Indeed, there are many TPS tips that have been shared on this forum, and quite a few have failed to be implemented. It must be admitted that it is very difficult to regulate emotions and psychology in investing, especially when it comes to fear and greed. But this is the most important thing in psychological science trading. No matter how great your technical knowledge is, your psychology is not strong. I'm sure it won't work, many profits will be missed because of greed, because it's hard to fight the urge to want more profits. So I think this first point is really very important in maintaining psychology.
Taking profit is what we want to do most for investing or trading but if we forget the Principle #1, secure our capital first, our capital first, we will not have chance to take profit.
Because if we don't have "(Initial capital first" in minds, we naturally will have less careful or even careless investment, trading decisions that will open very bad and risky investment or trading positions. At the end, with such risky positions and with bad control of emotion, psychology, we will either exit with loss by ourselves or will be liquidated by exchanges with their liquidation bots.
