If you opt for top flucs with a bookmaker, generally you have to place your bet well before the market is framed, ie before midday or sometimes up to 30 minutes before race time.

Once your bet is on you are guaranteed the top official fluctuation in prices for that race. Eg. If your horse opens at 3/1, then drifts to 7/2, then tightens to 5/2, you are guaranteed the 7/2. Similarly If your horse opens at 10/1 and tightens to 4/1, you get 10/1.

Puntz, you say a bet is a bet is a bet but if you accept 5/1 and that price drifts out to 7/1, you miss out on those extra couple of points. With Top Fluc, you are guaranteed the longer odds.

The drawback is of course having to place your bet so early. I've mentioned before why it's a service bookies provide but rest assured, it's not out of heart felt generosity for the punter.
