That RSI uptrend line holding while price rejects 86K is the most important signal on this chart.
Most people only look at price action, but the momentum divergence you spotted, with Fisher reversing before MACD, confirms this is profit-taking, not trend exhaustion. The 82.5K triple test is textbook resistance flipping to support if it holds.
Your point about higher highs remaining intact during a correction is key. Bearish reversals need lower lows to invalidate structure, and we haven't seen that yet. Even if MACD crosses down, a retest of 82.5K that bounces would actually strengthen the bullish case more than another green candle from here.
The older channel risk is real if 82.5K fails, but until that level breaks on a daily close, this is just noise within an uptrend. Patience over prediction right now.
