MT4 EA to 1.download data to csv / 2.run a python script / 3.open order based on python result

Hello,

I want to have a robot that can :

1. Download the past 200 periods Open/High/Low/Close/Volume data to a csv, on a specified period frequency (e.g .H1 / H4 / D1 )

• For example, if I specified the period frequency as H1. The robot will download the past 200 periods H1 data to the csv immeidately after the latest H1 is closed
• Need to add header to the columns on csv (Date/Time/Open/High/Low/Close/Volume)

2. Run the python script

• Basically, it is a script that will generate technical indicators and then will put into a model to predict the result.

4. Based on the result of the python script, open a buy/sell order in MT4

• If there is no existing trade in MT4, and the python signaled a buy > open a buy (market order)
• If there is no existing trade in MT4, and the python signaled a sell > open a sell (market order)

• If the existing trade in MT4 is a buy, and the python signaled a sell > close the existing buy and open a sell (market order)
• If the existing trade in MT4 is a buy, and the python signaled a buy > just keep the existing one and dont have to open a new one.

• If the existing trade in MT4 is a sell, and the python signaled a buy > close the existing sell and open a buy (market order)
• If the existing trade in MT4 is a sell, and the python signaled a sell > just keep the existing one and dont have to open a new one.

• The lot size of the order will be based on the ratio parameter
• For example, if the ratio is 30, and the account balance is 1000, it will open the lot size equal to the margin of 1000*30%

Parameters in the robot:

• Period: This can be based on the chart I put on the robot
• FX Pair: This can be based on the chart I put on the robot
• Magic number
• Name of the saved csv: (eg. c:/test.csv)
• Name of the python script: (e.g. C:/test.py)
• Ratio: (to calculate the lot size)

Things we may have to discuss:

• How to deal with end of day?
• Ideal output of the python?

Thanks
