The best day trading strategy is the opening gap strategy. As the name suggests, day trading is a strategy in which traders open and close positions on a particular trading instrument during the day, but typically do not hold any positions overnight.
^ That is not easy like that, you need to have dig research first and choosing a coin is a start that you should must do first.
Day trading is a very risky especially in newbie and I wont suggest this to the OP, much better if OP will find another way of making profit because this is not a kind of making profit easily. Probably, long term trading is a good advice to those newbie who wanted to start in trading because they can manage the risk if they hold it a long term and trading long term.
