Actually there is a way used on the penny stocks market. The 45 days moving average. When it starts going up, people start buying into the stock, it means it won't go any lower, all weak hands folded for over a month, possible minimal price. Example: https://bittrex.com/Market/Index?MarketName=BTC-GRID (super shitty 100% PD coin making sudden comeback).

At this point however, big whales will control the price by wiping buy support then replacing it with their own. And the whales start to fight over each other for the lump of stocks.

And then, they find idiots to put up buy support 200% higher. And they convince them the price is the best, they start selling into them for days/weeks.

You think whales make their bang during the run-up? No, that's just bagholders bagholding each other, no whale could profit at those prices, they instead cash out long before the peak. 200% on 10 BTC is better than 2000% on 1 BTC.
