Step 1 of 3
Period versus interval
Concept
The period controls how much history is visible. The interval controls what each bar represents.
Do this
Open SPY with one year of history and daily bars.
Why it matters
A trend can appear strong on one interval and noisy or opposite on another.
Common mistake
Calling a five-minute move a long-term trend.
