There is no secret. This is one man's rule. Others may prefer some other criteria for stopping out. Maybe a statistical measure or volatility measure or something else. Those looking at price alone must make decisions based on price behaviour.
Please define what "and move on" means. One person may define it as quitting for the day (assuming an intra-day trader). Another may think of taking a break based on some time parameter. Yet another may choose to wait for price to leave the trading range being formed before re-engaging the market. The devil's in the details - and so are the profits.
True. Trolls will of course latch onto the "rule" rather than note that I said "mine". One can use MAXOs. Or a stochastic. Or the RSI. Or any other of the umpteen oscillators. Or one can use a time stop. Or place a bracket order and go for a bike ride. What matters is having a rule whose results are what one finds acceptable. The specifics are irrelevant to anyone other than the trader who developed the rule.
Of course, anyone who actually trades and trades profitably knows this.
