I use amiquote for update from 2 different data provider: msn historical and yahoo! historical. the error rate in the data price is very high. ther are not only holes! This is not the difference casued by correction of divident and split. I use in the same database symbols from yahoo and msn, and I update from both. Can this causes some problems?
I read amibroker kb but there is same other way to obtain historical quote (for free) or same other tricks? Is non free data providerreally more accurate?
