How relevant are moving averages for these leveraged ETFs? If applicable, what is the most efficient/accurate moving average to use and with what time period when looking at a 2-4 day outcome? Also, how do the prices of these ETFs change under high volume (like today, for instance)? I am having trouble comprehending how it is that the ETF can maintain its pricing integrity under a flock of heavy buyers or sellers. Is there a lot of institutional arbitrage going on with these instruments?
