In trading, everyone expects to buy low and sells high. I believe that it is common thinking for all and we all want to gain some profit from trading. Strategy will not same except it. Other things can be different but expecting Profit from buying will be same as I believe.
It is like this, I never follow anyone's instructions, before I used to follow the signals of many groups on telegram, but the success rate has not been the best in these cases, I lost a lot of money following them, the strategy of buying low and selling high is what is always sought, the case of investment is something else.
