Re: [amibroker] What's wrong with my formula (trouble with custombacktest)

["Louis Préfontaine" <rockprog80@xxxxxxxxx>]

Hi Graham,

Wouldn't it be implicit to AB that if I set a maximum of 5 trades (SetOption("MaxOpenPositions", 5 );)  each would be about 20%?

Anyway I added SetPositionSize( 20, spsPercentOfEquity );  and it works well...  But I thought this was custom backtest;  I still have a lot to learn I guess! 

Thanks for your patience!

Louis

Now we can answer what your real problem is.
You need to specify a Positionsize, if not defined then AB assumes 100% of equity is used per trade, thus only one trade at one time

Well, sorry for posting "code that has no relevance at all"  (still, in the manual it looks like setoption has a relevance to customizing backtesting...), but I just can't see what is the problem.  

If I use auto-analysis and try to backtest my list of tickers, it won't do more than one trade at a time EVEN IF I click on "settings" and change the max number of positions to 10.   The only way I could have more than one position at any time is to use custom variables.  Maybe I have no clue about what it is, but that's why I am asking, dingo.
