Bloomberg BDH function with ISIN

The problem is that an isin does not identify the exchange, only an issuer.

Let's say your isin is US4592001014 (IBM), one way to do it would be:

• get the ticker (in A1):

  =BDP("US4592001014 ISIN", "TICKER") => IBM
  

• get a proper symbol (in A2)

  =BDP("US4592001014 ISIN", "PARSEKYABLE_DES") => IBM XX Equity
  

  where XX depends on your terminal settings, which you can check on CNDF <Go>.

• get the main exchange composite ticker, or whatever suits your need (in A3):

  =BDP(A2,"EQY_PRIM_SECURITY_COMP_EXCH") => US
  

• and finally:

  =BDP(A1&" "&A3&" Equity", "LAST_PRICE") => the last price of IBM US Equity
  

I had the same problem. Here's what I figured out:

=BDP(A1&"@BGN Corp", "Issuer_parent_eqy_ticker")

A1 being the ISINs. This will return the ticker number. Then just use the ticker number to get the price.
