Looking for help to code an Expert Advisor for MT5

Trading all pairs. 4H and 1 day time frame. 

It has three input parameters:

•  Period - MA calculation period;
•  First Range period - the first range (10 days by default);
• Second Range period - the second range (40 days by default).

Calculation of a Buy signal:

1.)Last Close > MAClose10 (10-day moving average of Close prices);

2.)Current MAClose10 > MAClose10 (10 days ago)

3.)Last Close > Close 40 days ago.

A buy signal is formed when all the three conditions are met. Opposite conditions apply for selling.

Stop Loss: 2X ATR (in pips)

Trailing stop:  4/3ATR when new lower low achieved.

Also close position if two conitions change.

 I need the source code of the EA and personal indicator that you will used

Kind Regards,

JA
