Excellent site! I am starting to get the hang of using volume to determine turning points, using the Tradeguider MT4 plugin.
One excellent feature this has are the H-stops - stops based on volume and very useful for placing stops as the trend progresses. Once a bar closes beyond one of these H-stops, its a sign to look out for a change....or indeed a continuation, if price closes back in the trend direction. I hope this chart will explain.
Also, I find the last highest volume spike, draw a line across the top and bottom and wait for price to close either above or below those lines. But, if that closure is right at a support or resistance level...beware, price could bounce back into the area between the high/low lines and may break out to the other side.
As price reverses down on 4th Jan, the H-stops follow price nicely down. On the 6th price closes above the H-stop during the Asia session, indicating a possible direction change. Price is supported at the long H-stop towards noon, then makes its move up. H-stops following nicely as it goes up.
Notice how I've drawn horizontal lines at H & L of big volume bars. When price closes above or below these bars it USUALLY (no certainties in trading:-)) signals the direction of movement, with the opposite horizontal line as the stop.
You will notice that price does very occasionally spike through a red h-stop, then continues as it should.....but that's life:5:
I hope this will help people with their trading.
