Hello , consult this expert advisor code . Why an expert advisor ? indicators cannot trade , the script can be used and setup with a hotkey by default like this :
So if you want to create a buy script and set it up to fire with this method its very easy .
Now , in case you want to go the route of the expert advisor , which will also allow you to have inputs per the lot and stop levels etc later on you can consult this code :
