Trade union democracy and efficiency
To make this system work, you need to be connected every single weekday to trade (and at around 8am UK time, then maybe adjust trade at 11am, then towards end of trading day). In other words, you need a reliable connection, and focus. If not, you can be sure that the days you are able to trade will be losers, and when you cannot trade, they will be winners. But we are all different, maybe thats your idea of relaxation. So if you happen to trial it in a bad month, your experience will be negative, and visa versa.
