I found the volume data issue on cash Forex. If I use range or renko bar , the OBV is showing scale of thousands M normally which is as expected. But if I use minute bar, its scale is low number, but when new bar closes, it reported thousand M, so all historical data becomes just one horizontal line. What is the cause and how can I resolve it? Futures instrument does not have such issue.
Thanks.
Regards.
