this is a simple indicator that work on 5 and 15 minute timeframe.
Signal is based on this condition:
RSI below 50 in 5 minute tiemframe
RSI below 50 in 15 minute timeframe
MACD line below 0 in 15 minute timeframe
Price is below SMA 21 on the 5 minute timeframe
For more accurate entrys I like to combine the indicator with the VWMA 20 period.
