For equities traders at least, looking at the screen is often necessary during volatility as there's often unforeseen problems. Same reason firms use automation for every process but still monitor everything. I've done days where I don't look at anything but there's also a lot of instances where something somewhere fails and I need to attend.
I also follow the same strategy. If I feel like chances of loss are high, I just stop there because I always look forward to saving my money rather than making more money.
Except when you do that the market sometimes turns around and blasts off the way you originally planned for and becomes a massive winner. Instead of having a big winning profit (had you stuck to the original stop) you have a losing trade in your account instead.
I believe sticking to the plan is best. I would recommend you to control your emotions, trust your plan and go with it. If you lose, find the mistakes and learn from them.
No, I would try my best to mitigate the loss which is imminent. I would try to sell the stock at less profit or something but I will never let my hard earned money ruin.
%% GOOD; especially since a battle tested plan tends to be much better than instant or shallow trade moves...................................................................................Wisdom is profitable to direct.
When something unexpected happens I'd take the loss. You set a stop loss to keep your losses small. A smaller loss than planned is not going to hurt you.
