Does anybody know of a web based platform that I can chart crude on intraday? I have been using one free site that I really like, however after just comparing the prices on the chart to Sierra Chart I realized it has a tendency to be 1-5 ticks off on some of the bigger bars which can make a big difference obviously. I spoke with IB and their web based platform does show charting but the smallest time frame is 10 minutes I believe. I need the 1m and 5m chart. Does anybody have any suggestions for a web based site to see the chart? I don't mind paying for it, I just need something that is pretty accurate. Thanks!
