Structure & Formations

The price displayed a distinct bearish breakdown pattern from a 0.0366-0.0369 resistance zone before bouncing off 0.03522 (lower Bollinger Band), forming a bullish reversal structure. A bullish engulfing pattern emerged between 21:15-21:30 ET as price closed 0.034513 after a 0.03416 low. The 0.036281-0.036496 price range acted as strong support-turned-resistance, confirmed by multiple bounces in late October 22 trading.

Moving Averages

On the 15-minute chart, the 20-period SMA crossed above the 50-period SMA around 0.03585, forming a short-term bullish crossover. The daily 50-period SMA currently sits at 0.0367, with the 200-period SMA at 0.0364, suggesting a retesting of the long-term trend line. The 100-period SMA at 0.0366 reinforces that the recent move above this level is a critical inflection point.

MACD & RSI

The 15-minute MACD turned bullish after the 0.03522 support hold, with the histogram expanding and crossing into positive territory. RSI surged from 30 (oversold) to 55, indicating moderate strength in the rebound. While not overbought yet, RSI momentum is accelerating, suggesting further upside is possible unless capped by a key resistance level such as the 0.0366-0.0369 zone.

Bollinger Bands and Volatility

Volatility expanded dramatically during the overnight session, with SPKUSDT reaching the upper Bollinger Band (0.0369-0.0370) and then breaking above it with high-volume confirmation. The 15-minute BB width increased from 0.0003 to 0.0004, reflecting a sharp increase in order flow and positioning. The current close at 0.039035 is well above the 20-period BB midline, indicating a high-volatility breakout that could either consolidate or continue upward.

Volume and Turnover

Volume increased significantly during the late October 22 to early October 23 reversal, with a 3x surge at the 0.03522-0.0358 breakout. The largest single 15-minute volume spike occurred at 10:15 ET (October 23), with 19,833,121 units traded. This coincided with a 5% jump in price to 0.037412. Turnover and volume aligned well during the breakout, suggesting strong institutional or retail follow-through rather than wash trading.

Fibonacci Retracements

Recent Fibonacci levels on the 15-minute chart suggest 0.036281 (38.2%), 0.036496 (50%), and 0.036626 (61.8%) as critical retracement levels from the 0.03416-0.03984 move. On the daily chart, the 0.0367 (50%) level has held multiple times, with the 0.0364 (38.2%) acting as strong support. The current close at 0.039035 exceeds the 61.8% retracement level, indicating a potential continuation pattern.

Backtest Hypothesis

Given the strong 15-minute MACD crossover, bullish engulfing pattern, and 50-period SMA retest, a backtesting strategy using golden-crosses of the 20/50-period SMA on the 15-minute chart could be effective. A 5-day holding period, triggered at the 0.0358-0.0360 retest, may capture the overnight rebound. Integrating RSI divergence and BB expansion as filters could enhance the signal-to-noise ratio. With the current SPKUSDT structure showing momentum continuation, this hypothesis appears well-aligned with the recent price action.
