I don't see this problem with their version 5 now, and with version 4 the major issue i felt is lack of Indian time zone, were server are set at offset of 30 mins, which i think is causing the different high low for same bars when you are comparing them with Indian time zone based charts, if you compare open, high, low and close of the day you can see it don't differs.
Right now i am getting more comfort from version 5 than 4 and converting indicator from 4 > 5 is not difficult job for me as
i have many coder friends who can get it done for me, for those indicators that i do use and i am waiting for their backfills added to version 5 so that it rockss for me.
