    <![CDATA[<strong>Author:</strong> <a href="http://www.bullcharts.com.au/forum/member_profile.asp?PF=5459" rel="nofollow">Z2195067</a><br /><strong>Subject:</strong> 1036<br /><strong>Posted:</strong> 26&nbsp;Aug&nbsp;2020 at 10:30pm<br /><br /><div>Fellow BullChart/TradeSim users,</div><div><br></div><div>Having familiarized myself with TradeSim Professional Trial edition over recent months, what is clear to me with using TradeSim as a proper back-testing tool is its ability to handle Survivorship Bias (SB). As Dave states in one of his articles, SB does make a difference to the bottom line and NOT including it in one's back testing plans can overstate potential returns and overall performance.<br></div><div><br></div><div>Unfortunately Dave has not updated either the User manual or functionality in TradeSim to account for the fact that the S&amp;P Lists are no longer available free-of-charge on their website as they were years ago. This is a little disappointing, particularly since the software claims to provide this functionality - and although that is technically correct - the way one must now account for SB without the S&amp;P lists is somewhat more complicated than how he programmed it in.<br></div><div><br></div><div>I've managed to get ASX200 historical constituent lists going back to at least 2016, and possibly earlier. I know that BullCharts has the new issues and company name change lists from Actions&gt;Reports&gt;Company Name Changes OR New Issues etc. But I am unsure how accurate this data is. <br></div><div><br></div><div>So my question is: has anyone managed to actually set up SB that is fully functional in TradeSim using other sources apart from the now defunct S&amp;P website data? Does it work and on which Index have you set it up on? <br></div><div><br></div><div>Much appreciated,</div><div>bouralex<br></div><div><br></div><div><br></div>]]>
