Typically for strategies you want to use a specialized software. Brokers are not very good at tracking your adjustment and definitely will not show the proper P/L for the whole life of the trade.At the first seconds of minute 14 he moves the upper leg. He does that often for a M3.4U. My question is how would you handle the adjustment with the TWS? Assuming the BF is initiated in the TWS as one combo order, would you try to keep the combo when you roll like this, or would you accept that the combo would be destroyed by first selling and then buying the leg?
With combo I mean the Butterflytrade is recognized as butterfly and shown as one position.
