High and Low difference calculator

[Ravi Dahiya]

Hi Friends,

I would like to know about an indicator that can calculate either price difference of a candle's HIGH and LOW or it can tell me in % the difference of HIGH and LOW.

For Example:

5 Min Chart. Any Equity Cash or futures Share.

1st candle: high 102. Low 99. Open 100.

H & L diff: 3.  And in % = (102-99)/100 * 100 = 3%

2nd Candle : High 105. Low 101. Open 102.

H & L diff: 4.  And in % = (105-101)/102 * 100 = 3.9%

Thanks in Advance.
