Well, maybe its not real, just an urban myth.
But what if it is real? Do you want to be right or do you want to make a profit?
If your broker rigs their quotes so that you are drawn into a buy and they then push price downwards, this has to suggest a useful shorting opportunity (and vice versa). I’m not saying they rig the quotes as soon as you personally enter, but if you define strictly and covertly where you WOULD have entered, surely you would not be the sole lone trader on their books to go long at that point, some other traders must be doing likewise. So let them take the long side, then take their money. Identify the swing point and go short.
