It’s a multi timeframe period converter for MT4 based on the MT4’s default period converter by metaquotes. It can show you real-time m2, m25, h3 or any timeframe you want MT4 to show.
How to use:
Copy the mq4 file to your MT4 indicators folder (experts\indicators) to install it as an indicator, NOT script. then in the custom indicator list, attach period_converter_opt to the chart you want.
PeriodMultiplier: new period multiplier factor, default is 2
UpdateInterval: update interval in milliseconds, zero means update real-time. default is zero.
Enabled: You can disable it without remove it with this option.
Other parameters are comments or for debugging, it is safe to ignore them.
Also Make sure you have Allow Dll imports option checked in common tab or it won’t work
After that, File->Open Offline to open the generated offline data. then the offline data will be updated automatically.
As long as you keep the source chart open and the converter indicator running, the generated chart including indicators inside will always be updated. also you can close the generated chart and open again later from File->Open Offline without problem.
If you want to quit MT4, you can leave those offline chart as other normal online charts. when you start MT4 next time, those charts will also be loaded and updated.
