I have a question I hope we could discus here. I'm wondering how I should solve the following situation. I have a few systems, one is good when markets are trending up, the second is good when markets are trending down, and the third is good when markets are mostly going sideways. I would like to know how I can decide which system to trade when markets are in one of the three scenarios - up, down or sideways. By looking at the chart in hindsight, it's easy to point out where it would have paid to use which ever system. By looking at the equity curves for the systems and comparing the results to what markets were doing at the time clearly tells what would have paid to focus on during the up, down or sideways markets. To do it live is much harder. Maybe a moving average could do the trick - whenever it is pointing up or down, I know which one of my systems are the best choice. but this would require means to measure how much it is trending up or down. In a sideways market a moving average is still always pointing north or south too.... how do you measure that? And is it a viable solution? This would probably lead to getting in late, wouldn't it? Do you have any better idea, please share. I'm a systems guy so I guess I could incorporate some trading rules - if MA is pointing up so much, then use system 1 if MA is pointing down so much, then use system 2 if MA is not pointing up or down so much, then use system 3 then the rest of the rules for each system. Hope you have some experience or thoughts about this!
