      Hi,

      I've throughly checked and I could confirm that there is an issue with resampling when RollOver data is used. I'm using three datas,

      data0 bt.feeds.IBData for SPY Index
      data1 bt.feeds.RollOver for SPY OPT Calls
      data2 bt.feeds.RollOver SPY OPT Puts
      For simplicity I added just one strike to each RollOver

      I tested with and without RollOver for data1 and data2 and below are the outputs in each case. I'm printing in ibdata.py in def _load_rtbar so you can see date2num timestamps and match them in each case.

      Issues I observed are

      • Data is processed in batches for each data and not all three datas for every rtbar like in case of second output without RollOver. I checked IB logs and can see that data is sent for all three datas every 5 seconds in both cases. In second output you can see prints for data0, data1 and data2 for every rtbar (5seconds) In case of first ouput with RollOver you can see them in batches

      • Data is being reported a minute later sometime. Check line after 737699.800636574 in both cases. In case of without Rollover Data for 2020-10-02T00:43:00 is being reported correctly with Close as 337.02. Whereas in case of Rollover after the same date2num 737699.800636574 data is being reported for a minute old 2020-10-02T00:42:00 with close as 336.91

      Any help with this bt.feeds.RollOver resampling is much appreciated.

      @backtrader @vladisld Any inputs please

                                            With RollOver Data

          Request your time and inputs.

          Honestly, I hardly understand what you are trying to achieve and what is the issue. RollOver data feed is intended to return the single data feed consisting from the slices of number of sequential future contracts. Since you are using options and real time data feed, than it is possible that RollOver data feed is simply not suitable for you.

            @ab_trader Yes, I'm using RollOver to create a single feed with multiple OPTs like mentioned in the document Rolling over Futures
             and Blog Post

            In my code below, I use data0 for SPY STK and data1 for SPY OPT (Calls) and data2 for SPY OPT (Puts). For testing purposes I just included one option in each RollOver. I use it for multiple options in each Rollover to create a single data feed. In case of Futures we RollOver based on expiration and here I use conditions to RollOver based on price or volume.

            data0 = IBDataFactory(dataname=args.data0, **datakwargs)

data1List = getOptionsList(args.data1)
d1temp = [IBDataFactory(dataname=data1List[i], **datakwargs) for i in range(0, len(data1List))]
data1 = bt.feeds.RollOver(*d1temp, name='Data1-Roll')

data2List = getOptionsList(args.data2)
d2temp = [IBDataFactory(dataname=data2List[i], **datakwargs) for i in range(0, len(data2List))]
data2 = bt.feeds.RollOver(*d2temp, name='Data2-Roll')

            This is working fine and I'm able to fetch and use data but I see resampling issue like I mentioned in my original post. For easier reading the debugs, data0 is in price range 333.xx, data1 is in price 2.xx and data2 is in price 1.xx

            Please let me know if you need further information. Thanks for your time.

              I'm printing in ibdata.py in def _load_rtbar so you can see date2num timestamps and match them in each case.

              If you use bt as expected i.e. print logs in the next(), but not somewhere deep in the bt scripts, will it returns the same issues?

              Also would be nice to have the full script without any excessive details. Resampling was mentioned, but there is nothing shows that it is there.

                @ab_trader Yes, logs in next() led me to put debugs in bt to check for the issue and I was able to nail it to the case with RollOver included. I see that RollOver is hardly used by anyone especially for Options, so I changed the way of handling this and avoided RollOver in total. Without RollOver data looks fine.

                Appreciate your time and responses. Please continue your outstanding and support and help.

                Thanks
