Problem with the example trigger for HiLo

I mean the "Back on 'Card 11' in the first round, then either green up or distribute the loss equally."

Why dont it spread the amount when the first price is empty.

for example: I will back for 10€ in the first round but there is only 9,61€ for one price..
why dont it take the rest to another price??

Because you need to let it know that you want to bet at the best price to match rather than at best price available.

Change "current best" to "best to match".
