need help, please! How to access/read MT4-hst-Files into MT5-arrays?

Hello,

I want to access USD/RMB and USD/MXN history data (.hst-files) from my MT4, and work with these data in an array of a MT5 indicator buffer. How can I accompolish that, please?

You can create your own indicator which is based on data from a file. See as example ColorCandlesDaily

Rosh, this is not it. ColorCandlesDaily doesn't access data form a file. It refers to the current symbol and redraws it in an indicator window, using a distinct candle color for each day.

I want to get history data into an indicator buffer. My current try, not finished yet: I am using the well known period_converter_opt.mp4 on a 1-min USDRMB chart and on a 1-min USDMXN chart, both GCI-Demo-MT4. These export the quotes to csv-files.

Hence MT5 cannot access that file, since MT4 can only write in its own files directory and MT5 can only read from its own files directory. So I wrote an AutoHotKey script that copies the MT4 csv files to the MT5 files directory, every time the filesize changes.

Now in MT5 I am currently into programming the OnInit section. It is supposed to open and read both csv file to a buffer array. Later I will extend my OnCalculate routine, so that it updates the array, every time the csv disk file changed, because it was copied again.

Oh, I am a newbee and things are hard work. I hope some professional reads this and just drops the two or three lines of code I need to accompolish what I want :-)

You need:

• read history file
• parse it
• fill indicator buffers

That's all

• read history file
• parse it
• fill indicator buffers

yes, but where to find the history files's data sturcture ?

data sturcture  of  those .hcc  file in Mql5 are not known ?
