QUANTCONNECT COMMUNITY
Hi all,
Been grappling with this issue for a while - when I call history on a bunch of FX pairs, the multi-index dataframe seems to have duplicate symbols, which don't allow me to unstack based on symbols. Have double checked and the list of symbols are unique.
Was wondering if anyone has faced the same issue before? Pasting error below..
