I was short 10 ES, and own 17,500 sh of a $3.00 stock. I designated the stock "liquidate last". Even before I designated the stock as liquidate last, in the past TWS always closed out any short ES positions, and never touched my stock position. So imagine my surprise when last week, they sold off 2,500 shares of the stock, instead of touching the ES position. I complained to IB, and they responded that "liquidate last" is just a request, not a guarantee. But not according to the TWS USer's Guide. Does anybody have any experience with this? Thanks for any info!
