RE: [amibroker] Want CCI to range from 0 to 100

[MarketMonk777]

Pretty fancy graphics you have attached.       This is a classic engineering problem involving rescaling one range to another.   The basic equation is:   Y = mX = b where Y is the CCI_N (CCI New 0-100 range) m is the slope X is the CCI_O (CCI Old -100 to 100 range) b is the y offset   Is goes that the New CCI is what we want so it is on the Y axis and the old CCI is what we have and it goes on the X axis.   So the slope is the change in Y over the change is X or: Delta Y = 100 - 0 or 100 Delta X = 100 - (-100) or 200 so m = 100/200 or 1/2 or .5   the Y offset is the value when x=0 (where does the line cross the Y axis) which is 50.   so the equation is:   CCI_N = ( .5 * CCI_O ) + 50   To test this let's plug in some numbers.   CCI_O = -100   CCI_N = .5*(-100) + 50           = -50 + 50           = 0   CCI_O = +100   CCI_N = .5 * (+100)  + 50           = +50  + 50           = +100   So all you have to do is take the standard CCI indicator and rescale it to the new CCI_N range and plot that instead.   Regards,   Dave From: amibroker@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of mrdavis9 Sent: Monday, July 10, 2006 6:52 PM To: amibroker@yahoogroups.com Subject: [amibroker] Want CCI to range from 0 to 100 I would like to have a CCI(50) , and also a CCI(100) that ranges from Zero to 100, in lieu of the typical CCI range of negative 100 to positive 100.   This formula balow comes from Investor/RT Tour   ==================== TP = (HI + LO + CL) / 3     TP stands for Typical Price MATP = MA(TP, n)     n = CCI Period     MATP stands for Moving Average (Simple) of Typical Price     where n = CCI Period     MDTP stands for Mean Deviation of Typical Price   CCI = (TP - MATP) / (MDTP * 0.015) ===================================== I bet that Dingo knows how to  change this formula so that  it will oscillate between zero and 100.   Later Ron D.   __._,_.___ Please note that this group is for discussion between users only.
