Would you be willing to share what main setting (like stoploss, no of trades etc)
work well for you? Do you allow systems that do not have a stoploss?
I think the exit criteria are sometimes risky. Some indicator do not give a
signal if the system is rapidly going down. It sure did work in sample but
OOS is a different story.
That sure needs understanding of the used indicators but
I do understand most indicators very well. I have been experimenting with and
optimizing them on huge portfolios in other software and some indicators that
used to work several years ago are now a different story.
What I also see happening more than once is a system which takes a position of 50k
that has a stoploss of >50k.
I often look at the result at the profit curve which should not bent down at the
end of in sample and the %/per trade, no of trades, draw down, linearity and profit/drawdown.
Most times I only set 2-4 parameters to search for systems and generate many times to find
I am not looking for the highest net profit as these systems are often curve fitted. I rather look
at the underlying ticker and if the ticker has several uptrends and downtrends IS and a linear profit
curve IS I trust these ones more OOS.
I still think a couple of months of data and few trades could cause curve fit in ProQuant.
I also can't set minimum profit per trade to less that 1% as the scrollbars are not precise enough.
To really evaluate proquant it would need to look at OOS results for several months
and it would need more history and generated systems per search.
But for a free app it is great start and I can't ask too much.
I guess I have to trial Studio and ForexSB.
