if your statement is true and absolute then all we have to do is guess the direction the whale is moving, when we are behind them all will win even if you don't have any skills. Is that true?
Two very wise comments here. Of course the Whales do not need any indications and signals. They rather make the indications and signals as they have huge capitals to influence the market.
So they have no fear to loose because it is the common man who needs to fear and yes if you are able to get an insight into the direction in which the Whales would move, you would be on the safe side unlike those who act after the transactions are done and in that case suffer the consequences.
