It appears that the behaviour for called bonds or expired futures has changed. I have started to receive multiple duplicate values.
For example the Lloyds 13 Bond (RIC GB040862072=) which has redeemed earlier this year returned an array of duplicate prices. It appears to have returned the final trading price as a result for each date in the time period which I requested prices for. This appears to be new behaviour because previously once a bond or future expired a null response was received.
Please can you advise what the correct behaviour should be so that I can adjust my error handling accordingly.
