  Maybe there's no volume tradeable, you can check the origin data first

  hmm, seems like the patch either doesn't work or missing. it should have looked like the following log: **20:37:31:657 -> 4-2-16777223-10225-Bust event occurred, current subscription is deactivated. Please resubscribe real-time bars immediately.- **20:37:31:982 <- 51-1-16777223- **20:37:31:989 <- 50-2-16777224-6248713-FFIV-STK--0.0---SMART-NASDAQ-USD-FFIV-NMS-5-TRADES-0- 20:37:32:349 -> 50-3-16777224-1600461445-120.84-120.84-120.84-120.84-0-120.84-0- 20:37:35:493 -> 50-3-16777221-1600461450-13.80-13.80-13.80-13.80-0-13.80-0- 20:37:35:494 -> 50-3-16777224-1600461450-120.84-120.84-120.84-120.84-0-120.84-0- 20:37:35:494 -> 50-3-16777217-1600461450-59.93-59.93-59.93-59.93-0-59.93-0- here the 51 code stands for CANCEL_REAL_TIME_BARS and 50 for REQ_REAL_TIME_BARS messages You may try to insert some prints in ibdata.py in the error processing code around lines 513-518 I guess. The code there looks like the following: elif msg == -10225: # Bust event occurred... self._subcription_valid = False if not self._statelivereconn: self._statelivereconn = self.p.backfill self.reqdata() # resubscribe continue and see if the code flow actually enters this region.

  Thanks for answering. Finally, I found out that trades are completed only when the position of the asset turns 0. Thanks again.

  portfolio value = cash + value of open positions. In you case: portfolio value = (50 - 22.27) (cash) + 21.35 (open position) = 27.73 + 21.35 = 49.08

  @btr I just asked where your misunderstanding was in the other topic. Thanks for clarifying. In the other topic the OP knew the optix lines. In your case, you would simlply add in the column names of your dataframe.
