However, I find that is very helpful in shorter timeframes, though I cannot post them here as ideas (though lower down I will as a comment with snapshot).
Here I have changed the Value Area from the default 70 to 38.2, which I find creates a channel around the POC and often is very helpful at showing breakout areas. Generally speaking, the shorter the time period of the chart, the tighter this band can be, though I prefer Fibs. For the 30 min I would use the 61.8, though to be honest I tend not to use the Value Area much when it is that fat.
Anyway, that is the idea: try using a tighter Value Area with a shorter time-frame chart.
2 min chart with default 70. Actually this example shows the 70 being sort of more helpful, though the tighter one does provide a few good break-out trades to the downside which the 70 contains. Personally I would like to be able to draw both, and maybe will set up a double layer just to see....
That was a good idea. The outer 70 is Lime, the inners 38.2 are dark green. Here you can see that those break-out trades around 100:30 to 13:30 which weren't much good happened each time the 38 and 70 areas were close together (and the 70, which is widely monitored, contained the failing probes for further sellers). When there was a nice day-tradable gap between the inner 38 and the outer 70, you to a nice move down to the 70.
So again, I think it is worth considering different Value Area widths/levels when dealing with shorter time frames.
