I know Bob Volman trades spot forex, but I trade futures.
Since spot is different by the amount of forward points, I add the 00, 20, and 50 lines from spot forex on my chart.
So the purple lines on the chart are what the corresponding price would be on the spot market ( adding the forward points ).
Do anyone else do something like this ?
I trade futures as well, but don't do this. My main objection to this is the added chart clutter. To me it would seem to get too distracting having all those extra lines on the chart. I do have FreeStockCharts going on another computer that I can glance at quickly if I am worried about a level being in play, but usually don't check it that much unless the 00 level is in play.
Generally I don't pay too much attention to the numbered price levels, and worry more about actual S/R levels that price has tested in the past. To me the numbered levels just adds another layer of complexity. Not that I've been wildly successful with this method yet, and I could be totally out to lunch, but I just prefer to concentrate on finding good looking setups,
