It should dawn on a person after looking at the charts for a while that the same patterns are being made on the large time frames as on the small. From that one ought to deduce that the same causes of market movements underlie the big as well as the small and any indicator or system that works for the big should work for the small. Breakout, double bottoms and tops, trend-lines, etc. are some that work on the large and small alike. So that becomes my first point of investigation when looking at a system or theory...can I use it on the 30 second and the daily or weekly? If not, it causes a problem with me. It reminds me of the physicists looking for the "God" particle...a thing that ties together the workings of the very biggest to the very smallest.
Since I work on such a small time frame I have taken the RTT and applied it using the 1, 3, and 5 minute charts as well as the others because even the 240 can lead to a long wait when using the 30 second chart. When the beans actually have a decent day I'll apply the dow on the 30's time frame.
But...to me, the most valuable thing on this time scale is the trigger. If either the cross or cod doesn't come together with the tl break on the 30's and it looks like it is stalling out and not completing the move, I just bump out to the 1 or 3 minute and wait for it there. POW...ZAP...BAM!
Impressed, I am. :-)
