hi said. yes your right
but
the order number mix up is very interesting. it does not issue sell order for everything in the csv file. it depends weather the order ID has been used before somewhere. it gives very strange behaviour based on old values stored in the previous used order ID.
in the asx i had a batchtrader issue a sell order for ~$60 when the actual price was around ~$2. this was not a problem in the asx because the order was never filled and subsequently cancelled. but in the us its very dangerous due to MOC orders being issued instead of sell limit.

anyway… levente seems to have fixed the problem and issued a new version. lets see how we can break this one

I use my Batchtrader in much the same way. I have instance 1 and 2 (1 is for placing normal orders and closing if too many are activated and 2 is MOC). I run them both on the ASX under the one IB account number. Then I close them down, and reopen them to run them both on the US markets a few hours later.

Is that effectively what you are doing Darryl?

its not what i was doing when the problem developed. i was using the same id number for both asx and us. big mistake :dry: i did initially use different id numbers with the original versions of batchtrader but somewhere in the process of upgrades i became complacent.

it is what i have put in place now though. just need to make sure that batchtrader uses a different id number for trading us and asx. also i will make sure the different instances are not running at the same time

When you say ID number do you mean the Order reference number? The one you can change in the settings file to differentiate between two Batchtraders running at the same time with different systems?

yes exactly

I setup tws and batchtrader after the close around 5pm each ight for the next day. When i looked yesterday before the open, i had 3 apparent fills in certain stocks on batchtrader. But the size and price of the position were not even close to my order even if there was a fill (which there wasn’t)

Anyone else had this?

you can check the log file to see what were the messages that led to this

This was before the open ? The preset for out of hours trading hasn’t accidentally been ticked has it ? Only other thing I could think of is if asx stocks somehow were mixed up with US ?

[TrentRothall]

I never got filled in IB it was only batchtrader showing a fill. Hasn’t happened since…
