If you want to be a successful investor, you must focus entirely on observing the changes in the market when trading. The more volatile the market, the more we must remain calm and patiently wait. Livermore once said: "A successful investor must be like a successful businessman, able to correctly foresee future demands, purchase at the right time, and patiently wait for the moment of profit." Here, "at the right time" actually means waiting for opportunities to arise. Trading is a highly technical industry and a very rigorous job.
If you want to engage in this work for a lifetime, then patiently waiting is a fundamental lesson; being restless or having distracting thoughts can easily lead to setbacks in the market. The market does not always provide you with entry opportunities every day, so you do not need to be ready to trade at all times. We must patiently wait for the entry opportunities to appear in our trading system and then strike; learning to wait is a manifestation of execution ability.
