    G'day Robbbbbbb, your intra-day price swing posts reminded me of some excel charts I used to do of intra-day price swings at a time when I was experimenting with day trades. Following is an example chart featuring BHP's intra-day price swings for the 3-4 months:

    2009-11-09 BHP chart

    The chart shows the actual intra-day price swing (high minus low), the % of the share price that swing represents, and a 10 day SMAV of the intra-day price swing (and 80% of the SMAV). What I found useful from the chart is that it shows quite clearly how large the intra-day price swing is, how consistent it is, and whether its trending smaller or larger.

    Thus if you wanted to trade BHP intra-day on a safe basis you just need look at the chart and say in October the absolute minimum price swing on any day in October was $0.30, while the average was actually closer to $0.50.

    Then using standard intra-day charting tools on say 1, 5 or 10 min timeframes you can pick the bottom or top and set a trade for the minimum price swing being experienced or for a trade with a slight risk of not hitting target use the SMAV or 80% thereof to set the target.

    I had a reasonable success with it but I have a day job so the problem I had was having the time to work it.

    Cheers, Sharks
