For me, all these points may all boil down to a single thought, that is if you are actually trading following the trading plan. With that, having risk management is already included knowing you can't do a successful trading if you don't have an effective risk management. Trade according to your set risks, and never do trading if it's beyond your trading risk management, that is if you don't want to end your trade at a loss.
Yeah, no matter what number they are, all of them are still important and should be considered if we are serious on this venture, so even if there are no numbers, it is completely fine. As we can see, risk management is not mentioned there but the guy above is right that the number 5 in the list sounds like it, though even if it isn't there, this is already understood no matter what we are doing (be it trading, investing, staking, mining, lending, gambling, doing a business, and so on..). Actually, without a risk management, doing a successful trade is still possible.
What I mean is we can push the transaction through but the thing is that the amounts that we are dealing with might be a bit high, or the assets that we are using are only a shitcoin, meme coin, or something. Like it or not, there will always be traders who are like this. They are hard-headed or too naive. Meanwhile even if we are following the proper protocol in trading, we can expect that losses are still there. It's normal and part of the game. The thing is, we can only worry less and can proceed to our next agenda, so trading like this is still better than trading the other way around.
