I disagree with just about all of this. There is money to be made in the pre and post markets. I trade during those times and your percentage of losses is exaggerated, unless a person does not know what they are doing or choosing random stocks. Some stocks tank after the open and some do not. That is why you must look at the stock's pattern from the past to determine what it is likely to do now. There are certain times of the day when people buy and sell, and those times are generally predictable. News is not predictable but events like dividends and splits are. Many low-volume stocks perform consistently well. As to taking days off, you should be able to do that when you want, but every trading day is a brand new day, why dwell on what happened yesterday by sulking about it a whole other day, when you could be doing something productive, like making more money. Everyone doesn't tend to revenge trade, that is only a thing if you don't limit your losses, cannot control your "feelings" or whatever is going on with you. You seem to be putting limits on your trading for no reason, but you should do whatever works for you. Finally, I believe that men and women are completely different when it comes to trading. From what I can tell, you guys are way too emotional, especially with anger, which should not be a part of trading at all.
Never touch a third rail, never jump out of a plane without a parachute, never tug on Superman's cape ... but most of all I never listen to anyone who tells someone else to never do this in trading. Trading doesn't do never, always, will, has to, gotta, or wimpy hope it does.
