You are right. Options and Futures markets are regulated and really protected (for the CME and members) in the US.
The reason I was asking about time frames is that I'm wondering whether it would not be more effective, given the relatively big moves on the Dow, to trade a sub-minute time frame, perhaps even down to 10 seconds, using smaller stop loss and taking profits early, that is trading the micro-movements rather than the bigger daily macro moves. Any thoughts on this would be most welcome.
Sounds like a good even spread of time frames. Seeing as you pretty much jump in threes and fours ( 5/15m/H1 ) have you ever tried a 1 minute to help pinpoint your entries?
