Do you have to update commissions in
ONE after each trade is filled in IBKR ?- Unfortunately yes, just so I know what my true P&L is.
Is their anything i need to look out for to get both platforms to be as close as possible numbers
wise? I tend to keep my trades separate in ONE, so that makes it easy for me to track the P&L of each trade. A double calendar is just 2 separate calendars, you know what you paid for them, ONE gives you the mid price of the calendars, which is what you will see in IB, albeit, you may have to give in a bit if you want to execute, so you may not get the exact mids.
Have you come across ReverseCal in IBKR? Is that just another fancy name for a Calendar?In IB if you buy the front month & sell the back month , IB will show the trade as a reverse calendar, so if you have a calendar in ONE and send it to IB, it will show up as a Reverse Calendar, confusing , I know, but that's IB. To avoid this confusion, when closing a calendar trade, don't send thru ONE, just execute directly in IB.
Does your
ONE display updated EOD data at the end of each trading day? mine doesn't. ---Thats one of the drawbacks of ONE, no EOD until next day & if its Friday, have to wait till Monday.
IB not perfect, ONE not great, but we just have to try as best as possible to trade round these deficiencies. I'm sure there are much better systems available, but I can't afford them.
