According to my experience in trading in cryptocurrency more to use the Moving Average (MA), because MA is an indicator of the trend-line moving lagging, or slower than price movements. The moving MA line indicates an uptrend or bullishness, while the downward MA line indicates a downtrend or bearish trend. I also use two MA lines with different periods to determine the open position signal. For example, MA 20 and MA 50. MA 20 which is MA 50 from top to bottom produces bearish signals, so I can open short positions. On the other hand, if the 20 MA 50 is from the bottom up, this indicates a bullish signal to open a long position.
