ISTR support & resistance FAQ
What are ISTR's support and resistance levels today?
From end-of-day data (as of 2026-08-14), ISTR's nearest computed levels bracket its $30.95 close; the tables on this page list floor-trader pivots for the daily, weekly, monthly and yearly ranges plus the 52-week extremes.
How are these levels calculated?
Classic floor-trader pivots: the pivot point is the average of the prior period’s high, low and close; support and resistance rungs are symmetric multiples around it. Each timeframe uses its own completed prior period. The 52-week high and low come straight from the price history.
Are these levels predictions?
No. Pivots are arithmetic on past prices — reference levels many traders watch, which is the only reason they matter. Nothing here is a recommendation.
