An Expert advisor based on moving averages and candlestick pattern needed

The idea of the trading system is as follows: 

• Market entries are performed when the 2 moving averages intersect, the candlestick touches or breaks through  the opposite moving average line of the moving average that just crossed but the overall trend has remained the same. 

• The trend is determined by the MACD based on the settings 34 for fast EMA 144 for slow EMA and 9 for MACD SMA. When the MACD is an above the zero and the signal (red) line is below the yellow histogram ticks the trend should continue moving up. Alternatively, when the MACD is below zero and the signal (red) line is above the yellow histogram ticks the trend is considered to  continue moving down.  

1. Buy signal: the Moving Average (50) has crossed the moving average (200) & the candlestick has either touched or moved below the moving average 200 line. Only if the above criteria is met, the next part of the signal is once the MACD (34, 144, 9) signal (red) line is below the (yellow) histogram or if it has been below the (yellow) histogram for at least one of the previous 5 histogram ticks before the candle that broke the MA while the histogram remains over zero which shows continuance of the up trend. In addition to the criteria above, the final part to solidify the signal is that the MACD histogram (yellow) ticks need to be at 0.032720 or higher for a buy alert to be sent

1. Sell signal: the Moving Average (200) has crossed the moving average (50) & the candlestick has either touched or moved Above the moving average 200 line. Only if the above criteria is met, the next part of the the signal is once the MACD (34, 144, 9) signal (red) line is above the (yellow) histogram or if it has been above the (yellow) histogram for at least one of the previous 5 histogram ticks before the candle that broke the MA while the histogram remains under zero which shows the continuance of a down trend. in addition to the above criteria, the final part to solidify the signal is that the MACD histogram (yellow) ticks needs to be at -0.009925 or less in for a sell alert to be sent  

These are the forex pairs id like to have monitored using 15 minute timeframe: 

1. EUR/USD 
2. USD/JPY 
3. AUD/USD
4. GPB/USD 
5. EUR/JPY 
6. GPY/JPY 
7. USD/CAD 
8. AUD/JPY
9. USD/CHF
10. EUR/GBP
11. USD/MXN 

Risk: 

• Once a  buy alert is sent for a specific currency, if a change of direction occurs after and the MACD falls below the zero (indicating a downtrend) for that currency after I would like a notification sent 
• Same thing for a sell alert, if a change of direction occurs after an alert was sent and the MACD rises above the zero (indicating an uptrend) for that currency I would like a notification sent 

Criteria: 

1. MA 50 has crossed the MA 200 or the MA 200 has crossed the MA 50
2. If the MA 50 has crossed the MA 200 we want to wait until the candlestick comes below red line (MA 200) and if the 200 MA has crossed the 50 MA then we want to until the candlestick goes above the green line (50 MA) 
3. Reference pics below—-if the above criteria is met and with our MACD settings (34, 144, 9) they show that the trend is still on a CLEAR uptrend or downtrend and that’s when I want an alert sent. If 200 MA (red line) breaks the 50 MA (green line) we need to make sure that the MACD reflects this with the signal (red) line being BELOW the yellow histogram while the histogram is under  zero at the same time that the candle is breaking the 50 MA. The Histogram (yellow)  tick needs to be at -0.009925 or lower at the same time the signal line is below the histogram. 
4. If the 50 MA (green line) breaks the 200 (red line) MA and the candlestick falls below the red line (200 MA) we need to make sure that the MACD reflects this with the signal (red) line being ABOVE  the yellow histogram while the histogram is over the zero at the same time that the candle is breaking the 200 MA. The histogram (yellow) tick needs to be at 0.032720 or higher at the same time the signal line is above the histogram.
