Hey guys, I'm been stumped over how to find an accurate estimation of how many active traders (in all assets) exists in the world; I have dug through the financial reports of a lot of brokerages but they mostly state how many total customers they have (I suspect a lot are long term investors/inactive) and not how many were actively trading. There is a wide range of estimations on the web in various places for this kind of information but I can't seem to find one that was made with robust statistical methods and data collection. Does anyone know how one might find such information? +as a bonus, how would I find out how many active traders use Windows OS over Mac, or Iphone over Android? Thanks in advance.
