Hi Stix,

scratchings do change his prices but I can't be certain if this is done immediately. However, if a scratching is still shown as a runner in his market, one can manually load that scratching(s) on the worksheet by clicking-on to the Dinc column (right hand side of the screen) for any horse. This will immediately remove the horse(s) from his market and recalculate an updated price for all remaining horses.

I think the most important filter/factor in his market is that horses resuming from a spell can generally be heavily penalised.

Good luck with it.
