Hi everyone Just getting started in systems writing. I would appreciate any comments from experienced systems developers. I am working on EOD data. 1. I am finding that I _can_ develop potentially tradable non-discretionary systems; the problem is, the good ones tend to go off very infrequently. I am wondering - do those who trade these systems exclusively have a large number of different systems that each go off rarely? Of course the type of system you are shooting for matters - I am speaking here of what should probably be called 'swing' trading systems (although in my development work I have found that a swing trade is simply one which you are not stopped out of!). Part of my problem may be that I have this idea in my head that I should be able to devise a system that wins a large percentage of the time. I therefore work each system to the point that it produces a higher percentage of wins but triggers infrequently. 2. More importantly - I have found that the best stuff I have would be hard to trade, psychologically speaking - that is, it is very hard to devise a 'swing' type system that reliably goes off in every dip during a nice clean uptrend; it is easier to develop a system that goes off 1/2 way through up legs. What kind of an answer am I looking for here? Not a pat on the back - just want to hear from others who have been down this road and know what I'm talking about. Are your good systems 'hard' to trade in that they give signals in counter-intuitive spots? (Hmmm... what's counter-intuitive to one person might be perfectly reasonable to another, right?) I am using Metastock right now but the system tester in v 8.0 is not great; I am considering WLD but I would have to learn Pascal for that... any comments about the best system development program for non-programmers? Some of the posts here are obviously written by individuals with heavy programming and high math chops. That's not me - I am hoping that a good system can be devised by someone like me who substitutes hard work for high concept.
