I want to share some trading tips for the beginner, use the moving average in the trade and use the candlestick. First set moving average 12 and 21 and follow Candle pattern. Moving average 21 crosses to verify the market trend. When the candle closes by crossing moving average 12. Find out if the candle closes below under moving average 21 and find out the sell. Hopefully, a profitable trade is possible if you trade in a completely formal manner.
Maybe you can add MACD too with 12,26,9 and RSI 14 and 21 so you can know more about the movement of the coin. It can also a guide to determine where the price trends although this is not always guaranteed always to work. But this is the basic trading that I use in every coin, and so far, this help me to decide to buy or to sell the coin, and it's very useful for me. Oh, don't forget to add moving average too because sometimes this line can give another guide for you.
