I don't seem to be able to get TR.FOLastTradingDate for some rics using the Python API. I'm able to get it through DIB though. The strange thing is once I have looked it up using DIB, it becomes available through the Python API. Maybe it is cached somewhere? The main question is why can't I get this field TR.FOLastTradingDate for example for the following rics:
ADZ6^1, ADZ5^1, ADU8^1, ADU7^1, ADU6^1, ADM8^1, ADM7^1, ADM6^1, ADH8^1, ADH7^1, ADH6^1, CN7^1, CK8^1, CK7^1
