I logged in again to test the suggested solution. Now I cannot reproduce the error, no matter if I define the function name or not

Hi Megan,

 

{[tab]
    //Pseudocode:
    //Performing an update will keep the original table
    //When classifying, need to first check the side
    //If side is Buy, then a good trade was bought for less than what the market was asking for
    //If side is Sell, then a good trade sold for more than what the market was bidding for
    //The vector conditional might prove useful   
    s: exec side from select side from tab;
    b: exec bid from select bid from tab;
    a: exec ask from select ask from tab;
    p: exec price from select price from tab;
    exQuality: ?[s=`B;?[p<a;1b;0b];?[p>b;1b;0b]];
    new: update exQuality from tab
    }
