Simple rules for using the MACD indicator:

When both the price and the MACD are rising, the market will continue to strengthen, so do not short! Wait until the price is still rising, but the MACD starts to decline, then it indicates a weakening trend.

When both the price and the MACD are falling, the market will continue to weaken, so do not go long! Wait until the price is still falling, but the MACD starts to rise, then it indicates a strengthening trend.

If the daily chart shows a double top divergence (price makes a new high, but MACD does not), be sure to short with low leverage.

If the daily chart shows a double bottom divergence (price makes a new low, but MACD does not), be sure to go long with low leverage.
