The market is a superlative enemy much larger and stronger than you, and your only hope in getting out alive, or perhaps with a little more than you put in, is to get out when things are not going well!
There is no point in entering a game you are sure to lose, so don't do it unless you know what you're doing. If you have to ask, you don't know what you are doing.
I don't mean to demoralize you, it will happen soon on its own unless you study the only realities available to you, the small trader on a retail console.
1. Money is created or destroyed based on faith, or its opposite which is fear. Note that fear of missing out always results in loss, unless you have faith in your exits.
2. Money is good, and so is business. No one would cooperate for very long without it. Therefore go into business serving the market's needs. Right now it needs price discovery in a major way. Everyone is beginning to look down.
3. Trading is nothing more than accumulating inventory on the cheap so you can provide it later when people didn't realize they needed it. Sounds basic, but chasing price is the opposite of stepping in at the bottom to give the wounded a way out.
4. Therefore enter the market knowing what you are doing, and knowing who is going to need to buy your positions later. If you can not do this, it is only a matter of time before your "edge" is found out and obliterated......
