In excel I can get implied volatilities using:
=RHistory("COM37000T8;BL218000I8;1C400I8;1SM380G8";"IMP_VOLT.Value;IMP_VOLT.Timestamp";"START:"&$E$2&" INTERVAL:1D";;"TSREPEAT:NO CH:Fd";F4)
However when I try to use
df=ek.get_timeseries("COM37000T8","IMP_VOLT.Value") I only get nan s as returns
If I try to use df=ek.get_timeseries("COM37000T8") i get values in the CLOSE field but no volatilities
