anybody tell me if it is possible to input own data manually twice a day into
MT4 and display them as a line either in the main window, or beneath it? I
would like to do it for several currency pairs. The data has nothing in common
with the exchange rate of any currency. Will be input at 07.00 and 12.30 GMT.
should I store such data? What kind of code could read these data and display
it as a line?
Would it be a text line or a graphical line?
First you should write your own data into a (csv) file (in FILES directory) and then you can use a script, indicator or EA to read the data and plot on the chart. It is not much difficult but if you aren't able to code you should find somebody who can do it for you.
