I certainly think that there are many, many more opportunities intraday. However, I suspect that most retail traders that day trade are doing so because they believe it to be less risky due to some of the features that you mention. The problem is though that your question may be flawed a bit since you ask about catching the big moves intraday. I don't believe that that happens as a rule. I put forth to you that most retail day traders are engaging in quickly taking profits, using breakeven stops, using no stops and scaling in/out--------3 of these are specifically designed to choke off big winners. In addition most intraday traders are not nimble enough to trade on the short time frames. So, there may be more opportunity, but most of this may be missed by the retail trader whereas the outraday trader will have more time to reflect and make decisions and catch more of those setups. CAN you be more profitable when short term trading? Yes. Will you? Most likely not.
