Structure & Key Levels

The 24-hour chart showed a strong upward shift, with IOSTUSDT breaking above a key resistance level at 0.001570 and forming a bullish trend continuation. A descending triangle pattern was observed in the early session, which reversed after strong volume and price action. The 0.001620–0.001630 zone appears to be a new short-term resistance cluster, with 0.001600 as immediate support.

Momentum and Indicators

The 20-period and 50-period moving averages on the 5-minute chart are both bullish, with price above both. MACD showed a positive crossover, and the histogram was expanding in the positive range, signaling growing bullish momentum.

. RSI approached 73 but did not enter overbought territory, suggesting caution may still be in place.

Bollinger Bands widened during the morning hours in ET time, indicating rising volatility, with price frequently testing the upper band.

Volume and Divergence

Volume spiked during the 0415–0630 ET period, with a large block of 63,797,404.0 tokens traded as price moved from 0.001607 to 0.001585. This suggests a possible shift in momentum as price corrected slightly afterward. Turnover increased during the same period but failed to confirm further strength beyond 0.001630, hinting at potential profit-taking.

Fibonacci and Retracements

Fibonacci retracements from the 0.001516–0.001677 swing identified key levels at 0.001605 (38.2%) and 0.001646 (61.8%). Price found resistance near 0.001646 but retreated slightly, suggesting that this level may now act as a pivot for near-term action.

IOSTUSDT may attempt a test of the 0.001650–0.001670 range in the next 24 hours, but traders should remain cautious of potential profit-taking or pullbacks if volume fails to confirm further strength. A breakdown below 0.001600 would increase bearish pressure and risk of a retest of the 0.001570 support level.
