How to determine the main force's accumulation through candlestick charts???

Simply put, before accumulating, the main force will test the market, including a small amount of accumulation, and then quickly suppress the coin price, or use market language to probe for any 'old stockholders'.

If there are no old stockholders, the main force will generally place low buy orders to accumulate, that is, placing a large buy order at the first buy price, and then placing a massive sell order at the third sell price, allowing small retail investors to transact at the first buy price.

After a period of collecting chips, with not much selling pressure left, the main force will occasionally raise the coin price to absorb some chips or suppress the stock price with little volume, washing out the market through fluctuations, and making intraday trades, that is, collecting chips while lowering costs.

In the picture below, the three waves are clear indications of accumulation and market washing.
