Anyone knows how igmarkets price their binary products? The binary product generally follows the index (binary index). For Sp500 trading at 950, what is the level the binary Sp500 Up/Dn trading at? If the Sp500 trading goes up or goes down 10 points how much the binary Up/Dn change? Seems the binary products reduce the open index price to a range from 0 to 100. Anyone know a formula or how to calculate the corresponding level the binary is trading from the index price level.
