We'll be choosing horses in 3 different categories (4yo+, 3yo, 2yo) and there'll be a minimum and maximum number of horses you can choose and a minimum and maximum amount of money you can spend in each category. So yes, we will have a different number of horses.

As for that trading idea, it sounds okay in theory, but I don't know that it would really work. I think it might just confuse things. In any case, if someone had a horse which was going well, then they wouldn't want to get rid of it. And if someone had a horse which wasn't going well, then nobody else would want it.

So, I don't think I'll be using that idea, not quite how you explained it anyway. There will however be two further trading periods during the competition, the first one just before the big Melbourne races, then another just before the Golden Slipper.
