Can anyone kindly recommend a system which can plot spreads in an OHLC format. Most systems plot spread & ratio charts as a singlemeandering line. My current system enables me to create a custom stock eg: WMT - TGT called WMTTGT Pair and it then plots the OHLC of the spread for that interval (i.e. daily or 5 min,etc) The system is just a little to buggy for my taste and am looking for other alternatives. Thanks
