Quote from Visaria:
Yes, I have made money for many years using spreadbet companies.
First of all, they are not brokers, they are market makers. Their prices are based on the underlying market. Their prices are not different from the underlying. If they were you could arbitrage them with the underlying market. I would be rather pleased if they were since i would arb the crap out of them.
Most people lose money with SBs, just the same as most people lose using the underlying markets.
can you explain your arbitrage stratergy.
as for SB, from most people i heard the brokers cancel you out of positions automatically.
