hi All,

I am trying to create a table 

trade:(sym:n?`sym;time:10:30:00.0+til

n;price:n?3.3e;size:n?9;ex:n?ex);

Can someone please tell me what is wrong with the above statement?

Thanks,

Nitin

Hi,
This table will work fine if you define your sym, ex and n variables as per the below code:

…
q)n:5
q)sym:AB`C
q)ex:.Q.a

q)n?sym sym$CBCAA q)10:30:00.0+til 10:30:00.0+til n 10:30:00.000 10:30:00.001 10:30:00.002 10:30:00.003 10:30:00.004 q)n?3.3e ^ 2.585116 1.352855 2.01591 1.642242 1.34889e q)n?9 8 1 5 4 6 q)n?ex "gbyfe" q)trade:([]sym:n?sym;time:10:30:00.0+til n;price:n?3.3e;size:n?9;ex:n?ex)
