Как управлять временем жизни стоп-заявки и как её снять по trans_id?

trans_params = {
 ["CLASSCODE"] = class,
 ["TRANS_ID"] = tostring(trans_id),
 ["ACTION"] = "KILL_ORDER",
 ["ORDER_KEY"] = что-то непонятное
 }
 
 sendTransaction(trans_params)

local transaction={
      ["TRANS_ID"]= tostring(trans_id),
      ["ACTION"]= "NEW_STOP_ORDER",
      ["CLASSCODE"] = class,
      ["SECCODE"] = security,
      ["OPERATION"] = direction,
      ["QUANTITY"] = tostring(volume),
      ["STOPPRICE"] = tostring(stopprice),
      ["PRICE"] = tostring(dealprice),
      ["ACCOUNT"] =tostring(account)
                ["EXPIRY_DATE"]="GTC" 
   }
