Dear all,

I fixed it.

for those who encounter the same issue, there is the correct schema:

meta tradeContext

 

c        | t f a 
---------| ----- 
date     | d 
option_id| s   p 
trade_id | C 
time     | t 
price    | f 
qty      | j 
side     | s 
edge     | f 
exch_id  | j 
broker_id| j 
bid      | f 
ask      | f

 

good luck
