Using Reuters/Bloomberg/OANDA historical data in charts/indicators

 

Hi all,

I would like to use in MT5 the external historical market data, manually fetched by me from Reuters/Bloomberg/OANDA - say, 1m implied Risk Reversals.

The data is stored in CSV files (timestamp and one or more value columns). The records are rather of low frequency (daily or hourly).

What is the easiest and/or the most convenient way to make this data available in MT5? 

As a first step, I want them to be charted aside of symbol chart, similar to Volume subchart.

Any hint from you will be strongly appreciated.
