  Hi , even though the badTrades was created as per the requirement still can’t pass the exercise which throws the below error . can that be explained. Or can the requirement be elaborated further.

   

   

  badTrades:select from (update exQuality:classifyTrades[tradeContext`side;tradeContext`price;tradeContext`ask;tradeContext`bid] from tradeContext) where exQuality=0b //your code here - or work in the scratchpad ?Scratchpad

  Hi  , I have altered the code to a single input function and getting the desired output as provided above but still i am not able to pass the exercise.

  classifyTrades:{[x] side:x`side;price:x`price;ask:x`ask;bid:x`bid; ?[side=`B;?[price<=ask;1b;0b];?[price>=bid;1b;0b]]}
  update exQuality:classifyTrades[tradeContext] from tradeContext

  badTrades:select from (update exQuality:classifyTrades[tradeContext] from tradeContext) where exQuality=0b

   

   

  even though i could get the desired output I cannot pass through
