MACD + EMA System with Alerts

So I created the MACD Cross Strategy but not working alone by itself. I added EMA (Exponential Moving Average) filter to improve its winning rate so the MACD Signal only appears when in the same trend direction as Moving Average.

The Main Rules for Long Signal are:
- MACD Main Line Crossover the MACD Signal Line.
- The crossover happens below the MACD center line (0) so the momentum is strong.
- Price above the EMA 200 so it means the market is in a strong uptrend.

The Main Rules for Short Signal are :
- MACD Main Line Crossunder the MACD Signal Line.
- The crossover happens above the MACD center line (0) so the momentum is strong.
- Price below the EMA 200 so it means the market is in a strong downtrend.

The signal crossover & signal alert only generate as per the following rules above.
