The very same coin can look like it is rocketing upward when you zoom into the last few hours, yet clearly sliding when you zoom out to the last few months. Both pictures are true — they are just different time-spans, and which one matters depends entirely on the kind of trader you are.
SeerSignals works out its signals on eight of them: 15 minutes, 1 hour, 4 hours, 12 hours, 1 day, 3 days, 1 week and 1 month. A quick in-and-out trader lives on the short spans; someone investing for months barely glances at those and watches the long ones instead.
The rule of thumb worth remembering: shorter spans react faster but cry wolf far more often; longer spans are slower to turn but much more trustworthy when they do. And when several different spans happen to agree at the same time, that is a far stronger hint than any single one on its own.
