The OP himself said here that he is new so he needs to learn about cryptocurrencies first. There is no hard-and-fast rule to use a specific indicator on a trading platform. You can trade by your personal strategy. But remember that if you make a mistake on the trading platform, then you must bear the cost of the mistake. Also remember not to be too greedy in trading platform at all times. Those who lose more on trading platforms lose for only one reason and that is greed. Always avoid this greed. Secondly, never trade with emotion, always keep yourself in control and trade. If you follow these rules, hopefully you will not lose on the trading platform.
