comment compute FX forward from broker's data
@cf16: literally go on Reuters, or on their webpage, if you do not have Reuters EIKON. Look at EURUSD, you will see a quote like 1.3060. This means that the pips have to be divided by 10000 because (by convention) they are added to the last digits of the FX quote ...

comment Separating the wheat from the chaff: What quant methods separate skillful managers from lucky ones?
I saw another interesting approach where some researchers (I lost the names) looked for serial correlation in returns within a group. Interestingly they found more serial correlation in negative results than positive results.
