You know you are wrong when it hits the part of your trading plan where you quantify what is an out for your plan, and/or it is time to stop trading as the markets aren't performing within the metrics prescribed in your trading plan. For the kind of volatility you use as an example, you are either set up in your trading plan to take a trade and except your stop may be blown through before a fill, or after the first loss you identify this isn't a market you should be in at the time. Another part of trading is having a plan to sit on the sidelines and not have to trade every up and down.
Take this as you will, but just based on the giant, colored, capitalized response to a simple comment on a trading forum, this may not be the business for you. Intense up and down emotional people more likely aren't suited for trading, as they react too strongly to a win or a loss, and go big, or revenge trade when they need to stay cool, think, and rely on their plan.
I hope you have a written plan, have studied it, practiced with it, and stick to it.
Peace
