The CMO Filter was authored by Chande and Kroll for Omega Research 1997. A user defined filter is applied to the real and absolute sum of the difference between current price and last price. The quotient is over sized to create an oscillator with a range of 100 to -100. Adjustable guides are given to fine tune the trading signals. The user may change the input (close), period, filter and guide values. This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using CMO Filter
Fine tune the top and bottom guides to control the quantity and quality of the trading signals. CMOF values above 70 are considered to be overbought and therefore offer an opportunity to sell. CMOF values below -70 are considered oversold and present an opportunity to buy. If the CMOF peaks above the top guide a sell signal will be generated. Conversely, if the CMOF troughs below the bottom guide a buy signal will be given. The 0 line divides the bulls (above) from the bears (below).
