Catastrophic movement because of an unknown variable that can happen anytime and cannot be known before it happens. An institutional size trader's wife wants and demands a new multimillion dollar home by that evening or she is history so he vacates his large position size to buy the house and save his marriage and bam the instrument plunges..traders screaming..wife smiling...husband frowning...real estate broker eating ribeye. Or internet goes down. Broker passes out...computer burns up. And his trades not server side. Or Flash crash..institutional algo gets stuck and moves price fast against his position.
Totally understood. I faced same problem. On top of that some traders complain hindsight. So, I started recording my screen as the trades took place live. Some still scream hindsight! Just do whatever you can do without compromising your trading skills. No matter what you do some folks will disparage what you are doing. Your job is to produce a winning trade not please the public. Keep your focus. It is your journal. Viewers of your journal either believe you or they don't. For some you will find it is a never ending battle no matter what you do help them believe you. So just do what you can and let the tree falls where it falls. Others are more generous in watching what you are doing. One other thing use YOUR system. Trade "how" it has been working for you the last 24 months. Trade how you know to trade not what others tell you.
