Generating historical range bar charts

I have a range bar EA that i use to produce the range bar charts i trade off.

It runs on the M1 and naturally can build charts only on the M1 data that is downloaded.

I would really love to be able to go back historically, say 3-5 years at least and produce range bar charts so that i can backtest and review- if anyone has any ideas how i can achieve this - to be honest it doesnt even have to be in mt4 itself, i would much appreciate it.

cheers

It depends on the size of your range bars.

For bigger range bars (say 20+ pip bars), using M1 data is probably going to be accurate enough. In this case, find as much M1 data as you can and convert it to range bars.

For smaller range bars (I use 7-pip bars), I truly believe you should always use tick data for both live and historical bars. In this case, download as much tick data as you can find (Dukascopy is a good source) and convert the tick data into range bars. You can use just about any programming language to convert the data into MT4 history files.
