The whale indicator seems to play like an even more predictive Breakout indicator, if you can spot a wedge/triangle/pennant's formation.
So far it's been perfectly accurate on COINBASE:BTCUSD on 15min candles, and I haven't tried this with alts yet.
This also may not apply to large formations that are only REALLY visible on large timeframes, since long-term whales tend to mask their presence well on low timeframes.
