Prediction market trades are not imported for both API and CSV.
These can be added as standalone tickers however the nature of these transactions needs to be investigated first.
There is no immediate workaround at the moment.
If you prefer to treat the transactions as standalone trades with independent tokens, please rename the tokens as NULL1, NULL2 etc.,
If you prefer to track the actual USD spends and earnings from prediction market, please tag the USD spent and received as the results of the settlement as Realised P&L akin to futures.
