Hello, If you think about it, it's not that weird. From your example, you plan to take profit and also immediately go short at the same level (sell 3 on position of 1, ends up -2). Also, that short

That is how bracket orders are supposed to work. You can search our archive since we had lots of discussions about this before. One that comes to mind from a couple weeks ago can be found here (

hello community, I am facing a problem with generating bracket orders. lets say i'm generating a bracket order with parent,take-profit,and stoploss. i'm sending the order with different quantity for

How do i subscribe to *TickByTickLast* and *TickByTickBidAsk* both for the same Contract/Instrument? If I do reqTickByTickData(ticker, contract, "Last", 0, true); reqTickByTickData(ticker, contract,
