Text file help

Writing data to a text file in mql4 is easy enough. Reading it back is a pain.

What I'm going to do is write a set of data at the top of every hour (for this example, we'll say Open, High, Low, Close, DateTime, SomeINT). Now, at the top of every hour, I don't want to add the data; I want to read what's in the file first, delete the data in the file, then write the new set of data. Data in the file will be from Bar[2] that will be deleted and the data written to the candle will be Bar[1].

Anyone got any ideas or links to good tutorials on how to do this? Google is letting me down today.

Thanks.

Not sure why you are having problems, it's pretty simple to do . . . just write the data to a CSV file and read back from the same. To write the data use FileOpen() with FILE_CSV|FILE_WRITE and this will open a new file even if one of the same name already exists, then use FileWrite() to write you values to the file . . . when you are done make sure you close the file with FileClose()

To read from the file open it using FILE_CSV|FILE_READ then use FileReadDouble() four times for the OHLC values, then use FileReadInteger() to get the datetime, and again to get the final int , again don't forget to close the file when you are done.
