AggZ: Another Composite Trend/Mean Reversion Indicator

March 19, 2010

Here is a super simple indicator with dozens of applications. Similar to AggM, the AggZ is a composite trend and mean-reversion indicator rolled into one. The concept of both is to anchor a long term trending measure to a short-term mean-reverting measure so that you can have an indicator that can be traded for both long and short-term intervals. The AggZ did 20% CAGR over the last 2000 bars on the CAGR using dividend adjusted data on the SPY. The calculation is dead simple:

AggZ= (-1x( 10-day z-score)+(200-day z-score))/2

where z-score = (close-sma (closing prices over last n periods))/(standard deviation( closing prices over last n periods))

buy above 0, sell below 0 as a basic strategy.

Users may try different variations of z-lengths as well as entry/exits. On a side note, expect DV Indicators for Amibroker to be out next week—we are finally done! More information to follow.

    duh, -1 x (

    So used to never seeing a multiplication sign in equations, sorry. Will be neat to run this through a rolling genetic optimizer.

    Rumor has it that DV is days away from offering all indicators in Amibroker with an Excel plug-in and charting package to boot. Are those rumors true?

    I am using the “Zprob” function with Tradestation and can’t replicate the results:

    AggZ= (-1*( ZProb(value9, 10))+(ZProb(value9, 200)))/2;
