Disliked{quote} Another subject worth investing in is parametless system. it is in effect the same as walk forward optimization (wfo); but much more stable. I found WFO not stable over time. https://www.reddit.com/r/algotrading...ss_strategies/Ignored
Ernest Chan: "Lately, I begin to understand what a trading model with no free parameter means. It doesn't mean that it does not contain any lookback period for calculating trends, or thresholds for entry or exit. I think that would be impossible."
As far as I'm concerned a parameterless strategy has no parameters. A tradng model with no free-parameters isn't the same as a parameterless strategy. Chan is wrong when he states he thinks it would be impossible: a simple system that buys at S2 and sells as R2 as long as the last three bars are white would be a parameterless system.
Unless I am missing something.
