MACD crossover emulates you an indication of fast and slow EMAs crossover which are essentially mid-long term indicator of uptrend or downtred (fast EMA crossing slow EMA up is uptrend and the opposite is downtrend). RSI provides you a shorter term indication of overbought or oversold prices.

Theorically you can mix both indicators to deal with spikes.

Whenever MACD is crossed over for uptrend and RSI is oversold in a down spike it would be a good entry point if you are currently sold.
If MACD is crossed over for downtred and RSI is oversold, it would skip the buy order, protecting you of a bull trap spike.

Whenver MACD is crossed over for downtrend and RSI is overbought in a up spike it would be a nice exit point if you are bought
MACD crossed over for uptrend and RSI overbought in this up spike would protect you from selling in a bear trap spike.

Is is a double condition setup that works nice.
The hard part is achieving the optimal values for the indicators setups after several benchmarkings...
