I went for a walk in nature yesterday and was walking along the river.  The ice had recently broke free and the river was flowing fast.  I walked past an area where there was a very small back-eddy, a backwater reversal.  I thought at the time, that's the same as different time frame in charts.  If all I was looking at was the direction of the backflow I would not see that the remainder of the river is actually flowing in the other direction.  Reminded me of the importance of looking at multiple time frames depending on your objectives and risk tolerance.
