    BackTesting vs WalkForward

    walterjennings,...your knowledge of trading optimization seems excellent. Did you conclude this through your own studies, or did you derive it from folks like Robert Pardo? I am curious about your source!

    BackTesting vs WalkForward

    iagainsti,...sure your smart enough to know how to these indicators, but like most of use (myself included) it takes a little coaching. If you haven't done so already, consider these two web sites - I particularly like FM Labs, consider purchasing their code - they did a good job...

    BackTesting vs WalkForward

    Pardon my ignorance iagainsti, but indicators, lagging, leading or otherwise, would be components in your trading system - and you would always test against real historical price data. tell me this is always the case, or tell me when this would not be the case - I am curios?

    BackTesting vs WalkForward

    Back Testing; Curve fitting does not necessarily mean optimization. The curve will exhibit an optimum fit over a data set if and only if you chose the optimum settings from your test. The approach I have chosen, the approach I like for myself, consistently yields stable systems. The...

    BackTesting vs WalkForward

    The Evaluation and Optimization of Trading Strategies by Robert Pardo is an excellent book that you should consider having in your library.

    BackTesting vs WalkForward

    I have used both with good results. The issue with back testing is that you are prone to over optimization. Over optimization can produce a brittle system, one that fails when market conditions change slightly - as januson explained, you are curve fitting. I have found that...

    Trading is NOT a business

    Back to the subject at hand... TFTrader, There are a lot of successful traders and investors out there - it is a buisness. I don't beleive you even know what a trading system is. Try reading "Inside The Black Box" by rishi k narang. If you succeed in designing one afterwards, then...

    Trading is NOT a business

    I am looking at a blueprint I drew up of Jacks Trading System - its not bad. But it won't work, the problem - his signal generator (you know, that critical body of Logic that allows Jack to trade seamless from one pivot point to the next)...well... ...Its uses a Trilithium Powered Warp...

    Trading is NOT a business

    Hello, I am done with Jack, and no it wasn't an exercise in futility. Maybe I am just as insane as he is, but I do understand him, and I got the man pegged. I also figured out his trading system....it is actually pretty straight forward...I don't know if it will work... and actually I...

    Trading is NOT a business

    OK trendo - I finally woke up! As Promised... 1) the phenomena most apparent was the "bridging" of cycles 2) To check out the proper defaults, you test on all nested fractals 3) A default test reveals that the indicator works on all fractals and there is no bridging on any fractal 4)...

    Trading is NOT a business

    Hello Optionpro007, The statement was all inclusive. I found this to be the case when others tried to duplicate my own trading systems. Unfortunately my systems execute profitably on my app - and no other companies app - just the way it is - so I have found.

    Trading is NOT a business

    Until I know better I have no reason to doubt Jack - I will make my own decison about him - you and others have made yours. Regardless of how this turns out, his posting's have opened my eyes - I am looking at charts and their corresponding data differently - things I did not consider. I...

    Trading is NOT a business

    One More Thing Trader666 Your results are not surprising! I have found that unless a trading system is precisely documented - and not executed within the same environment that it was tested - the results can vary wildly. I am not trying to duplicate Jack's system, I am trying to see...
