Syntax error for nested condtionals in SQL

I’m pretty new to redshift and I’ve been trying to to do a nested case when condition here, yet I get a syntax error

ERROR: syntax error at or near “)”

in this line of SQL:

ELSE ROUND((last_bid * positions), 2))

I’m not sure what’s wrong, since I’m familiar with Python and I’m pretty sure this is how nested conditions work

SELECT 
    *, 
    CASE
       WHEN asset_type = 'EQUITY' 
          THEN (CASE
                   WHEN positions < 0 THEN ROUND((positions * last_ask), 2)
                   ELSE ROUND((last_bid * positions), 2))
          ELSE ROUND((positions * last_ask/100), 2)
    END AS MARKET_VALUE
FROM 
    base_report

Answer

You should end the nested CASE, like that:

ELSE ROUND((last_bid * positions), 2)
END
)
