A whale accumulating is doing everything but big buys. He doesn't want to get caught so he's doing very small orders every few minutes for several days. I noticed hundreds of 0,013BTC orders the last few days.
You are right, whales use big buy orders to push and pump the price, but not in accumulation
I hear you. Saw sells in amounts of 2000-7000 yesterday that moved the price 200-300 satoshi, and then buys in amounts of 200-300 pushing the price up 500-600 satoshi to make the candle appear green at the end even though the majority of the volume were sells.
Quite sophisticated I think, must take much patience and monitoring.
