Backing first 3 favs in running.
Hi, as a newbie I can't seem to get the hang of fixing the favourites. I'd like to back the first three favourites in running, it works most of the time but occasionally goes haywire and seems to back anything and everything. I use the rule fix the order of the market selections and I wonder if I'm using the wrong timing? The other rules I use are the place back bet in position 1 in order of favouritism and the same for positions 2 and 3. Where am I going wrong?
