Question for the Oanda die hards: I was looking at the charting on their platform as an alternative to mt4 (yes, I know prices may not be 100% reflective of the broker(s) I use - looking at the longer time frame charts) and wonder why do they have 3 hr charting instead of 4? 4 is a standard on most every other charting package, from stocks to futures to forex. Why does Oanda use 3 hr? Is there a technical sta that uses 3 hr over 4? thx.
