Hi, the problem seems to be easy but I am stuck. I want to have 2 classes CQ and CI. CI in its constructor searches within an array of pointers (ArrCQ[]) to existing instances of CQ whether there is one that matches. For this "match-check" CQ has a

Published article Enhancing the StrategyTester to Optimize Indicators Solely on the Example of Flat and Trend Markets 
It is essential to detect whether a market is flat or not for many strategies. Using the well known ADX we demonstrate how we can use the Strategy Tester not only to optimize this indicator for our specific purpose, but as well we can decide whether this indicator will meet our needs and get to know the average range of the flat and trend markets which might be quite important to determine stops and targets of the markets.
