Simple button to Order Opening / Closing position

 
Hello, sorry, I'm new and do not know if this is the right section where you enter the topic.
I'm not a programmer and are not native English speakers, so I have some difficulty in finding information simple for me.
I'm trying to figure out how to create a button that allows me to open and close a position, being able to select a product with the chosen amount and whether to BUY / SELL.
You will say it already exists ... it's true, but I would like to make the selections first and then click on a button PROCEED.
Do you know if there is already, or what I should read or if there is down a button to easily deploy?

Thanks for your help

 

 

 

for any grammatical error is the fault of Google Translate ...))

 
 
Sorry, I forgot to add that I need to MQL5
 

you mean a button on the chart to trade 

and what selections do you mean?
