Why am i seeing a difference in Data?

I have Daily fx's charting software up the free stuff and a UWC metatrader 4 demo account up both a 4 hr and the data is different? Which should i trust?

I was assuming that the demo account is wrong even the time stamp on the bottom is wrong is there anyway to adjust this to actually be accurate. I have a live FXCM account but it doesnt provide 4hr bars.

Any suggestions would be appreciated.
Thanks ahead of time.

it is because of the time zone difference. different broker, different time zones, different shape of bars. and remember, it is all to the disadvantage of the "small" uninformed trader

Lol so which should i trade off of im assuming the American broker data feed because it seems to actually yield winning trades and the European feed looks like retardation in bar form.
