My system is automated using the recommended TradeStation-Collective2 interface.
Yesterday a duplicate sell to open order was placed by C2 causing a 2 contract short position to be entered instead of the 1 contract position entered in my platform.
I submitted a support request for the trades in question to be sure but it looks like a signal from the previous day carried over into the morning (see the dates below). Once the stop price was hit, both orders must have been filled:
63848720

C2TS: QCLU1 STO 1 price_stop_market=98.420000
My hunch is this was a disconnect/reconnect of TradeStation which sent the next day’s order into the after hours session by mistake. This should be correctable on my end.
Am I correct to assume this order wouldnât have expired until 5:15pm ET the next day?
Should this have been handled as a duplicate by the interface? Is there a case for entering two STO trades at separate times at the same price?
Can any other system developers using TradeStation or Collective2 staff recommend a solution to prevent this from happening again?
Thanks,
Chris

I have had exactly same problem. I requested C2 about improving TS connection, have some problems like this.
