Not sure of your question, but I *think* you're describing any oscillator (Lane's stochastic, Money Flow Index, et al.) -- they're not so much *giving* H/L, as *utilizing* them as an overall package. And if you want it all on one graphing? Wilder's ADX/DMIs do great things.
Thanks. I'm actually looking for an indicator like ATR, but instead of absolute value, it gives % value. I want to how much a stock moves each day relative to its price.
Look for APTR (Average Percentage True Range), it is found on many platforms these days. The formula is (Average True Range/Close)*100. If your platform does not have this you can setup a formula in Excel or Open Office, or do it by hand with a calculator - all you need is the ATR and last price. In this example APTR gives the average daily percentage change over the last 10 days from stocks in the S&P100.
