A question for the Index Future wizards

I follow the 'Anyone scalping the FTSE futures' thread closely during the day. The problem is I spread bet and wonder how closely my prices actually follow the futures. I've attached the charts of the DOW, DAX and FTSE from Friday (23/09/16). Could any of the adepts that day trade these futures tell me how close my charts are to theirs?

Cheers :thumbsup:
