Total 353 bets, max bet $80, $130 max bankroll needed,  $135.77 profit

So you're back to level one and the bet is $1 again? Nice  Smiley

In your opinion, does increased volatility in odds give betters a chance to use it somehow? Or do bookmakers take a big margin because of this? I remember checking men's and women's tennis and in women's (where volatility is always higher) the bookmaker's margin was on average 8% (a couple of percent higher than in men's).

I don't think bookies really take advantage of this, with such volatility, you're most of the time concerned with market fluctuations rather than the house edge, and if they do use these fluctuations to cover a bigger share it's hard to look into, it's easy when you ahve a 1x2 result, it's almsot impossible without a script to check what the house edge is in when you have 10 horses with odds going up and down like crazy.
So, no I have no clue!  Cheesy

I will try to do fast check. I see this:


1. Hope And Glory (9) - 4.00

2. Lombardi Lass (1) - 3.80

3. Champ De Mars (3) - 7.50

4. Imabarbiegirl (4) - 6.50

5. Giza (6) - 4.75

6. Back In A Tik (7) - 61.00

7. Commandoro (Cool - 3.90

8. Consorting One (2) - 51.00

9. Really Satisfies (5) - 151.00

Hmmmm... I recalculated twice and the bookmaker's margin here is not small at all - almost 24%!  Shocked
After football and tennis, I find it hard to perceive such figures. Although in fact, it is very logical and fits into the pattern where the higher the volatility, the higher the bookmaker's margin.
