7
6. | Null | 1
7. | 6.0 | 6
The obvious suggestion is to put anything which hasn't traded any volume to the back of the rankings.
As such I've had trouble using the Fix the Order of the Market Selections rule on various markets and I don't see how it's viable to be using 'order by favouritism' until you've checked every selection has traded vol > 0 which requires 1 rule per potential selection so we're talking 40+ rules per automation file to account for large field sizes.
If there's something I'm not thinking here of please let me know.
