Once I could get 3 figures on at bet365 no probs , these days my stake levels are fk all in comparison most of the time but even at that level bet365 is a no no because I'm generally limited to a max £10 take out.
The uk tote exactas and trifectas are on avg better prices than the forecasts and tricasts at the bookies, I have the data for both sides and have it tracked year by year.
If the tote tracked bsp instead of isp, I think they'd attract a lot more money, but I wouldn't agree with an api being in place so people/syndicates could pile money in at the last second, or if there was it shut down 5 mins before the off so they can't just fk it up for the rest.
I have my own set of rules re when I want to take a price, and I want the best possible price for my bet and it's generally a case of that is at an exchange
e.g. I backed Gold Old Days in the 1815 Chelmsford tonight, I took 2.5 on the exchange, it's now 2.16 there and a max of 2.2 elsewhere. It may even drift out again, or lose regardless, we'll see.
If you don't want people taking a price , fk off and only offer isp to everyone or just fobts and cartoon races cos you ain't a real bookmaker, the fact I took the view it was likely to shorten is all part of my analysis that I felt re it's chances of winning.
