This is all very, very early stage but I really like the direction!

It just built me the following ranking system (in the first one there was a mistake in the XML Structure, I copied an existing ranking system and told it to use it as an example. I had to correct it a couple of times more, but in the end, it worked well!).

Backtest on the SP500 Universe, cap weighted (no buy rules, only on rank sell rule Rank < 80).

I would say, o.k. for 20 min of work ;-)

Best Regards

Andreas

P.S. Here is the XML Format of the ranking system, you can copy it via the text editor of a ranking system.
