Quoting tkimbleDislikedYes. Valid entry for you first question.
No. Always obey the indicators. In the case above, when the RSI goes equates to less than 50 and the price is 5 PIPs below the 5 SMA, take the short signal. In rare cases this can happen several times during the 30 min bar but very seldom and your subsequent losses would be minimized...
Hope this helps...
