[amibroker] Re: Howto backtest only the top 10 stocks even though your filter list gives you

["mbluhm2001" <mbluhm2001@xxxxxxxxx>]

Mike,

Thanks for the reply. The way "I think" it works is that it will take the 100 stocks, for example that met the entry criteria, and sort them by the top HV100. It will then take the 1st 10 stocks that triggered a buy signal no matter how far into the list of 100.  

So what I want is to limit the triggered stocks to only the top 10 HV100 stocks and not the whole list.  

Hope that makes sense. 

Thanks for your response,
Mark

If i have more than 10 stocks I want to only take the 10 stocks that have the highest HV100. This is easy to see each day when i scan but I want to back test this and this is the problem. Effectively i'm using a filter that gets me the initial list of stocks and then i want to take that list, scan it and then take the top 10 HV100 stocks.
