I'm working on market trends. I have daily prices for 33 assets from different markets. I was wondering if there is a way to cancel the effects of different opening/closing times.
I have been told that a moving average over four days would be enough; I think a weekly moving average should improve many thing. As I observe a 50-day moving average to observe market trends, I don't really see the point in doing this first moving average.
Is there any literature about this topic? Are there simple solutions to cancel the effects of markets desynchronization?
