IB tickTypes in tickPrice event

For the tickType, I read that:

1 = bid
2 = ask
4 = last
6 = high
7 = low
9 = close

I also received the following codes from 14 to 20 with prices:
Can anyone tell what these other code mean exactly ?

14 285.50
16 382.90
15 285.22
18 382.90
17 201.15
20 429.19
19 161.00


(from BIDU observed today 18.26.35 (it) )


thank you!
