Simple EA with 3 indicators Mql4

Good morning to all, 

The objective of this project is to create an Ea that works with 3 indicators: Line Regression, EMA (Exponential Moving Average) and VWMA (Volume Weighted Moving Average), that will trade in specific times and will not trade in 5 specific dates.

The Ea must have the option to setup a the indicators lengths,  specific magic number,  add comments, set lot size, change trading time and change no trading dates as you can see in image 1.

The script must be in a format that can be modify

The indicator must have the option to be backtested

The indicators must be plotted / included in the chart

There’s has to be dotted lines between the point of entry to the point of exit image 3

The way to validate the Ea is to implement it in as much currencies as the freelancer decides and review it at the first trade no matter the currency.

Trading Logic:

VWAP length 50

Linearregresion length 50

EMA length 50

1. Open long when the Regression Line is above of the VWAP line and when Regression Line is above of Ema
2. Close Long when any of the previous conditions changes
3. Open Short when the Regression Line is below of the VWAP line and when Regression Line is below of Ema 
4. Close Long when any of the previous conditions changes
